Update 07:54 UTC :  immigrant workers, weather, solidarity
- Tension in a shelter in Finale Emilia. A group of North African laborers and their families were not amused at all when they were initially not granted admission in the shelters setup by the Civil Protection.  Civil Protection said that it is always giving priority to the children and the elderly.  After some fierce discussions, everybody was happy again, as there was enough space for everybody.
- Part of the tension in the above shelter is caused by the rainy weather. Staying outside in the rain is horrible for everyone.  One of the first elements Earthquake-Report.com looks at when an earthquake strikes is the weather at the time of the mainshock and the weather outlook. This morning temperature at Finale Emilia was only 10 °C and it is raining non-stop since early this morning.
- Authorities are asking all Italian people to show their solidarity with the victims of the earthquake. A plea in that sense was made by the President of the Emilia Romagna, Mr. Errani.

Update 07:54 UTC :  building code, European Union, Insurance companies
- A lot of specialists are really surprised about the number of modern facilities (some were build in 2000) who collapsed during the earthquake, especially industrial equipment and buildings.  The chief of Civil Protection told the RAI earlier today that this kind of collapses should be studied very carefully and that lessons should be learned.

Lack of a European building code !
Although construction engineers have expressed already many years that the lead in a better building code should be organized by Europe, individual countries have decided (by means of their Ministers), that building codes should be kept National. Such a legislation is highly needed and can have enough exemptions for poorer countries, but at least new buildings would enjoy a far better resistance to earthquakes than today. Earthquake-Report.com is one of the advocates of a European earthquake-resistant building code. 100% protection is not possible, but earthquakes up to M7 or even more should not trigger collapses.
Insurance companies can also take the lead in earthquake resistant building methods. Refusing to insure not adequately build constructions should conduct owners to improve their constructions.

Update 21/05 – 07:24 UTC :  aftershocks, PM Monti
- The area has been shaken by 18 aftershocks since midnight UTC. The strongest one being a M3.5, which will have been felt as a weak shaking by the people living in the epicenter area. Earthquake-Report.com sees aftershocks of M4.5 or higher as a real danger for unstable buildings. So after all, we can conclude that people must have had an acceptable night.
- Since the mainshock during the night of May 20 until now, 150 aftershocks were recorded. 90% of these aftershocks could not be felt by people, but were recorded by sensitive seismographs from INGV.
- Prime Minister Monti has decided to return to Italy earlier than planned because of the earthquake. After meeting world leaders during the G8, mr. Monti should have traveled to Chicago to take part in the NATO top summit.  He now decided to return to Italy.

Update 22:41 UTC :  Civil Protection, false Facebook calls
- The Italian Civil Protection has prepared 4500 beds for people unable to spend the night at home
- Malicious persons have send (so called official) messages via Facebook to call the people to leave their houses for the night. The Police and Authorities have informed the people that they NEVER called for such action.  Police is thinking that people try to loot houses this way.

Update 21:36 UTC :  scary for the night
A lot of people from the direct epicenter area have decided to spend the night in their car  as they are scared for severe aftershocks. Shelters are only used for people who cannot return to their houses

Update 18:34 UTC : Anna Firs, an elderly woman of 86 years got sick at the time of the earthquake and perished in a hospital because of a heart attack later today. Anna Firs lived in Vigarano Mainarda.  This brings the number if indirect fatalities to 3 and the total to 7.

Update 18:25 UTC : INGV has announced that they cannot rule out another severe aftershock.
In fact NOBODY IN THE WORLD WILL BE ABLE TO PREDICT THE TIME or STRENGTH OF WHATEVER EARTHQUAKE or AFTERSHOCK.  As we said earlier today, aftershocks are normally weaker than the mainshock but this is only theory.  A good example of this exception theory was this weeks M4.8  Aftershock at Timpson, Texas. The mainshock occurred 7 days earlier and had a Magnitude   of M3.9!.

Update 18:20 UTC :  Mantua, Modena, shelters, highways
-150 people have been listed by the Mantua authorities for shelter for the night. They are unable to return to their damaged houses
- Modena has installed temporary shelters for 2000 homeless people
- The regional highway authority was happy to tell the press that NO problems were reported in their regional network of more than 400 bridges, viaducts, tunnels, etc

Update 18:13 UTC :  Rovigo churches,  firefighter,  cultural heritage
- Churches have been closed for further inspection in the Rovigo province.
- A firefighter who fell from a roof when the building he was inspecting during an aftershock collapsed is conscious again. Good news, but a further proof that these people are taking great risks to get close to unstable buildings.
- The vast cultural heritage in between Modena and Ferrara and especially in Emilia Finale has been suffered enormously.

Update 17:54 UTC :  aftershocks, hospital, PM Monti
- We have just counted 64 aftershocks since the mainshock at 02.03 UTC
- Civil protection will be helping with the evacuation of the hospital in Finale Emilia
- Prime Minister Monti, currently in Chicago for the G8 meeting, has said that he will do everything in his power to cope with the situation.  He is constantly updated by the responsible presidents of the damaged provinces.
- The Sant’Agostina area has suffered seriously from the M5.1 aftershock from this afternoon.

Update 17:13 UTC :  anti-looting, missing persons
- Police have organized anti-looting patrols to take care of unattended houses and buildings
- The president of Emilia Romagno has said to the press that nobody is missing anymore, making it probable that the current list of killend and injured people will remain as it is

KEEP FOLLOWING OUR NEWS REPORTS – EARTHQUAKE-REPORT.COM is probably the only specialized earthquake reporting website in the world combining scientific information with human impact information.

Update 16:21 UTC :  displaced people, additional damage after aftershock, power, animals
- Because of some cracks in Mantua’s Palazzo Ducale, the fire department has decided to close the building for the public
- The number of displaced people (people who cannot return to their houses) is currently estimated to be 3,000.
- The M5.1 aftershock was responsible for the additional collapse of a still standing part of the Sant’Agostine town hall
- ENEL, the main Italian power company, said that besides some isolated cases, all users have electricity again.
- Misery for a number of animals too. A number of stables have been collapsed and at least a herd of cows and breeding pigs have been covered by the rubble. We expect more livestock to be in trouble as everybody knows that stables are often in a bad condition.

Update 16:00 UTC : prisoners evacuated, telecommunications and Railway line working again
- Italian Railways have reopened the Bologna – Verona railway route.
- The Modena province has asked the national government to take urgent measures to help the owners of damaged houses and businesses. An extension in time to enter tax forms isd one of them.
- The 200 users cutoff from Telecommunications at Finale Emilia have been reconnected
- 500 prisoners have been evacuated from the Ferrara prison. Some of the prisoners were maffia linked and had to be kept away from others because of testimony programs.

Update 15:27 UTC : Damage will be huge!
Earlier in this article, we have reported to believe that the damage would go into the hundreds of millions of Euro’s. We will have to boost this damage considerably as a lot of factories and buildings may be found unstable to continue producing goods.  This economic damage will be added on top of the structural damage to buildings. James Daniell, an earthquake damage specialist working at Cedim Germany, will certainly be able to produce a very good estimate by tomorrow afternoon.

Update 15:21 UTC : Strong aftershock
A M5.1 aftershock struck the epicenter area at 13:18 UTC (15:18 local time). The depth of the hypocenter was at 8.9 km following USGS. INGV, Italy seismological institute, reports the same Magnitude but a depth of 5.1 km.
These continuous aftershocks are bad news for the people in the greater earthquake area as they will go on for many hours and will last at least until tomorrow, meaning that a lot of people will have to spend the night outside their own houses.  The aftershocks will gradually weaken, but the situation will be at least unstable for a limited number of days. The epicenter of the last aftershock was very close to Ferrara, much closer than the mainshock.  Normally, a M5.1 earthquake is not really damaging, but in combination with already unstable buildings, such shocks will be capable to increase the amount of damage considerably.

List of the deceased (5 in the Ferrara province and 1 in Bologna province)
- Nicholas Cavicchi, 35, resident of San Martino (Ferrara) and killed while working in factory in Sant’Agostino
- Ansaloni Leonardo, 51, resident of Reno Centese (Ferrara) and killed in the same factory as Mr. Cavacchi
- Gerardo Cesaro, 59, resident of Moline.
- Tarik Naouch, 29, residing in Crevalcore. Mr. Naouch was killed in the Ursa factory in Ponte Rodoni di Bondeno
- Nerina Balboni, 103, got a heart attack when she was buried partly by debris
- 37 year old German woman died of a heart attack in Bologna (we are still searching for her identity)
Earthquake-Report.com pays his respects to the family of all the deceased.

Update 12:19 UTC :
-The President of the National Council of Engineers has said that all efforts have now to be invested in more earthquake-resistant buildings. He mentioned especially the need to further stabilize historic buildings, one of the main damaged building types during this earthquake.
- The President of the Lombardy province, Mr. Roberto Formigoni, has joined the plea of the President of Emilia Romagna to call the State of Emergency in the earthquake damaged areas. Mantua, another seriously hit area is part of Lombardy.
- Schools will be closed tomorrow as inspection of school buildings will take place

Update 11:31 UTC :
- The number of people killed directly or indirectly remains the same
- Fifty people have been reported as injured
- The body of Gerardo Cesaro, worker at the Tecopress company has been recovered from below the rubble
- Italian President Napolitano has send his sympathy to the family of the killed people and has also send words of thanks to the  SAR people and all people involved in helping the victims of the earthquake. President Napolitano is constantly updated from the situation by the Italian Civil protection.
- Aftershocks are continue to strike the area.  At 11:13 a M4.2 aftershock made it very clear that the dangerous hours are not over yet. Stronger aftershocks are very exceptional but occur from time to time.
- The President of Emilia-Romagna has asked the National Government to call the state of National Emergency for the area.

Update 09:55 UTC : Mr. Gabrielli, chief of the regional Civil Protection has declared that the situation is “under control”. Mr. Gabrielli told the press that he has overflown the greater earthquake area and that he has not seen serious problematic areas. Traffic is going smoothly, infrastructure is almost intact and damage is not widespread.

Update 09:47 UTC :
- Italian Civil Protection is organizing shelters for people who’s houses have been damaged by the earthquake.
- tens of people have been injured during the earthquake. The devastation is not widespread. Only isolated houses and buildings have suffered serious damage. We expect not earthquake-resistant building methods to be one of the major reasons that such serious damage has been inflicted.
- The collapse, partial collapse and damaged historic buildings are currently visited by Civil Protection and Local authorities to become a clear picture of the amount of damage.
- Earthquake-Report.com is increasing the expected amount of damage into the hundreds of millions Euros.  This amount not only includes damage to buildings and historic sites but also to the economy.

Update 09:23 UTC : INGV has reported 41 aftershocks so far, the strongest being a M4.9 at 03:02 UTC (05:02 local Italian time). 5 aftershocks measured M4 or higher and 14 aftershocks in between M3 and M4.

Update 09:15 UTC : The Mantua area was also seriously damaged. The church of Felonica in Mantua was damaged.

Update 09:11 UTC : Many people in the greater epicenter area remain in the streets fearing for aftershocks.

Important Update 08:56 UTC : The death toll has increased to 6 when a worker was found under the rubble of the Tecopress factory at St. Augustine (Ferrara). 4 are considered in earthquake terms as shaking deaths, 2 people have been killed indirectly (see below).

Update 08:47 UTC : Click on the pictures below to see more images of the damage inflicted by this deadly earthquake.

Update 08:35 UTC :  The Chief of Civil Protection from the Ferrara province has just arrived at the Prefecture office and is now leading an assessment and operations meeting with his staff.
- Based on the many images we have seen so far, the damage will run into at least tens of millions of Euro’s, probably a lot more. Some historic buildings have collapsed completely, others partially. Industrial warehouses have been damaged. So far we have NO immediate numbers of injured, but a lot of people living in damaged houses must have at least minor injures.

Update 08:26 UTC :  To give our readers an idea of the extend of the damage, we have combined a “before” and “after” image of the Castle of Finale Emilio. The angle is not the same, but you can see very good that the towers have almost completely collapsed.  Images courtesy and copyright of its owners, damaged castle from Gianluca Diegoli via twitter and the “before” picture from animoweb.it.

Update 08:18 UTC :  The earthquake was also felt in the neighboring countries. We got I Have Felt It reports from the Alps region, Slovenia and the Cote d’Azur (France).

Update 08:09 UTC :  2 helicopters of the Italian Police are overflying the earthquake hit areas and are trying to locate and to guide SAR forces (Search and Rescue forces) to eventual collapsed or heavily damaged buildings. These overflying helicopters are especially looking for old abandoned houses were often poor families are residing.

Update 08:01 UTC : The Palace of Venice, an historic building in Finale Emilia, badly hit by the earthquake, is partially collapsed. The 11 people from three families who lived there were rescued by SAT personnel.

Update 07:58 UTC : It is still not sure how many people have exactly perished during this earthquake. We have counted 4 so far, but the number may increase slightly. Let us make an overview.
- 2 indirect fatalities (a 37 year old ill woman died probably of an heart attack and a 100 year old person probably from the same)
- a Moroccan worker died in Ponte Rodoni, Bondeno. He worked at Ursa, a polystyrene foam company, and his shift would end at 5.  He was killed when a support beam collapsed on his head.
- 2 Italian workers were killed when a roof from a ceramics manufacturing company collapsed on them. Theur work shift would have ended at 6.
3 shaking deaths and 2 indirect killed people is the sad result so far.

Update 07:45 UTC : A 5 year old child was rescued out of the rubble in a collapsed building in Finale Emilia !

Historic earthquakes map courtesy INGV - earthquake in between M6 and M7

Update 07:32 UTC : The earthquake’s epicenter was located in a area which has no damaging earthquakes since a long time.  We have to go back to 1570 for a major earthquake near Ferrara and to even 1346 for another M6 to M7 earthquake at a distance of approx. 20 km from the current epicenter. From 2002 to 2008 6 smaller earthquakes (less than M4) occurred within a radius of 20 km.

Update 07:17 UTC : A lot of people are asking themselves why an earthquake with (only) a M5.9 Magnitude can inflict such a lot of serious damage.  Not only was this earthquake very shallow (close to the surface), but one of the main factors is that the earthquake occurred in a relatively soft soil area. Soft ground layers are propagating the earthquake waves a lot stronger than areas with harder rocky layers.

Update 06:41 UTC : 2 earthquake of respectively M4.1 and M2.2 were precursors of the damaging M6 mainshock. Since that mainshock, INGV has recorded 12 aftershocks!

Important Update 06:39 UTC : We are sad to tell that a 4th fatality has been reported. We have also a few more details on the killed people. All of the death people are coming from the Ferrara area. 2 people died in a pottery factory in Ferrara. A third person died in the Ferrara Bondeno industrial zone and the 4th victim was a 37 year ill woman who died of an heart attack.

Update : The video below shows the damage to a couple of buildings in the Ferrara area.  The shaking must have been very strong to inflict this kind of damage.

Update : The video below is mainly a picture from a damaged building combined with an interview with the Governor of the Ferrara province (in Italian). The governor talks about a lot of damage to bridges, schools, historic buildings etc. She calls the situation very serious.

Update 06:35 UTC : In San Felice sul Panaro, near Modena, the tower of the fortress collapsed. Another tower went down in Finale Emilia, and a nursing home was evacuated.

Update : Mostly historic buildings have been damaged in the quake. Click here for series of images from La Repubblica.  Some churches and older buildings collapsed completely.

Update : The 3 killed people are believed to be 3 farm workers in the Ferrara area

Update : The heavy shaking lated for about 20 seconds

Update : As what can be expected, everybody ran to the streets after feeling the shaking.

Update : A church bell collapsed in Ferrara, in Finale Emilia a church steeple was reported damage, in San Felice Parano a segment of a castle collapsed.

Update : USGS has upgraded the earthquake to 6.0 at a depth of only 5km. The updated PAGER says 73,000 people would felt a severe shaking!! and 178,000 a very strong shaking. Avery bad sign.

Update :  An also strong aftershock M5.1 occurred 59 minutes later

Important Update 17:40 UTC :
CHILE side of the border
The Tarapaca governor reported earlier today that :
- Some walls have collapsed in the Arica port area
- Power was cut in 15% of Arica’s households (3000 families)
- some roads are / where  inaccessible (ie route 5)
The governor also said that local people had the feeling that the quakes intensity was stronger than VI which was reported by Chile’s ONEMI.
- Although the authorities never called a tsunami alert as the hypocenter was below land, a lot of people have auto-evacuated to higher grounds
- Luckily there are NO reports of injuries
All these data are for the Chile side of the border
Peru side of the border
- As could be expected, also TACNA had power cuts
- Walls and roofs fall in the area, a water pipe broke in Para sector and cracked windows in stores.
- TACNAschools like “Francisco Antonio de Zela” and “Coronel Bolognesi” showed fissures in walls.
- Landslides in the road of Ilabaya and cracks on irrigation canals of Candarave
- 5 people did jump from their houses causing them to be injured

Update 11:33 UTC :  IGP, Peru has also other earthquake data. Ml5.9 at a depth of 105 km. Epicenter : see below (Peru side of the border). IGP Peru has calculated that based on their earthquake data Tacna would have experienced a MMI IV light shaking and Arequipa a MMI III weak shaking.

Shaking map courtesy USGS

Update 11:03 UTC : ONEMI Chile, the outstanding emergency authority in Chile, is calling the earthquake “mediana intensidad” (moderate intensity).  The strongest Magnitude has been given to Arica (MMI VI or strong shaking). At Earthquake-Report.com we use MMI VII as a beginning of chances for serious damage. MMI VI can generate small effects like falling objects, cracks in walls etc.

Update 10:58 UTC : Theoretical calculations (based on USGS data) have reported that 295,000 people will have experienced a MMI V moderate shaking. 1.9 million people a light shaking and 2.24 million people a weak to very weak shaking.

Update 10:53 UTC : Universidad de Chile (to be trusted highly) reports a Magnitude of Ml6.4 at a hupocenter depth of 119.6 km (good but still serious earthquake numbers). Universidad de Chile Santiago, is putting the epicenter close to Tacna, Peru. Both EMSC and USGS have located the epicenter in Chile!

Update 10:52 UTC : Tacna has reported a moderate shaking (MMI V). The earthquake was felt as far as Arequipa in Peru and Arica in Chile. Deep earthquakes are felt in a far wider area than shallow earthquakes.

Update 10:49 UTC : Preliminary earthquake numbers can be very tricky during earthquakes. There is a night and day difference in between the depths of 20 or 90 km. The first can be highly damaging.  These depths are rarely noticed in the area but they occur, so there is no certainly of what really happened at the beginning.

Update 10:47 UTC : We have removed the text “very dangerous”  from the title because the depth value of USGS has changed from 22 km to 98 km.  The Magnitude however has been increased from 5.9 to Mw6.2. In general we can say that a 90+ km depth would only be capable to generate minor damage or injuries. Only a few exceptions can be more damaging.

Update 10:41 UTC : the earthquake occurred at 06:00 AM during the early morning hours when a lot of people are still asleep.  This is always a bad period for earthquakes. On the positive side is that daylight will have started. We have NO reactions from the area as of yet. We call upon our readers from the area to at least give us a few more details on the time that the strong shaking lasted.

Update 10:37 UTC : We have changed the title and have added “very dangerous” to the already existing text. Why ? Because EMSC has increased the Magnitude from 6.0 to 6.4 – Depth at EMSC has been reduced in few time from 80 to 40 km. Bad numbers !

Update 10:35 UTC :  12 minutes later, a M 4.0 aftershock struck the same area.

Update 10:33 UTC :  Initial reports from USGS and EMSC are locating the epicenter in different countries (EMSC in Peru and USGS in Chile). Also the depth is fundamentally different in this initial phase (22 km USGS = dangerous and 40 km EMSC = less dangerous)

The earthquake took place in the border area of Southern Peru and Northern Chile.

Most important Earthquake Data:
Magnitude : 6.2 preliminary – 5.9 USGS  EMSC 6.4 – USGS 6.2
UTC Time :   Monday, May 14, 2012 at 10:00:30 UTC

Update 15/05 – 07:43 UTC :
- The landslide blocking the important road from the capital to the east of the country, has been cleared from debris. Service personnel from the government did the job together with the local people. 114 families were totally cut off of the outside world (they had no communication neither) during a number of days.
- The local press now talks about 2 fatalities. 1 person was crashed by a collapsing wall and a second person who perished because of a heart attack directly resulting from the earthquake.
- The region is still being hampered by aftershocks.
- Seismologists in Tajikistan have said that Tajikistan has an average of 3000 earthquakes per year, the great majority of them unnoticed by people.

Update 14/05 – 23:05 UTC :
- The important road which connects the central part of the country with the Eastern earthquake damaged part has been destroyed by a landslide over a distance of 150 meter. Experts and service personnel are working to make the road  passable again. The height of the landslide debris covering the road ranges from 4 to 6 meter!
- The BBC Russian news reporting 3 killed people has not been confirmed by any other news source so far.  Local and well informed Russian press is speaking about 1 killed person (also reported by us in the beginning).
- Sources close to the government have a new estimate of people made homeless : 6000!
- Tents have been send and pitched in some areas. Other areas could not be reached yet, making a clear picture of the earthquake devastation very incomplete

Epicenter area - image courtesy Sergey Bulanov

Important Update 10:00 UTC : 3 people have been killed.
Aftershocks are still occurring. Dozens have been injured and 2000 homeless have occurred.
The road connecting the Rasht Valley to the center of the country in several places has been blocked by landslides and rockfalls, hampering rescue work and complicating the delivery of humanitarian aid to affected areas.
Clearing the road will require heavy machinery. There are also no telephone services to the disaster area.
According to local authorities, the victims are in urgent need of medical and humanitarian aid.
The earthquake occurred at 04:30 local time. The epicenter of the shock was located at 152 kilometers southeast of Dushanbe, in the mountain region of Garm. According to the geophysical services, strong tremors were felt throughout the eastern region of the country.

Thousands of people are afraid to return home and try to stay on the street. People who have become homeless overnight, will spend the night in mosques, schools and homes of relatives. According to the deputy chairman of the Tavildara district, the earthquake left homeless villagers in need of tents, food and warm things.
The situation is complicated by the persistence of heavy rainfall and an incomplete damage picture.
Experts estimate the condition of many dwellings in the place of disaster and emergency as unfit for habitation.
“Looks like a blast”

“My family has remained practically on the street. My child was injured. People here are poor and cannot rebuild their homes. This is a tragedy. We spend the night on the street,” – said another local resident of Shokirjon.
The Garm group of districts is one of the poorest regions of the country with the highest percentage of unemployment in Tajikistan. Because of the distance from the center of Tajikistan and the lack of basic foodstuffs and essential commodities the cost is two times higher than in other regions of Tajikistan.
ER Remark : contrary to what is mentioned in this report, the current weather is OK. The heavy rainfall with floods as a consequence was from a couple of days ago.

Important Update 09:30 UTC : The Committee of Emergency Situations and Civil Defense of Tajikistan, by means of Mr. Nurov Nargis, has reported that 1 person, Mr. Tandovchi Jamoat, has been killed when a wall collapsed.
- The same agency reports that several houses have collapsed by the 7 intensity quake (epicenter).
- A landslide has further destroyed 2 houses and their ancillary buildings in the village of Kalai Surkh Jamoat Langaral Rasht. (source News.tj)
We will certainly receive more reports later today as this is an intermediate report.

Video : The “tripadvisor video” (in fact a series of pictures) below gives a better idea of the road which is mentioned in the above updates and 1 image of a village in the Tavildara district, the location of the epicenter. Sorry for the pictures from the snow leopard, but we cannot cut parts out of this video as we want to respect the copyright of the owner. The pictures are showing a rug landscape. The only villages shown at the end is build against the mountain slope. You will not need a lot of imagination to be convinced that a landslide can make huge damage.

Update 07:50 UTC :  While trying to find news from within Tajikistan, we could read that the Prime Minister has been visiting Kulob in the South of the country, where a couple of days ago, floods have destroyed a lot of houses, a lot of damage, but no fatalities.  Kulob is a city in the South-West of the country. The earthquake’s epicenter in the South-East.  A lot of rain in combination with earthquake shaking is a dangerous cocktail. The current weather in the area is fine. temperatures from 9 (min.) to 22 (Max.).

Update 07:21 UTC :  It is currently 12:21 in Tajikistan.  We are confident that eventual serious damage news may have reached the capital of Dushanbe in the meantime.  As the proverb says : no news = good news. Let us hope that the proverb is true.

Update 07:19 UTC :  Kyrgyzstan seismological sources are reporting that the intensity of the earthquake in the epicenter area was felt as 7.5 (on a scale of 0 to 12 – the scale is more or less similar than MMI). At the Kyrgyzstan side of the border intensity was 3.5.

Update 07:00 UTC :  So far we could not retrieve any added value info from inside Tajikistan. We haven’t found any damage or injuries which is a very good sign. Most reports are mentioning 1/10th of our report and are writing about a “moderate  earthquake”.  Specialized earthquake followers know that a shallow M5.7 earthquake from Turkey to China is in average not a “moderate ” earthquake but can be very dangerous .  In terms of Earthquake-Report.com, we are only convinced of the happy ending when we read direct news from de epicenter or from specialized emergency personnel. We call upon our Tajik readers to share their information with the ER readers.

Update 01:22 UTC :  Historic earthquakes in Tajikistan.
37 damaging earthquakes have been recorded so far within 100km of the present epicenter.
- 1934 and 1935 – damaging quakes quite close – about 20km away with damage in Tajikistan, province of Tovildera.
- 1949 – the magnitude 7.6 earthquake struck around 40km away in Khait, killing around 12000 people (7200-28000), nearly all due to landslides.
- 1983 – saw lots of damage in the Garm region from a M5.3 quake.
- In 2007, about 20km away 12 people were killed from a M5.2 quake – Three people killed in the Rasht region and nine killed in a related landslide in the Asht region. Felt at Dushanbe.
(CATDAT James Daniell information).

Update 01:02 UTC :  The epicenter area has an altitude of 2000 meters. The mountains in the greater area are more than 4000 meter high? We have printed a picture of the important valley where also  the M 41 highway passes.  The picture shows the kind of terrain where the earthquake occurred.

Focal Mechanism of this earthquake - Image courtesy USGS

Update 00:19 UTC :  WAPMERR, the theoretical earthquake damage calculation engine just reported that they are expecting 200 to 900 people to be injured and 30 to 200 fatalities.  The WAPMERR data are based on historical earthquakes in the area and on the reported USGS data (M5.7 at a depth of 10 km).
WAPMERR refers to 8000 people experiencing a MMI VIII severe shaking, 5000 people a very strong shaking, 15000 people a strong shaking and 135000 people a moderate MMI V shaking.

Update 00:19 UTC :  We do not expect to find a lot of news before 10 AM local time (about 5 hours from now) because of the remote mountainous area.

Update 00:19 UTC :  EMSC has further decreased the Magnitude from Mb6.0 to Mb5.7, a whole lot of difference. EMSC keeps his focal depth at 4 km which is extremely shallow. Because of the depth parameter, we maintain our opinion and continue to call this earthquake dangerous.

Update 00:12 UTC :
Less than 1000 people are living in a radius of 5 km from the epicenter
4,200 people are living within a radius if 10 km
11,000 people within a radius of 20 km.
Earthquake-Report.com calls a radius of 20 km at high risk for at least minor damage or minor injuries

Update 00:08 UTC : The nearest populated places are: Kalay-Khodzha (16km), Talbar (7km), Yezgan (7km), Tavildara (13km), Chil-Dara (17km). The closest civilian airport is Darwaz (46km).

Update 23:59 UTC : Based on the current data, Earthquake-Report.com calls this earthquake “dangerous” for the villages in the immediate vicinity of the epicenter. Especially the building style is very vulnerable.  An increasing danger factor is the fact that the earthquake occurred in the middle of the Tajik night!

Update 23:56 UTC : Following our own research Tavildara, a village with approx. 500 inhabitants is at a distance of 10 km from the epicenter. Ezgand another village is also very close to the epicenter

Shaking map of the area - courtesy USGS - Yellow color indicates the strong shaking area

Update 23:56 UTC : EMSC has changed depth again to 4 km (extremely shallow)

Update 23:50 UTC : EMSC has decreased the Magnitude to Mb6.0 at the new depth of  40 km. Data from USGS and EMSC are too different to be convincing.

Update 23:48 UTC : USGS reports a far lower Magnitude of 5.7 but at a depth of only 10 km.

Update 23:46 UTC : the epicenter seems to be located in the middle of the mountains apparently with very few villages.  We will search for more details.

An ER reader in Dushanbe (147 km from the epicenter) reported a moderate shaking.

Update 18/05 – 15:30 UTC :
Strong aftershock in Azerbaijan
Probably the second strongest aftershock so far after the M5.7 mainshock on May 7, 2012. Epicenter was also this time very close to Zagatala. The earthquake was felt as far as Tbilissi, Georgia.  We dot expect this aftershock to be very damaging, but minor damage on top of the already damaged houses is a real possibility. For earthquake details of this aftershock please click here.

At Earthquake-Report.com, we are once again irritated that almost nobody in the world has reported about this earthquake. 1 house cracked and a fallen chimney in a western capital seems to have more value than thousands of damaged houses in Azerbaijan. Selective reporting ? We have witnessed this situation over and over again and sometimes we feel the need to repeat it.

Update 10/05 – 08:59 UTC :
- Minister of Emergency Situations Kamaladdin Heydarov said to journalists on Thursday that the amount of money needed to repair and rebuild the damages communities may be higher than initially expected. If more money is needed, he said, more money will be reserved to accomplish this task.
- The number of earlier reported damaged constructions has increased considerably to 3123 (approx. 3000 houses and 123 state buildings like schools, social services etc). The assessment is continuing and the final outcome maybe even higher. A final count is expected within 3 or 4 days.
- Watching the degree of destruction in the villages, Earthquake-Report.com calls it a miracle that nobody was killed during this earthquake (although 1 newspaper was mentioning this without specifying any details). The number of injured is also very limited as we have counted 35 injured in total, but nobody serious. The most suitable explanation for the limited injured is that the earthquake occurred during the late morning hours when people are out of their houses.
- Medical staff and rescue teams are helping in the tented camps and are working in shifts to be present at all times.

Update 09/05 – 21:20 UTC :
- President Aliyev has visited today the earthquake damaged area. He met and talked with the homeless people. President Aliyev reiterated the relief effort of 20 million new Manats (24.5 million USD) in the initial phase in 2012, and the government has promised to rebuild and repair the area.
- The emergency services have started today with the repair and reconstruction of the hardest hit areas.
- Tents were distributed in the following villages : Zaqatala, Gözbarax, Zəyəm, Qımır, Çobankol, Bazar,  Qax, Güllü, Tasmalı, Ləkid, Zərnə and Lələpaşa.

A US person with friends in Azerbaijan reports :
The epicenter was in our close friends hometown- where her family still lives.  She went to visit yesterday and said that everything is destroyed.  Emergency services came, set up tents- and then left.  She wonders if they will do anything else, because they are only a village. Maybe only a village- but to the families there, this is everything.

Important Update 08/05 – 16:05 UTC :
- The Zaqatala district emergency commission chairman Mr. Elman Ramazanow has given more precise numbers on the damage of the double earthquake and aftershocks.  This is an intermediate report with data collected in more than 24 hours. Based on the limited area of the damage and our experience following earthquake events, we assume that these numbers may only increase slightly
- 274 houses, stables and other constructions have collapsed
- 2,052 houses have slight damage (cracks, partially collapsed walls etc)
- 100 social facilities  are showing cracks
- the emergency relief devision of the government has erected 500 tents  in a number of hard hit villages and 1,050 families have been allocated to these tenting camps. Another 500 tents will be erected today, which bring the total to 1,000.
- 1,276 families found temporarily shelter in the houses of relatives
- The central government of Azerbaijan has reserved 20 million Manat (24.5 million US$) for reconstruction aid

Update 08/05 – 13:12 UTC :
- some villages in the direct earthquake area remain without electricity
- government officials have told the press that rebuilding and repair of the damaged houses will start as soon as tomorrow

Update 08/05 – 08:47 UTC : The map below  gives an overview of both epicenters (M5.6 initial earthquake and M5.5 aftershock). The epicenters are the yellow bullets. The red bullets are the hardest hit localities (ie Muxax, Zəyəm, Çobankol, Bazar, Gözbarax). Most severely damaged villages are located in the foothills of the mountains. Zaqatala is in the upper left corner of the map.

Map created by Earthquake-Report.com

Update 08/05 – 07:24 UTC :
- Tents had to be erected as people cannot enter their damaged houses.  More than 300 people have been given a tent for this reason.
- It is currently raining very heavy in the earthquake area, which is an additional burden for SAR and relief personnel.  A lot of people who did fear aftershocks have spend the night in open air (Min. temperatures are about 10°C).
- Official communication goes by the Ministry of Emergencies led by Mr. Heydarov.  There are no official reports since yesterday noon about the number of hospitalized. Mr. Heydarov is currently visiting the earthquake area again and a new official press report can be expected soon.
- 35 people have been treated for minor injuries in hospitals and polyclinics and have been send home after receiving the proper treatment.
- Most of the damage was inflicted in approx. 20 villages in the Zaqatala district including Muxa, Zayam, Cobankol, Qımır, Mamrıx and Gozbarax
- Schools in the area have been closed until further notice.
- About 20 weaker aftershocks have been recorded in between midnight and 08:00 AM today.
- At the end of the month, the Eurovision songfestival will be held in Baku, the capital. The festival is extremely important for this country and the leaders as well as the population are proud to be the host. Azerbaijan did won the contest last year.  Baku is far away from the present earthquake epicenter and there is no reason to believe that any related strong earthquake will take place in this area, however it has to be said that also Baku is located in a greater fault area. On November 25, 2000 a Ms7.0 earthquake left 26 people dead . the epicenter of that quake was located 25 km to the South South East of Baku in the Caspian sea. 80 buildings were severely damaged. As a result of this earthquake, the Azeri authorities only allow new constructed buildings to have 9 floors.

Update 08/05 – 06:18 UTC :
- The village of Aliabad has been severely damaged. A lot of people in the most hit villages have spend the night in tents.

Update 18:17 UTC : Video from a local TV station showing the damage and interviews with a military responsible inspecting the damaged area and earthquake victims (Language Azerbaijan)

Update 17:34 UTC : 35 minutes ago a new M4.9 moderate aftershock struck the area. This is the 3th strongest today.

Update 17:28 UTC : The authorities have decided to supply tents to the homeless in Zaqatala, probably too late as the night has almost fallen.

Update 17:13 UTC : The damage and destruction are looking to be bigger than previously reported. In Zaqatala, at least 60 houses are seriously damaged. Most of them have collapsed walls. People are too afraid to return to their houses and will probably spend the night in the streets or in the fields.  We have heard no news of tents to give shelter to those living in the damaged houses or those wanting to stay away from their house. Most older buildings in the area are made of brick and are not earthquake resistant which increases the chance of damage or even destruction. For those who are not convinced that the damage is considerable, please take a look at the pictures of this Azerbaijan website.

Update 16:53 UTC : 2 people have been rescued by SAR teams from a seriously damaged  house in Gulbarax, this after the latest strong aftershock. Some injured have been taken for treatment to hospitals, but none of them was seriously injured. The strong aftershock is responsible for damage to some buildings in Zaqatala (Zagatala).

Update 15:20 UTC : Aftershocks are continuing to strike the area. Most of these aftershocks are only felt in the direct area of the epicenter. The weather outlook in the area can be called mixed. Temperatures are 11 (min) to 222 (max), but rain has been forecast for today and tomorrow.

This morning earthquake damage : 3 villages were the hardest hit with many older houses seriously damaged. The 3 villages are all located in the Zagatala area. From earlier reports we know that they are : Azar, Zayam and Gymyr. Luckily no fatalities though.

Update 15:16 UTC : Azerbaijan media are talking about a M5.3 earthquake with an intensity of MMI 6 to 6.5 (local scale which is comparable with the MMI scale). Both USGS and EMSC are reporting a 5.5 or 5.6 earthquake at a depth of approx. 11 km. Both agencies are locating the epicenter at 10 km from Zagatala versus 17 km this morning. Reports from our readers living in the greater earthquake area are somewhat conflicting. Some are talking about a short shaking which was considerably weaker than this morning, others are reporting higher “Felt it” values. We reiterate that Zagatala is an important regional city with 18,277 inhabitants.  A gas pipeline is crossing the area.

Update 15:02 UTC : 68,000 people are reported to have experienced a very strong shaking.  Earthquake-report.com does not think on many injured or fatalities because most people will have been staying on the streets as the area has been struck by tens of aftershocks since this morning. Potential damage is likely to have happened.
145,000 people will have felt a strong shaking. This mornings earthquake was reported as a max.  MMI VI (strong shaking) versus MMI VII this afternoon. As older houses were already damaged this morning, some unstable walls may have succumbed under the shaking.

Important Update 14:57 UTC : Another powerful earthquake (aftershock) occurred at 14:15 UTC. We are currently collecting more information. This earthquake looks even more dangerous than the first one as the epicenter is closer to Zagatala (preliminary data from USGS).

Example of the destruction during this earthquake - image courtesy APA

Update 13:25 UTC : From the time of the mainshock until this update, the epicenter area has been shaken by at least 80 aftershocks, a lot of them only recorded by instruments and not felt by the population.  The south side of the Caucasus ( including the Zagatala area) is known as a seismically active zone. The last massive earthquake in this area dates from 1936 when a Magnitude 7 earthquake struck the area

Update 10:55 UTC : Azerbaijan news agency APA reports that no problem was detected in the delivery of power, water, gas and communication in Zagatala. Roads in or near Zagatala were not disrupted. The International Bus Terminal told that buses move in direction of Zagatala in accordance with the schedule, no closures of any part of the motor way was recorded so far: ‘No problem is observed in arrival and departure of vehicles’.
Nearly 20 persons arrived at the hospital with different injuries, but none of them were operated or placed at the resuscitation ward. They were given first aid and sent home.
We remind our readers that this report focuses on Zagatala, very close to the epicenter, but not above the epicenter. We will need 4 to 8 hours more for a final update of the direct epicenter area.
More pictures of the damage can be found here.

Update 09:59 UTC :   According to the Seismological Service of the National Academy of Sciences of Azerbaijan, the Magnitude of the earthquake was 5.7 at a depth of 11 km. Following the same agency, the epicenter was located at 17 km from Zagatala (below also called Zaqatala). The gas pipeline linking Baku – Tbilisi and Ceyhan have not been affected by the earthquake

Update 09:15 UTC : From the Azerbaijani side of the border, there are reports of destroyed houses and at least 15 people have been treated for injuries so far, mainly due to panic while fleeing the houses. The hardest hit villages at the Azerbaijani side are Azar, Zayam and Gymyr

Update 09:06 UTC : Earthquake-Report.com also fears for damage and possibly injuries in the smaller mountain villages of the area, especially rockfall and landslides. These villages are only visited many hours after the earthquake.  Nobody has reported yet on the conditions right at the epicenter, as this area is populated too! It looks like farming soil with a couple of hundred houses (prevailing the preliminary epicenter location is right)

Update 08:43 UTC :  As we have feared, this earthquake tends to be more dangerous than the numbers would make out.  Local Georgia and Azerbaijani press reports are reporting not only damage in houses and schools (merely cracks) but also injured people. In the meantime aftershocks are terrorizing the local Caucasus population with so far at least 3 aftershocks above M4.

Yellow area : strong shaking) - greenish area : moderate shaking

Update 07:43 UTC :  Earthquake-Report.com fears that the damage as a result of this earthquake may be bigger than initially expected. In Georgia alone (EMSC and USGS are maintaining the epicenter in Azerbaijan) many houses have slight damage.  We expect more detailed news within 2 to 4 hours.
We will start an in-depth article as the results of this earthquake will be probably beyond the scope of this page.

Update 06:41 UTC :  Russian authorities are reporting a Magnitude of 5.8. The earthquake was also felt in Dagestan . People in the epicenter area have fled on the streets and remain there until further notice out of fear for aftershocks.

Update 05:41 UTC : Following other sources, the epicenter should be at the Georgian side of the border, 1 km from the village of Zemo Kedi and 22 kilometers from the city Dedoplistskaro (Kakheti region). 2 aftershocks are felt so far. The aftershocks are in the 4 to 5 range, enough to frighten the people from the epicenter area even more

154,000 people may have experienced a strong shaking, enough to create a damaging earthquake. Similar magnitude earthquakes had few fatalities, but we would not be surprised that damage is inflicted.
Closest communities are Zaqatala (pop. 18,277) and Cinarly (pop. 6,508).
EMSC reports a Magnitude of 5.5 at a depth of 10 km.
296,000 people have experienced a moderate shaking and nearly 3 million people a light shaking.
Cities who have experienced a strong shaking are : Aliabad (9000 people), Zaqatala (18277 people) and Qax (12000 people).
The area where the earthquake happened was a 3-country area. The epicenter is close to Russia and Georgia. Armenia is at a considerable distance
WAPMERR, an organization specialized in theoretical calculation of possible casualties reports, expects 5 to 40 people to be injured and 0 to 5 people to be killed. WAPMERR’s calculations are based on present and past data.

Update May 1, 2012 – 14:56 UTC
Strong aftershock in Sulawesi, Indonesia
Although the 5.5 Magnitude can be considered as strong in our terms, the depth is weakening the impact and we expect no serious damage or injuries . People in Sulawesi are experiencing a lot of earthquakes and their houses are build from material (mostly wood and bamboo) which is very efficient against earthquakes. Brick and concrete are mostly used in bigger cities only.  USGS expects 1000 people to have experienced a MMI VI strong shaking. 43,000 people a moderate shaking and 562,000 people a light shaking. The epicenter area is the same then last week Mw5.8 earthquake. Click here for our in-depth article. During this Mw5.8 earthquake, 51 houses were damaged and 2 people injured. Hypocenter depth was reported as 9.9 km versus 40 km today, a lot deeper and thus less dangerous.
Update : BMKG, the local Indonesian seismological agency reports a Magnitude of 5.3 at a depth of 10 km. The epicenter is following BMKG located offshore, a whole lot of difference. We trust BMKG as a very good seismological agency and in this case working with their own instruments (closest to the epicenter). See also our daily report of May 1

Lake Matano, Sulawesi, Indonesia greater earthquake area - Panoramio picture courtesy John Adamson -

UPDATE 16:30UTC: At least 16 houses have been damaged, 35 others have minor damage, and two people who were in Parliament House of the Morowali District, Central Sulawesi were injured by the earthquake that struck the area.

“We still continue to record the number of casualties and damaged buildings,” said Police Chief Adjunct Senior Commissioner Morowali Suhirman who called from Palu on her cell phone to news services in Indonesia.

According to him, the parliament building of Morowali suffered damage estimated at 35%. “There is no wall that collapsed, but cracks everywhere,” he said.

It is likely that the damage will exceed that of the M8.6 earthquake a week ago.

While the houses are severely damaged and collapsed generally cracked. Damaged buildings, mostly owned by people living in the District Bungku Central and Eastern Bungku.

This earthquake has been labelled CATDAT Orange.

UPDATE 05:00UTC: Our main concerns are still closer to the epicentre where we have no word yet.

Good news from a large town a moderate distance from the epicenter. Students taking their exams at SMA Negeri 1 Malili (80km away from the epicentre) rushed outside, with no injuries, but there appears to be no damage – therefore they have continued their exams.

UPDATE 03:30UTC: No news from the epicentral region as yet. Indonesian news services are repeating the epicentral location with no other information. We are currently trying to get news from the epicenter given the severity of the 15.02.2011 quake.

UPDATE 03:10UTC: There are numerous mines in the area. Three hydrodams power the residential area and the power was out for almost 48 hours in the last event in the region.

UPDATE 03:00UTC: BMKG has confirmed the severity of the earthquake with a Ml5.7 at 10km.

An earthquake in approximately the same location of Mw6.1 hit last year on the 15th February 2011, with damaging results. Although there were no casualties, some houses collapsed and many cracked.

“The Indonesian news channel Tempo reported that hundreds of people ran to the higher grounds of the Sorowako airport when the earthquake struck yesterday evening (local time) fearing for a lake tsunami. The local people told reporters that the shaking lasted for approx. 1 minute. Most people were enjoying dinner when the shaking started.
So far no casualties were reported. However, a dock on Lake Towuti vanished (probably by the shaking).
The first damage inspection survey in the greater epicenter area revealed that hundreds of houses are left with cracks in the wall, many school buildings area also damaged.
Some houses are reported collapsed in the Malili district, approx. 30 km from Sorowako.
Sorowako residents are still scared. Officials did inform local people not to believe in the rumors of a potential lake tsunami.”

We expect lesser damage than the M6.1 earthquake. Read more about the previous earthquake from last year here to get further insight into the region.

The earthquake was felt strongly in the epicentral region. Shakemaps are expecting a VII intensity, however from BMKG only intensity V.

The April 11, 2012, M8.6 and M8.2 earthquakes off the west coast of northern Sumatra, Indonesia, occurred as a result of strike-slip faulting within the oceanic lithosphere of the Indo-Australia plate. The quakes were located respectively 100 km and 200 km to the southwest of the major subduction zone that defines the plate boundary between the India/Australia and Sunda plates offshore Sumatra. At this location, the India/Australia plates move north-northeast with respect to the Sunda plate at a velocity of approximately 52 mm/yr.

Focal Mechanism of the Mw8.6 earthquake

Large strike-slip earthquakes are not unprecedented in the diffuse boundary region separating the India and Australia plates, southwest of the Sumatra subduction zone. Since the massive M 9.1 earthquake that ruptured a 1300 km long segment of the Sumatran mega-thrust plate boundary in December of 2004, three earlier large strike-slip events had occurred within 50 km of the first large April 11, 2012 event. These earthquakes occurred on April 19 2006 (Mw6.2), October 4 2007 (Mw6.2) and January 10, 2012 (Mw7.2).

The focal-mechanisms of the three earlier earthquakes and the two great earthquakes of April 11, 2012, are consistent in implying that each earthquake could have occurred as the result of left-lateral slip on a north-northeast striking fault or right-lateral slip on a west-northwest striking fault. The two different orientations of strike-slip faulting are both possible under the same tectonic stress field; perpendicular strike-slip faults that are both compatible with the same stress field are called “conjugate faults”.
Possibly faults of both orientation have been involved in the recent earthquake activity.

Image which we made on January 10 after a similar Mw7.2 earthquake occurred in the same area

In which countries was the earthquake felt ?
Felt in much of Sumatra, Malaysia, Singapore and Sri Lanki. Also felt in many countries as far out as Male, Maldives to the west,  Dacca, Bangladesh; Calcutta, India; Rangoon, Myanmar; Bangkok, Thailand and Ho Chi Minh City, Vietnam to the north.
Thirty one cm.  (peak-to-trough) tsunami at Meulaboh.

Update 13/04 – 16:04 UTC
A local Guaymas newsletter (Autónomo) reports damage to 2 schools and a house in Empalme. Empalme is more than 150 km from the epicenter !

Update 13/04 – 09:54 UTC
The staff of Civil Protection, Urban Infrastructure and SIUE (Ministry of Urban Infrastructure and Ecology) is conducting currently an inspection in the Guaymas area (150 km from the epicenter).
The local head of Civil Protection, Leon Gerardo Soto reported that home owners in the greater Guaymas area have calles the Civil Protection to report damage on their houses.
Regarding the City Hall (Palacio Municipal), he said that new cracks were found at the main entrance.

Palacia Municipal de Guaymas - Image courtesy english.realmexico.info

Update 21:12 UTC
* Cracks on walls in Guaymas, Sonora : People were calling newspapers and local media to report damages in their houses. El Palacio Municipal (Municipal Palace ,local government building) reported cracks on the principal entrance.
* Mexican Proteccion Civil has evacuated people from the beach as a precautionary measure

-  Update 17:17 UTC
* At least 60 Americans have asked their touring companies to be transferred away from their vacation location at Bahía de Kino.
* Proteccion Civil Mexico has reported that they have had NO reports of damage or injuries in Guerrero Negro.  One of the main reasons that this earthquake will have been harmless may have been the short duration of the shaking (10 seconds in Hermosilla)
- An ER reader living in Tucson, Arizona (USA) mentioned having felt the earthquake !

Strike-slip type of earthquakes

- Since the mainshock, the earthquake area has been hit by 6 aftershocks varying in strength in between M3.7 and M4.8.

- The earthquake was felt strongly. There have been 2 confirmed reports in San Luis of a VI intensity (72km from the epicenter). This means that there is the potential for VII-VIII in the epicentral area (damaging). (we are choosing to ignore a response of VII, which came 354km from the epicenter).

- Historic damaging earthquakes of similar magnitude have occurred once in the epicentral region with a M7.0 earthquake in 1954 causing no deaths and minor damage. This is a good sign for the region affected.

- Looking at the epicentral area – the location is very sparsely populated with only a few houses along the coastline apart from Santa Isabel.

- Mexican hypocenter (UNAM) is at M6.8 and 10km depth, under land.

- USGS hypocenter is at M6.9 and off the coast – there is little chance of a tsunami due to the fault mechanism.

- The area around Santa Isabel is most at risk from the USGS-based hypocenter with a possible shaking of VII. Some damage should be expected. Currently Agua de Soda and other towns closeby near the national park of Baja California are most at risk from the Mexican hypocenter which is below land.

- The Mexican Civil Defense who is responsible for Search and Rescue and first aid has reported that so far NO damage or injuries has  been recorded.

- Based on the Geofon data both earthquakes were strike-slip earthquakes (mainly lateral movement).

- The average shaking recorded in Hermosilla is MMI IV (based on 84 reports). The shaking in Guerrero Negro is MMI V (moderate).  Hermosillo is 10. km from the epicenter and Guerrero Negro 133 km. As explained before our attention goes to the immediate area of the epicenter (very shallow earthquake) – 30 to 40 km radius is at risk for eventual damage. Whether there will be damage or not will depend on how long both shakings have lasted and on the final earthquake data numbers.

- As the earthquake struck in a coastal area, NOAA has written in his latest report (for USA people mainly) : A strong earthquake has occurred, but a tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, or Alaska coast. NO tsunami warning, watch or advisory is in effect for these areas. Based on the earthquake magnitude, location and historic tsunami records, a damaging tsunami IS NOT expected along the California, Oregon, Washington, British Columbia, and Alaska coasts.

- So far we have no news of the epicentral area.

- The earthquake happened just after midnight. Mexican news channels haven’t picked up the news yet.  Of course it is in the middle of the night in Mexico and people seem to have been used to the many earthquakes of the last 24 hours.

- The set of earthquakes in the Gulf of California have started with a M4.7 earthquake, followed 18 minutes later by a M6.2 earthquake and another 9 minutes later with a M6.9 earthquake (the most powerful so far)

- USGS has calculated that 3000 people will have experienced a very strong shaking and that 105,000 have experienced a strong shaking. Both these areas are at risk for eventual damage, especially because 9 minutes earlier another very strong earthquake struck the same area.

- The Mexican Servico Sismologico Nacional reports a magnitude of 6.8 with an epicenter below land. These makes this earthquake the most dangerous in 24 hours !

- Although it is a ridge earthquake, the epicenter of the M6.9 quake looks to be very close to the coast which makes this earthquake (the second very strong in a matter of 9 minutes) EXTREMELY DANGEROUS for shaking damage and fatalities. Let us hope that we are too pessimistic here. The kind of shaking will depend on the focal mechanism

- Following calculations by the USGS (providing that the earthquake data are correct) a MMI VII will have been experienced on the Baja California peninsula ! This means dangerous for the coastal areas experiencing this kind of shaking.

- The whole North American continent is currently moving in such a way that the earthquakes of the last 12 hours are somehow related (Mexico Sur, Mexico Gulf of California, Utah, Oregon) . Scientists will have a lot of work in examining eventual relationships however there is no certainty at all that a relation would exist (at least for a couple of these earthquakes)

- We are talking in this case about a Ridge earthquake, this means 2 separating plates who are hanging and suddenly get away from each other. Ridge earthquakes are typical for Middle Ocean locations

- The earthquake struck just after midnight

- We are currently collecting data

Update 13/04 – 07:35 UTC
After searching authorities reports and news reports, we were unable to find any damage occurred because of this earthquake. We are however not sure about all this, as the epicenter center area is mainly a wilderness and rural area with only a few smaller roads. If anyone has knowledge of damage or injuries, please use one of the forms below to let us know.

Landscape in the greater epicenter area - image courtesy julyoboy82

On September 19 1985, a Magnitude 8 earthquake occurred at only 43 km from today’s epicenter. This earthquake was very cruel as it killed  approx. 9,500 people

- So far NO reports of damage or injuries. As the epicenter is located in a wilderness area with only a limited number of roads but with a limited agrarian community, we expect reports to ripple in after many hours. 

- EMSC maintains the Mw7.0 at a depth of 80 km for the moment, but we expect this to be changed for the USGS and Mexican data.

- We have just changed the title as USGS has been decreasing the depth to a dangerous 20 km. The new USGS data are somewhat confirmed by the local Servicio Sismologico Nacional who reports a Magnitude of 6.4 at 16 km depth.  The combination of Magnitude and depth can be a damaging cocktail. We expect a radius of max. 40 km at highest risk.  The new revised data will have generated a strong shaking for 15,000 people and a moderate MMI V shaking for 284,000 people.

- USGS has just downgraded the Michoacan earthquake from the initial Mw7.0 to Mw6.5. The depth however has been decreased further to 20 km, which makes the earthquake very dangerous for damage in the epicenter area.

- Our greatest fear is the danger for landslides in the area.  The terrain is very hilly as shows this Wikipedia description : The state is crossed by the Sierra Madre del Sur, the Trans-Mexican Volcanic Belt and the Inter-mountain Valleys region. The Sierra Madre del Sur crosses the state northwest to southeast for approximately 200 km in the southwest between the municipalities of Chinicuila and Arteagaalong the Pacific Coast. It is considered to be a continuation of the Sierra Madre Occidental. Peaks in this range average about 2,900 masl, with the largest being the Cerro de las Canoas. The Mexican Trans Volcanic Belt crosses the state from west to east toward the Toluca Valleyand Valley of Mexico. This mountain range is marked by appearance of many volcanoes, active, dormant, and extinct alike (ER: this is however an earthquake which will have no immediate impact on the volcanoes). This system is subdivided into regions such as the Sierra de Tancítaro, Sierra de Periban, Sierra de San Angel and others. The best known volcano in this region is the Paricutín volcano

- We do thank all the people in Mexico who have shared their experiences with our readers. Sharing information with each other is the best way of finding out what the extend of the earthquake is.

Shaking map courtesy USGS (based on Mw7.0)

- Scientists will have a hard time in explaining that there is NO relation in between the Oregon Mw5.9 earthquake and the M7.0 Mexico earthquake. There was a diffrence of 14 minutes in between the Oceanic Oregon earthquake and the Mexico subduction earthquake.

- USGS keeps his Magnitude Mw7.0 but has decreased the depth to 65 km instead of the initial 84 km.

- Today’s earthquake is of a completely different type than the massive March 20 earthquake. Also the epicenter area is in a different part of the country.

- There is of course NO tsunami danger as the earthquake occurred below land

- 637,000 people will have felt a strong shaking and 1,000 a very strong shaking!!

- There are angry people because earthquake alarms didn’t activated in some parts of the country.

- Power is off in some parts of Michoacan

- Update 23:28 UTC : Carlos Robles reports that :
* It was felt very strong at Lazaro Cardenas and strong in the center of Puebla.
* Alarms were activated before the earthquake and there were evacuations.
* Aftershock of 4.0M.
* As I have seen on live TV, communications are going down when they call to people at other cities.

- The Mexican seismological Agency reports a magnitude of 6.4. EMSC (Europe) report M7.0 at a depth of 80 km.

- Carlos Robles just reports that nor Oaxaco nor Mexico City did report damage. Earthquake-Report.com does not expect any damage neither

- This is a typical subduction earthquake where the Oceanic plate is subducting the North American plate.

- Lazaro Cardenas has a population of  178,817. Lazara Cardenas is approx. 69 km from the earthquake’s epicenter.

- This earthquake will be felt ALL OVER CENTRAL AMERICA because of the depth of the hypocenter.

- The first I Have Felt It reports are confirming the depth of the earthquake as only weak to very weak shaking is indicated

- Good news (if confirmed) – the earthquakes hypocenter is at a depth of approx. 80 km which will weaken the impact a lot

- Collecting news at the moment

The map below shows the output of the Surface Currents from Diagnostic (SCUD) model, an attempt to simulate where and how that debris would disperse. Orange and red shaded areas represent parcels of water with a high probably of containing floating debris. The deeper the red color, the higher the likely concentration. The debris field stretches roughly 5,000 kilometers by 2,000 kilometers across the North Pacific.

The model begins with more than 678,000 “tracers” being released from various points along the northeastern coast of Japan on March 11, 2011. The initial distribution is based on the density of population and development. The still image above shows the predicted distribution of debris by April 3, 2012.

The SCUD model was developed by Nikolai Maximenko and Jan Hafner of the International Pacific Research Center (IPRC) at the University of Hawaii. Using real satellite data on sea surface height and on ocean surface winds—as well as information from scientific drifting buoy networks—the IPRC team makes daily maps of surface currents. Hafner and Maximenko have also collected reports of debris sightings in the ocean, which have so far validated what the model tells them.

Debris was initially carried by the potent Kuroshio Current, which whips past eastern Japan much like the Gulf Stream in the North Atlantic. The Kuroshio carries surface waters northeast, before eventually turning east in the Kuroshio Extension and then the North Pacific Current. Some debris should reach the west coast of North America within a year or two, while much of it is likely to end up in the floating debris field in the middle of the North Pacific Gyre that is referred to as “the garbage patch.”

As of April 3, 2012, there had been very few reports of debris at Midway Island and Kure Atoll. North winds have been minimal in recent months, and ocean currents have favored keeping the debris from the island. But those currents may be shifting, Hafner noted, and debris should eventually wash up with greater frequency.

Observers in Canada recently detected an abandoned 150-foot Japanese fishing vessel floating offshore of British Columbia. Other reports of debris in Washington and Hawaii came in months ago. But in most cases, the objects were larger and standing above the water line, where they could be pushed like sails at higher speeds. The model shown above tracks objects sitting at or just below the water line.

Update 13/04 – 13:32 UTC
2 serious aftershocks in Guerrero / Oaxaca, Mexico
As predicted several weeks ago, the M7.6 earthquake in Guerrero Mexico would surely lead to a lot of aftershocks including some stronger ones which will be close or greater than M6.0. What happened today (M5.4 at 10:10 UTC and M5.3 at 13:06 UTC) could be expected and will normally not cause any additional damage. Let us hope that the aftershocks will gradually winding down in strength and number.

The damaged cathedral of Asuncion de Maria at Chilpancingo

Update 03/04/2012 – 17:49 UTC :
As we are constantly monitoring the local situation, ER contributor Carlos Robles reports that yesterday’s aftershock caused light damage in Chilpancingo. The city of Chilpancingo reports damage at the cathedral of Asuncion de Maria that was damaged by the previous earthquake. Other places also suffered damage like construction zones and a mall.

Update 03/04/2012 – 16:11 UTC : 
We are happy to report that we could not find any trace of serious damage or injuries after this earthquake.
- the early alert system in Oaxaco (SASO) has gone off seconds before the tremor could be felt. At earthquake-report.com we think that this kind of early alarms is only giving a false sign of security if the epicenter is below land.  In case of a very powerful earthquake which may be damaging in a radius of 100 to 150 km, the damaging shear wave will be arriving within seconds. People might try to evacuate in the meantime leaving a far better location for an emergency pathway.  A lot of them will be located in the stairway of apartment and office blocks, being at the most vulnerable place of the building.
Is there no real advantage at an early alarm ? : oh yes, to bring elevators to an emergency stop, trains and subway  emergency stops etc. and to warn for possible tsunami waves if the epicenter is out in the sea.  People in Guerrero have the final word in this case.
We see almost continuously infringements against the safety rule number 1 : drop, cover and hold.  Click here for our in-depth article and how to behave during and after an earthquake.
- A lot of tourists have not even felt the earthquake in Acapulco
- In Tlaxcala NO damage had been reported
- In Guerrero, 12,000 houses were seriously damaged during the March 20 mainshock. 2,400 houses will have to be reconstructed completely.  The other houses are partially damaged.
- The National Fund for Natural Disasters (Fonden) will help the families in Guerrero

Pager map courtesy USGS - dark orange : severe shaking, yellow : very strong shaking

Update 23:58 UTC :  USGS has again updated the earthquake data.  The (probably) final values are M6.0 at a depth of 9.1 km. These values are far better and less dangerous than their previous calculations.  With the new data, there might be a possibility that almost no damage will be inflicted. So far NO reports of damage or injuries
- the area is hit by numerous aftershocks in the M4 to M5 range

Update 20:28 UTC :  The authorities in Puebla, one of the major Mexican cities and approx. 250 km from the epicenter,  have reported NO injures or damage. Good news which we expected at this distance.
Earthquake-report.com calls an area with a radius of about 35 km around the epicenter at high risk for additional damage (to the already damaged houses during the March 20 mainshock).

Update 19:44 UTC :  USGS has increased his intensity mapping prediction. The new estimate mention 17,000 people having felt a severe MMI VIII shaking (damaging environment), 180,000 people a VII MMI very strong shaking.
The new values are bad news and will make this aftershock almost certain a damaging one.
Until now we have No details yet on damage and injuries. As said earlier it will take another 2 to 6 hours to have see first serious assessments of the epicenter area

Update 19:42 UTC :  Intensity report in the most important cities in the greater epicenter area :
VII    Cuajinicuilapa    9,000 people
VII    San Juan Cacahuatepec    4,000  people
VII    Ometepec    18,000  people
VII    San Pedro Amuzgos    4,000  people
VI    San Pedro Jicayan    4,000  people
VI    Santiago Pinotepa Nacional    26,000  people
MMI VII : very strong shaking
MMI VI : strong shaking

Update 19:16 UTC :  Mexican authorities are reporting the strongest shaking in the Costa Chica region. Until now, we have no reports of damage, but we are almost sure that they will appear in 4 to 8 hours.

Update 18:38 UTC :  Helicopters were dispatched 5 MINUTES after the earthquake. The only damage seen was a billboard that fall causing NO injuries. (we are confirming the very swift reaction of the authorities in DF)

Update :  The Mexican seismological agency has increased his initial Magnitude to 6.0. Since the mainshock today, 2 aftershocks of resp. 4.6 and 4.7 have been listed (normal)

Update :  Read also the many felt reports at the bottom of this page

Update 18:29 UTC :  Last time, damage was only reported after several hours or even a couple of days in the epicenter area (one of the poorest areas in Mexico). Most houses are made from brick or in adobe in the greater epicenter area.

Update:
- Security secretary of Mexico City reports that there is NO damage.
- Communications are still working.
- Subway is still working.
Such reports are mostly based on the capital Mexico City or DF.

Update :  Intermediate report from Carlos Robles : Servicio Sismologico Nacional is upgrading the earthquake to 6.0. Saldo blanco (no deaths) is reported. There aren’t reports of damage.

Update 18:23 UTC :  There are NO Nuclear plants or Hydrodams in the greater epicenter area

Update :  EMSC (Seismology Europe) reports now a magnitude of 6.1 at a depth of 10 km

Update 18:18 UTC :  NO tsunami danger as the epicenter of the earthquake is below the Mexican mainland

Update :  Evacuation were held at Mexico city.It was felt strong in some parts of Mexico city.In Coyoacan there are only reports of scared people. (source : Carlos Robles)

I Have Felt It map courtesy USGS - blue lighter, yellow strong shaking

Update : USGS predicts a very strong shaking for 3,000 people in the epicentral area. 164,000 people will have experienced a strong MMI VI shaking and 289,000 people a moderate shaking. As this earthquake is also felt in DF,  the earthquake will have been noticed by millions of people.

Update : As this is an aftershock from the March 20 M 7.4 earthquake,  these aftershocks, even at the current magnitude are very normal !

Update : The president of DF is flying by helicopter over DF areas to overview the situation. He reports that so far no serious damage can be seen from the air

Update : The Mexican media including the local seismological agency are not reachable because of too many connections

Update : The mainshock, which happened at March 20 was the 4th deadly earthquake this year

Update : 27 km (17 miles) SSE (148°) from Ometepec, Guerrero, Mexico

This aftershock can further damage already damaged houses in Guerreo
Epicenter also in Ometepec
EMSC reports a Magnitude of 5.7 at a depth of 40 km (preliminary)µ
The earthquake has been felt as far as Mexico City DF
Based on our experience we expect further damage in Guerrero but no damage elsewhere in the country
We will start an in-depth article soon as USGS is reporting a magnitude of 6.3 at the very shallow depth of 12 km. Potentially very damaging

Mexico DF - I felt it more than the March one but my colleagues didn't. Mexico City - a very noticeable shaking cicle-motion that lasted about 30 secs. not damages in mid-area of the City. Mexico City - A thump, rocking with the lamps swinging Reforma DF - on the 13th floor and building swayed for about 1 minute. not as bad as March Mexico City - I'm on 3rd floor in a corporate building in Mexico City (Reforma Street), it felt strong. Mexico - Secousses faisant grincer le bâtiment ( 18e étage) tout le mobilier vibrait, tremblait. Mexico DF - A good shake and feeling lots of aftershocks. MEXICO - We are on the 4th floor of an apartment in Mexico City and felt the swaying for approximately 30 seconds Mexico - I was in the bathroom washing my hands and I felt it was shaking, I thought it was only me but after that I saw the blinds swinging, doors were also moving back and forth.. Mexico City - I was walking around my home while the phone rang it was my sister asking me why didn't you go out of your apartment, we are having an earthquake now, I saw the lamps and they were swinging, I felt a moderate shaking, this time I didn't scared, because I hadn't notice what was happening. Thanks God nothing serious happened in Mexico city. I hope nothing serious happen in Mexico. Cuernacava - I'm near Cuernavaca, it shock around 30 seconds no damage. Mexico City - Foreigner living in Mexico. Not used to Earthquakes. This was my third one and I experienced it nine stories up. The sensation felt in the building was that of a boat in rough seas. The building swayed strongly. Mexico City - Moderate shaking indicated
