Earthquake near Mount Fuji, Shizuoka brings additional insured losses of about $500 million

UPDATE 18/03 - 06:36 UTC :
With the minor nature of damage, it is unlikely that the economic losses from this earthquake will reach $500 million USD as calculated by EQECAT (a major EQ Modelling company). A lower value is envisaged, however with lack of data on this earthquake, no definitive value has been given. Luckily, no deaths!

UPDATE 17/03 - 12:18 UTC :
The total casualty toll is as follows: 2 serious injuries and 48 minor injuries.
Two seriously injured in Shizuoka City, Aoi-ku man (78 years old) broke his back falling from a window of their home. Shimizu-ku man (35 years old) broke his right foot after becoming trapped while working at the factory parts.
Some 521 buildings were damaged in 7 cities and towns. In Fujinomiya city, 287 houses had damage such as cracks and fallen tiles. Up to 518 people voluntarily evacuated. In Fujinomiya, 400 people were have evacuated, 118 people in Fuji city and in temporary shelters such as school and other shelter area. 20,000 households lost power. 21,700 households lost power shortly after the earthquake in the north around Fujinomiya. All recovered shortly. The water outage in the city occurred to 503 units.

UPDATE 17/03 - 09:45 UTC : EQECAT has estimated that the magnitude 6.2 earthquake that struck Tuesday south of Mount Fuji, Japan, likely will result in insured losses of about $500 million. About half of that insured loss likely would be ceded to the state-backed Japan Earthquake Reinsurance Co. Ltd. pool. It is unclear as to whether Tuesday's earthquake is associated with volcanic activity at Mount Fuji, the modeling firm said.

UPDATE 17/03 - 09:40 UTC : The number of injured people has increased to 33.
2 people have been treated for serious injuries, 31 for light injuries.

UPDATE 11:05 UTC :
Shizuoka earthquake injured 27 people
Fujinomiya observed in JMA 6, the other was taken to hospital with broken leg 57-year-old woman, in hospital and 15 people off their feet along the broken glass in 42-year-old man received attention. In Gotemba, JMA 5, debris fell on a 34-year-old man, struck on the head with minor injuries. In addition, in Shima Itizou, a 17 year old woman broke teeth in Shizuoka Prefecture fell from the stairs of her home and joined a list of injured with 27 people in the city and seven towns.
There were a few collapses in various places. In some districts of the city of Fujinomiya and Fuji is a temporary water outage, and some households, with power outages.

UPDATE 19:42 UTC :
The PAGER model comes out at between $10-100 million damage, however they say the most likelihood is of no fatalities.

UPDATE 19:39 UTC :
CATDAT records the following earthquake in late October, 1707. Tsunami 25.7 m high at Kure, Kochi Prefecture. More than 29,000 houses in total wrecked and washed away and about 30,000 deaths. In Tosa, 11,170 houses washed away and 18,441 persons drowned. About 700 drowned and 603 houses washed away in Osaka. 20 m high at Tanezaki, Tosa, 6.58 at Muroto. Hot springs at Yunomine, Sanji, Ryujin, Seto-Kanayana (Kii) and Dogo (Iyo,145 days) stopped. Kizumi described it as the largest earthquake in history.

Less than 2 months later the following happened:-

The last recorded eruption of Fuji was the Hōei eruption which started on December 16, 1707 and ended about January 1, 1708 (Hōei 4, 9th day of the 12th month) during the Edo period.
The eruption formed a new crater and a second peak (named Hōei-zan after the Hoei era) halfway down its side. Fuji spewed cinders and ash which fell like rain in Izu, Kai, Sagami, and Musashi.

Major earthquakes like the Sendai M9.1 earthquake, create massive stress transfer and may inadvertantly trigger other earthquakes on other faults or volcanoes. This may be the case in Japan this time.

UPDATE 17:51 UTC : USGS has updated the magnitude and depth of this earthquake to 6.2 at a depth of 10 km (originally 6.0 and 2 km)

UPDATE 17:31 UTC : The Fujinomiya earthquake occurred on a transform faulting zone which is indirectly interconnected with the Subduction fault zone in the Pacific Ocean which lies at the origin of the March 11 earthquake.

UPDATE 17:05 UTC : FDMA reported intensities :
Intensity 6 upper Shizuoka: Fujinomiya
Intensity 5 upper Yamanashi: Oshino Village, Yamanaka, Fujikawaguchiko Town
Intensity 5 lower in Kanagawa Prefecture: Odawara City, Kita Matiyama
Yamanashi Prefecture: City Minobu, Minami Alps City, Town Misato Ichikawa Fujiyoshida
Shizuoka: Fuji City, Gotemba, Oyama

UPDATE 16:32 UTC : On January 16, 1995 an earthquake at 345 km from the present location measuring 6.0 magnitude, killed 5,502 people.

UPDATE 16:25 UTC : Pager data from USGS are stating that 240,000 people in Fuki and 122,000 people in Fujinomiya have experienced a VII MMI very strong shaking.

UPDATE 16:18 UTC : GDACS published a GREEN earthquake alert for this earthquake = very limited chance on damage and/or injuries.
Earthquake-Report does however not agree with GDACS on this earthquake. All JMA seismological data are predicting at least injured people and damage.

UPDATE 16:11 UTC : As the epicenter of this earthquake is below Honshu, the NO risk for a tsunami. If rumors persist for the danger of a tsunami, please tell these people that there NO risk at all.

UPDATE 16:00 UTC : The locations which are most at risk having experienced a 6 or 6+ shaking (on a scale of 7!) :
6+Fujinomiya-shi Yumizawacho,  Fujinomiya-shi Nonaka
5+Oshino-mura Shibokusa*, Yamanakako-mura Yamanaka*, Fuji-kawaguchiko-machi Nagahama*

UPDATE 15:55 UTC : The first wounded people have arrived in the hospital. First reports are also mentioning damage.

UPDATE 15:52 UTC : The area around the Fujiyama mountain is without power.

UPDATE 15:46 UTC : The epicenter is located approx. 10 km from the city of Fujinomiya. The area surrounding Mt. Fijiyama is heavily populated.

UPDATE 15:38 UTC : This are the JMA seismologic data (Japan Seismological Service) : Magnitude : 6.0 Depth 10 km Epicenter location : Click here to see the map.
JMA is a very reliable data provider.

UPDATE 15:24 UTC : Earthquake-Report expects that this earthquake will also generate damage and casualties in Shizuoka prefecture and especially in the town of Fujinomya

UPDATE 15:21 UTC : Japan Meteorological Agency says the quake with an intensity of 6 plus on the Japanese seismic scale zero to 7.
6 plus is the same Felt scale as predicted during the March 11 earthquake. This JMA Felt prediction is extremely troubling.

UPDATE 15:12 UTC : This earthquake occurred in a totally different faulting zone than the tsunami earthquake which had an epicenter in the Pacific Ocean 170 km from the coast.

UPDATE 15:04 UTC : This is the first very strong earthquake below Honshu since the March 11 massive Earthquake / Tsunami.

UPDATE 15:03 UTC : This kind of earthquakes have merely a local damaging capability.

This very dangerous shallow earthquake occurred in the Japanese nightly hours at a close distance from Mount Fujiyama and at very close distance from the town of Fujinomiya.
The earthquake was so powerful that is was felt until Tokyo (Tokyo is at a distance of 116 km).
A few days ago warned for the influence of the megatrust quake on other fault zones in Japan. Earthquakes with a +6 magnitude below Honshu are rather exceptional. We have to call this an earthquake and not an aftershock as many will think.

Most important Earthquake Data:
Magnitude : 6.1
UTC time : Tuesday, March 15, 2011 at 13:31:46 UTC

  1. The more u know about the whole Earth, it becomes even more amazing how stable the water, land and air are most of the time. My friend John Young, lunar astronaut, believes in orbital, trans-lunar, lunar and Mars habitats for survival of our species in case of Earthwide mega disasters. Japan's nuke situation seems to be still deteriorating. Are there really 600,000 fuel rods available for meltdown? Time to get milk out of your diet for a while? Move to the southern hemisphere? Lets hope they can kill their/GE nuclear godzill. (Interesting as I write this the Hawaii tsunami warning siren 1st of the month test turned on!) I here prediction that if/when Fuji erupts it could signal a collapse of Japans east coast causing 1000' Pacific tsunami, wiping out US West Coasts. There have been over 850 quakes in the offshore Sendai vicinity since the Sendai 9.1 earthquake and tsumani event.

    Well, I just asked on Facebook if Fujiyama might erupt again and when was the last time. There's the answer above. Also, there was an earthquake there today of a different origin than the recent huge one with tsumani. Also above is info about the tsunami a day or so ago that the people were being warned about but did not seem to show up after all. Very useful. Thanks.
