Shimane Nuclear Power Plant [35.538°N, 132.999°E]

The event occurred about 50 kms from the NPP [Shutdown after Fukushima.] A previously unknown geological fault was discovered close to the Shimane Nuclear Power Plant in 2006, according to reports.

The quake was felt throughout 14 prefectures: Shimane, Tottori, Okayama, Hiroshima, Ehime, Hyogo, Kagawa, Kochi, Shiga, Kyoto, Osaka, Tokushima, Nara, and Wakayama.

Japan Region Earthquakes: Currently Valid Forecasts by FIRE-EARTH

A Note to Seismologists at Tokyo University and Tohoku University, Japan

FIRE-EARTH MODERATORS STRONGLY URGE YOU TO PRODUCE  ORIGINAL RESEARCH AND REFRAIN FROM PIGGYBACK RIDING ON OUR FORECASTS.

ONCE AGAIN, YOU HAVE MADE US EXTREMELY RELUCTANT TO POST ANY FUTURE EARTHQUAKE FORECAST.

Staff at Research Center for Prediction of Earthquakes & Volcanic Eruptions, Graduate School of Science, Tohoku University are strongly advised to focus on probability of the next major earthquake in China.

70% chance of big Tokyo earthquake ‘within 4 yrs’

The Yomiuri Shimbun —  There is a 70 percent probability the Tokyo metropolitan area will be hit directly by a strong earthquake of magnitude-7 level within four years, according to data compiled by a University of Tokyo research team.

The preliminary calculations conducted by a team from the university’s Earthquake Research Institute were based on intensified seismic activity in the area after the Great East Japan Earthquake on March 11.

The findings are more dire than a similar estimate by the central government’s Headquarters for Earthquake Research Promotion, which states there is a 70 percent chance a quake of the same scale will hit the southern Kanto region, including the metropolitan area, within 30 years.

The central government’s Central Disaster Management Council assumes 18 different hypocenters of magnitude-7 level earthquakes, such as in southern Ibaraki Prefecture and the Tachikawa fault zone.

If a magnitude-7.3 earthquake occurs directly under northern Tokyo Bay, as many as 11,000 people are expected to die and about 850,000 buildings to be rendered totally unusable or destroyed by fire.

According to the Meteorological Agency’s observations, after the March 11 disaster, earthquakes of magnitude 3 to 6 occurred an average of 1.48 times a day in the metropolitan area through December. This was about five times the pre-disaster average.

Prof. Naoshi Hirata of the university’s research institute and others based their calculations on the rule of thumb that the frequency of earthquakes is inversely proportional to their strength. For every increase in magnitude of one, the frequency of their occurrence falls by 90 percent.

The metropolitan area was hit by the magnitude-8 level Great Kanto Earthquake in 1923. Five weaker but still serious earthquakes of magnitude-7 level also hit an area extending from southern Ibaraki Prefecture to the Uraga Channel over a period of about 120 years.

The government’s earthquake headquarters obtained its quake estimate data based on the intervals of these quakes in the past. The data did not incorporate the increased seismic activity after the March 11 disaster.

Experts believe seismic activity in the metropolitan area has been intensified by changes in the movements of the Earth’s crust since March 11.

“Intensified seismic activity will continue from several to 10 more years,” Hirata said. “It’s highly probable a strong quake with a magnitude of about 7 will occur during that time.  (Jan. 24, 2012)

6th Strong Quake Strikes Near Ryukyu Isles, Japan

Posted by feww on September 29, 2009

6 to 8 more EQs may yet strike region

Magnitude 5.9 quake strikes near Ryukyu Islands, close to Iwo-Tori-Shima Volcano

Strong earthquake measuring 5.9 Mw struck near Ryukyu Islands, Japan region, at a depth of 10 km on September 28, 2009 at about 19:23 UTC, USGS EHP reported.

The quake struck about 200 km (125 miles) north of Naha, Okinawa, Japan. Japan Meteorological Agency reported an aftershock measuring 4.3 Mw at 07:48 local time (22:48 UTC). JMA issued NO tsunami warning after the mainshock.

This quake was in line with FEWW forecast made on August 17, 2009.

4th Powerful Quake Strikes Japan Region

Posted by feww on August 17, 2009

Magnitude 6.8 Quake Strikes Ryukyu Islands, Japan

FEWW Moderators had predicted more powerful earthquakes in the region last week, and now believe as many as 10 additional magnitude 6+ quakes could yet strike the region in coming weeks

Volcanic Activity Forecast

FEWW Moderators also believe there is a strong probability (0.8+) that the submarine Unnamed Volcano located East of Taiwan at 24.00N, 121.83E could erupt in 2009. [See previous comment.]
