Significant Aftershocks Follow Powerful Japan Quake

Posted by feww on October 26, 2013

Quake magnitude revised down to 7.1Mw, as significant aftershocks strike

Magnitude of the powerful earthquake that struck off Fukushima coast has been revised down to 7.1Mw by USGS/EHP.

The revised details are as follows

  • Magnitude: 7.1Mw
  • Time: 2013-10-26 02:10:16 UTC+09:00
  • Location: 37.170°N, 144.665°E [475km (295mi) ENE of Tokyo, Japan]
  • Depth: 10.0km

At least 4 significant aftershocks have occurred, as of posting, the largest of which measured 5.5Mw.

Meantime, the authorities evacuated the crippled Fukushima Power Plant, after Tsunami Advisories were issued.

The plant operator said on Saturday there was no damage or change in radiation levels at the station following the quake, according to reports.

A 30cm tsunami reached Japan’s east coast, NHK reported.

The quake reportedly shook buildings far away as Tokyo, about 230 km south of Fukushima nuclear plant, and 475km WSW of the epicenter.

Tsunami-hit Sendai Coast – Satellite Images

Tsunami impact on Sendai, Japan


Flooded fields on the tsunami-hit Sendai coast. Some of the fields are still waterlogged a week after the deadly tsunami spawned by the 9.0Mw Tohoku Megaquake caused much destruction along Japan’s eastern coast of Honshu. Photo-like image taken by ALI on NASA’s EO-1 satellite on March 18, 2011. Click image to enlarge. Download larger image (7 MB, JPEG)

Death Toll

Death toll in Japan’s twin disasters has reached about 7,400 with up to 11,000 others still missing.

Less Love for the Japanese Victims?

US charitable organizations have raised $64 million for Japan since the Tohoku Megaquake struck last Friday, a report said.

Six days after the Haiti earthquake struck, however, the same charities had raised $210 million. And in a similar period after Hurricane Katrina hit the US Gulf Coast they had raised $457 million.

Canadians also donated far less money to Japan than they did Haiti, a report said.

In the week following Haiti’s devastating quake last year, the Humanitarian Coalition (CARE Canada, Oxfam Canada, Oxfam-Québec and Save the Children Canada) raised $3.5 million. In the last 7 days, however, they have only raised $450,000 for Japan.

One reason might be that donors no longer trust charity organizations. They are wising up to the money black hole created by the international charity mafia. The sad fact is a great number of charities eat up as much as 95% of the contribution dollars. [See also comments about Haiti donations posted on this blog.]

The city of Rikuzentakata (population: 24,000) in Japan’s Iwate prefecture was almost entirely obliterated after the 9.0Mw megaquake and ensuing deadly tsunami struck. The above false-color images were taken by the ASTER instrument on NASA’s Terra satellite before and after the disaster. Source: NASA-EO.

The Human Toll

The official death toll in the Megaquake and the tsunami disasters, which is based on names registered with the authorities, stands at 5,695 perished with 9,503 people listed as missing, as of posting. Fire-Earth has previously stated that the actual death toll could reach into tens of thousands due to the severity of the twin catastrophes, a fear that has now been echoed by the Kyodo News Agency.

Homeless and Displaced

Up to 400,000 people are currently in temporary shelters, mostly school gymnasiums, enduring severe shortages of water food, warm clothing, heating fuel and all other basic essentials.

Aftershocks

The disaster zone is still bombarded with aftershocks, which are expected to continue for many weeks, possibly months. About 340 significant aftershocks (Magnitude ≥5.0) have swarmed the region since the Megaquake struck exactly a week ago.

Fukushima Nuclear Mess

An update will be posted later.

Threat of Nuclear Leak at Fukushima Nuclear Power Plant

Posted by feww on March 11, 2011

BREAKING NEWS:

Radioactive Leak Threatens Fukushima Nuclear Power Plant

The authorities have evacuated everyone living within a 3-km radius of the Fukushima Nuclear power plant because the battery used for one of the reactor’s emergency cooling system is running out, NHK has said.

Other residents living within the 3 to 10 km radius of the plant have been advised to stay indoors  and remain calm, while they await further instruction.

A nuclear leak is likely to occur, if the main cooling system fails to restart before the battery runs out.

Th e reactor was shut down after the magnitude 8.9 Mega Quake struck offshore east of the city Sendai, Japan earlier today.

Fukushima nuclear power plant, located in the town of Okuma in the Futaba District of Fukushima Prefecture, is one of the largest nuclear plants in the world, with 8 separate reactor units.

Sendai Mega Quake Update:

The estimated death toll in Japan’s Miyagi prefecture (state) from the mega quake and tsunami has reached at least 300. Authorities say about 300 people have drowned, NHK reported.

As of 05:40 JST (UTC+ 9 hours)
At some parts of the coasts, tsunamis may be higher than those observed at the observation sites.
The tsunamis can become higher from now on.

However, JMA later downgraded the warning to a tsunami advisory for the area.

Magnitude 6.2 Quake Strikes Kyushu, Japan

Posted by feww on September 3, 2009

Strong 6.2 Mw quake strikes off the south-western tip of the Island of Kyushu, Japan

The earthquake, reported by various seismic monitoring centers, occurred on Thursday, September 03, 2009 at 13:26 UTC at a depth of about 160 km some 70 km SW of Kagoshima, Kyushu, Japan.

The 6th strong quake to strike Japan Region in the past several weeks, this event was consistent with FEWW earlier forecast. On August 17, FEWW Moderators  forecast a series of  powerful earthquakes in the region and said as many as 10 additional magnitude 6+ quakes could yet strike the region in coming weeks.

Overall, the population in this region resides in structures that are a mix of vulnerable and earthquake resistant construction. A magnitude 6.9 earthquake and tsunami occurred in the Japan region 92 km northwest of the location of this earthquake on March 21, 1982 (UTC), with estimated population exposures of 48,000 at intensity VIII and 170,000 at intensity VII, with no reported fatalities. On July 12, 1993 (UTC), a magnitude 7.7 earthquake and tsunami occurred near the Hokkaido Nansei-Oki, Japan, region 360 km west of the location of this earthquake, with estimated population exposures of 4,000 at intensity VIII and 84,000 at intensity VII, resulting in an estimated 230 fatalities. Recent earthquakes in this area have caused, landslides and fires that may have contributed to losses. USGS.

NO tsunami warning has been issued.
