Displaced people : 458392
Max. tsunami level : 175 cm
Update 22:34 UTC: The Mexican authorities have increased the number of fatalities from 90 to 96 earlier today. The promised Mexican aid to Texas was canceled to cope with the own Mexican disasters.
Update 21:30 UTC: Some more info about the M5.5 aftershock off the coast of Chiapas, Click here
Update 16:46 UTC: This picture gives an idea of how difficult rescue and SAR missions are after an earthquake. Our greatest support goes to these people who are often risking their life as any moment a powerful aftershock can also put them in danger.
Update 09:18 UTC: Amazing solidarity from the people of Mexico-City towards the affected victims of the earthquake. So far no less than 32.5 tons of aid goods have been donated by the people. Mexico breaths solidarity. Congratulations
Update 08:30 UTC: Devastation and solidarity on 1 picture
Update 08:25 UTC: The maximum Tsunami level we could track was 1.75 meter
Update 08:24 UTC: As far as we could find out, at least 70,219 have been displaced.
Update 08:22 UTC: The Mexican government has reported that approx. 2.3 million Mexicans have been affected by the M8.1 earthquake. In the State of Oaxaca already 800,000!
Update 08:17 UTC: IRC has so far distributed 40 tons of aid goods to those suffering the most
Update Monday 08:16 UTC: The government reported that a very important number of schools and infrastructure sustained damage to different levels during the 8.1 earthquake and powerful aftershocks.
Update 07:13 UTC: Sad to report the further increase of the number of fatalities
Update 07:12 UTC: a fierce M5.7 aftershock was felt in the already seriously damaged region
Update 16:09 UTC: Mexican President, Enrique Peña Nieto, has called 3 days of National mourning for the victims of the earthquake.
Update 16:00 UTC: Rumors are starting to live their own life again. The risk for another M8 should be very high! The risk for a missive earthquake along the Mexican Coast is ALWAYS very high. Be prepared as much as possible that's the key to your safety and your house and belongings.
The only thing scientists can at the moment is where underground stress is accumulating.
NOBODY on the planet can predict an earthquake at this moment. NOBODY knows where it will strike, NOBODY knows the Magnitude it will have and NOBODY knows when it will happen.
Update 15:58 UTC: The aftershocks are somewhat weakening. Lees M5+ aftershocks, now more in the M4 to M4.5 range.
Update 06:34 UTC: This earthquake has a terrible aftershock pattern. Even with our Magnitude selector at 4, the android Earthquake Reporter app, sounds frequently! In real live this must be especially irritating. Most of the M5+ aftershocks will be felt in the coastal region.
Update September 9, 06:26 UTC: Mexican President, Enrique Peña Nieto, went to the hardest hit city Juchitán de Zaragoza in Oaxaca (35 people killed) to pay his respect to the deceased and to support the local people in these difficult times
Update 23:21 UTC: Another SAD update. Couple of minutes after this update we had to add 3 more people 🙁
Update 23:15 UTC: Finally ....

Update 18:32 UTC: The ultimate explanatory earthquake poster from this earthquake comes from geologist Dr. Jay Patton. Click on the image to be linked to his site. The poster contains lots of important scientific information and can be viewed in full format in his site
Update 17:55 UTC: Amazing video of short-circuits of power lines while the shaking was going on
Update 17:52 UTC: 90% of the power supply has been restored says @CFEmx
Update 17:14 UTC: We are using this occasion to show you a very interesting video of the M8.1 1985 Guerrero / Mexico City earthquake.
Reason to show it is the very good educational content of this video
Update 16:06 UTC: Sadly enough a further increase in the death count :(((
The injured count is only correct for Guatemala. We have not found to be trusted numbers for Mexico. In such a case we wait for the official numbers.
Update 16:05 UTC: At least 190 aftershocks have been counted so far. Our listings only mention the moderate to strong ones.
Update 16:02 UTC: The fatalities count in Chiapas increased from 7 to 8
Update 15:57 UTC: Professor Max Wyss, who specializes in theoretical prognoses of injuries and fatalities revised his initial numbers after using updated seismic data : Now he reports : 10 to 300 fatalities and 400 to 3000 injured people.
Update 15:48 UTC: Tsunami waves related to M8+ Chiapas #earthquake reached Galapagos Islands, #Ecuador, w/ small amplitude (<50 cm) (Via Stéphane Baize @stef92320)
Update 14:30 UTC: The fatalities toll further increased to 33 people (32 in Mexico and 1 in Guatemala)
Update 14:39 UTC: Guatemala update
Update 13:55 UTC: powerful aftershocks keep banging the Mexican coast 🙁
We did count at least 8 M5+ aftershocks (most of them at different distances out of the coast)
Update 13:45 UTC: A girl is begging for help :((((
Update 13:42 UTC: Astonishing picture of shaking damage
Update 12:15 UTC: Maximal tsunami heights as measured at 10:55 UTC. Max was measured at Salina Cruz (1.01 meter or 3.3 ft)
Update 12:13 UTC: Guatemala cancels the Tsunami alert

Update 10:18 UTC: Seismologists believe that the earthquake occurred in a potential seismic gap.
Definition of a seismic gap (John F. Cassidy) : The seismic gap theory (for a summary of early work in this field see McCann et al., 1979) states that a segment of a plate boundary that has not ruptured recently has the greatest chance of rupturing in the future (relative to other segments that have experienced large earthquakes). This is based on the recognition that tectonic plates move relative to one another at an approximately constant speed and the assumption that the slip of plate boundary faults occurs primarily during major (magnitude 7 or greater) earthquakes.
Update 10:07 UTC: All our Mexico mainshock and aftershock reporting will be on this page (aftershocks in the table below)
Update 10:05 UTC: Updated preliminary toll fatalities and injured people as compiled by EID
Update 09:52 UTC: Civil Protection agency Conred, Guatemala, says at least 24 houses destroyed, 85 people displaced in Guatemala (preliminary report)
Update 09:43 UTC: Continuing aftershocks in the greater epicenter area. Some are felt on the coastal states others have an epicenter to far from the coast.
Update 09:27 UTC: CATnews (CDIM Karlsruhe) Tsunami map
Update 09:01 UTC: 50 million Mexicans may have felt the M8.1 earthquake says the Mexican President, Enrique Peña Nieto
Update 08:55 UTC: Revised list of school suspension classes -
- Chiapas - Oaxaca - Hidalgo - Veracruz - Puebla - Tlaxcala - Tabasco - CDMX - Edomex - Guerrero - Morelos
Update 08:38 UTC: The Mexican President, Enrique Peña Nieto, is now at the @CENAPRED tot be kept informed about the situation in the country after the M8.1 earthquake
Update 08:32 UTC: Due to the deeper hypocenter the current tsunami measurements are after all to be called reasonable maximum 0.75 m (as far as we could trace it)
Schools are suspended until further notice in the states of Ciudad México, Chiapas, Guerrero, Veracruz and Guajaca.
Update 08:25 UTC: The current number of fatalities as compiled by the "Earthquake Impact Database"
Update 08:09 UTC: revised tsunami map and theoretical tsunami heights based on the deeper hypocenter (33 km to 69 km)
Update 07:59 UTC: two children were killed in Tabasco, a third victim in Chiapas and 1 in Guatemala brings the total to 6 :((
Update 07:58 UTC: people are sitting in the streets because of the fear for aftershocks
Update 07:54 UTC: More damage images via @Canal6Nicaragua
Update 07:50 UTC: no words needed
Update 07:38 UTC: The real damage impact from this quake (we expect it to be widespread) will only be visible in 3 to 5 hours at daylight.
Update 07:37 UTC: Based on the USGS theoretical expectations 23000 people have experienced a violent shaking.
Update 07:34 UTC: We are sad to report that at least 3 people have been killed by this earthquake. 2 others were injured in Mexico City. This is an intermediate toll which will increase considerably.
Update 07:25 UTC: USGS has revised the depth of the hypocenter to 69 km considerably decreasing the tsunami potential of the earthquake. Our earlier reporting that the source of the earthquake will be an intra-oceanic plate rupture is by this confirmed. A typical subduction earthquake at the point where the oceanic plates and Nort American plate meet would have generated a far more powerful tsunami and shaking. Nevertheless we expect a lot of damage and even at this depth the buoy's are showing some important ocean level changes
Update 07:22 UTC: Professor Max Wyss, who specializes in theoretical prognoses of injuries and fatalities expects : 0 to 20 fatalities and 90 to 800 injured people
Update 07:18 UTC: fierce shaking of the street lights
Update 07:14 UTC: A first grim picture of the damage in Chiapas! (image courtesy ElPoderTV
Update 07:13 UTC: shaking images at the offices of El Poder TV
Update 07:10 UTC: Most of the Pacific Islands have Tsunami advisories in place
Update 07:08 UTC: Tsunami waves are confirmed by a buoy off the Mexican coast
Update 06:57 UTC: First image of substantial shaking damage in Chiapas Mexico (image courtesy El Heraldo de Mexico)
Update 06:52 UTC: Shaking map with possible related damage from the natural disaster specialists at CATnews (Risklayer - CEDIM), Karlsruhe, Germany. Map generated by Andreas Schäfer.
Update 06:50 UTC: Multiple M5+ aftershocks but most of them off the coast (in the epicenter area of the M8.2 earthquake) so no harm for the coastal areas
Update 06:46 UTC: Main earth movement based on the current focal mechanism. Image courtesy Observatoire Geoscope.
Update 06:45 UTC: sources also show M8.0 Mexico quake is normal faulting, indicating "slab-breaking" event within subducting plate, not interface thrust
Update 06:38 UTC: The American NOAA tsunami system indicates tsunami waves up to 3 meters for Mexico! When you are living in coastal area of the islands of the Pacific, Central America, Northern part of South America and the United states please follow your local alert guidelines + check the specialized Tsunami bulletins at NOAA
Update 06:29 UTC: GDACS Tsunami simulation. Theoretical tsunami levels upto 1.1 meter. Coastal areas are at risk.
Update 06:22 UTC: HIGH Tsunami risk for all Central American countries
