M6.5 Aftershock Strikes Offshore Miyagi

Posted by feww on March 28, 2011

Strong aftershock strikes 109 km  E of Sendai, Japan

Tsunami Warning

Japan’s Meteorological Agency (JMA) initially warned that a 50-cm tsunami could hit Miyagi coast, but later removed the tsunami advisory.

Earthquake Details

Magnitude: 6.5
Occurred at (JST):  07:24 JST Mar 28, 2011
Location:  38.3ºN, 142.4ºE

NO links between large quakes?

Two researchers from USGS and University of Texas who have analyzed  recent earthquakes greater than magnitude 7, say they have found “no link” between them.

[Presumably some of them are caused by the movement of moon, while the others are caused by Venus, or Mars!!]

The study is being published by the journal Nature Geoscience, a report said.

Meltdown Confirmed at Fukushima Nuke Power Reactors

Posted by feww on March 12, 2011

NUKE PLANTS IN QUAKE ZONES: EXPLOSIVE MIX!

BREAKING NEWS

Massive Explosion at Fukushima Dai-ichi Nuclear Power Plant, Core Meltdown Occurring: Scientists

The explosion tore down the walls of a unit within the Fukushima power plant Saturday as a large plume of smoke poured out.  Several workers were reported injured, and Japanese officials said a reactor core meltdown was likely to occur.

Independent scientists have since confirmed that, based on the available evidence, reactor core meltdown must be occurring.

The pressure in the reactor had built up to more than twice the normal level, after the shutdown of cooling systems caused by the Sendai Mega Quake and its ensuing Tsunami. The Plant is now venting “radioactive vapors,”  Japan’s Nuclear and Industrial Safety Agency said in a statement. Radioactive iodine and caesium has been detected outside the No. 1 one reactor of the Fukushima Dai-Ichi No. 1 plant, the agency said, adding that the uranium fuel rods inside the reactor may have begun melting.

Radioactive steam has been allowed to escape from a number of the reactors at the two Fukushima plants  in order to relieve the huge pressure that has built up inside the cores.

Tens of thousands of people living within the 20-km radius of the No. 1 plant and 10-km radius of No.2 plant  have now been evacuated.

Meanwhile, Japan’s Prime Minister has declared a state of emergency at the two Fukushima nuclear power plants.

As many as 300 people have received varying degrees of radiation, including 60 students at high school in Fukushima located about 3.5km from Plant No. 1, who were waiting to be evacuated.

The reactor core meltdown is feared to be “much worse” than the Three-Mile Island incident.

Radiation Leak at Fukushima Nuclear Power Plant

Posted by feww on March 12, 2011

BREAKING NEWS

Radiation Leak Confirmed at Fukushima Nuclear Power Plant Reactor No. 1 Following Sendai Mega Quake

Fukushima Reactor No. 2 Threatens to Leak

Nuclear reactor No. 1

Japanese authorities have confirmed radiation leak at Fukushima Nuclear Power Plant Reactor No. 1, and have evacuated people living with a 10-km radius of the reactor.

Nuclear reactor No. 2

They now fear radiation leak at the Plant’s Reactor No. 2, and have evacuated people living within a 3-km radius  of that reactor. They have also put on evacuation notice everyone living within a 10-km radius of the reactor

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.

JAPAN MEGA QUAKE UPDATE #2

Posted by feww on March 11, 2011

M8.9 Mega Quake Strikes Offshore 130km East of Sendai City, Japan

The Sendai Megaquake with 1.41 exajoule of energy (about 340 megaton, or 24,000 times the size of Hiroshima A-bomb) has caused much destruction in Japan

[NOTE: Humans are currently consuming the equivalent of energy released by Sendai Mega Quake each day. ]

Summary of Events:

  • Large earthquake measuring 8.9Mw struck near the east coast of HONSHU, JAPAN on Friday, March 11, 2011 at 05:46:23 UTC
  • The epicenter was located at 38.322°N, 142.369°E, about 130 km (80 miles) E of Sendai, Honshu, Japan.
  • At least 37 significant aftershocks have struck the area, including 2 measuring 7.1 and 6.8 respectively, as of 11:16UTC on Friday March 11, 2011.
  • Another 12 aftershocks measure ≥6.0.
  • The aftershocks will continue to strike the area for many weeks, possibly months, to come.
  • The quake was the largest ever to hit Japan region.
  • The Mega quake will prove to be an “earth-shattering” event.
  • FIRE-EARTH believes at least one more shock, probably larger than this event, could strike Japan Region. [See also earlier earthquake forecasts for Japan Region in the blog.]
  • A previous FIRE-EARTH forecast for earthquakes in Japan region is posted at Tectonics Update – March 10.

THE SENDAI TSUNAMI

  • The Mega Quake generated a massive tsunami which struck the coastal areas of Japan and is now traveling throughout the Pacific Ocean.

As of posting:

  • A tsunami warning has been issued for the entire Pacific basin (mainland United States and Canada not included),  the Pacific Tsunami Warning Center said.
  • “The Tsunami Warning continues in effect for the coastal areas of California and Oregon from Point Concepcion, California to the Oregon-Washington border.” WCA Tsunami Warning Center said.
  • “The Tsunami Warning continues in effect for the coastal areas of Alaska from Amchitka Pass, Alaska (125 miles W of Adak) to Attu, Alaska.” WCA Tsunami Warning Center said.
  • The list of countries include: Taiwan, Russia, the Philippines,  Papua New Guinea, Indonesia, Fiji, Mexico, Guatemala, El Salvador, Nicaragua, Honduras, Costa Rica,  Panama, Chile, Colombia, Ecuador and Peru.
  • The tsunami could destroy entire low-lying islands in the Pacific region.
  • The Russian authorities have evacuated 11,000 people from coastal areas of Russia’s Kuril Islands, a report said.
  • “Waves up to three meters high triggered by the earthquake hit Shikotan, one of the Kuril Islands, following the quake. Other islands in the Kuril chain have also been hit by smaller waves of up to two meters.”

  • At least 20 countries are under tsunami warning.
  • A 10-m wall of water struck the east coast of Honshu and traveled across the land, destroying everything in its path.
  • The quake and thee tsunami have claimed an unknown number of lives in Japan, possibly very many. Many others have been injured. [Early reports put the number of dead at 69 and the injured at several hundred, but the toll should be expected to rise. Many are reported as missing.]
  • The cost of damage from the quakes and tsunami could conceivably reach a trillion dollars.
  • An oil refinery in Shiogama city, Fukushima prefecture exploded.
  • Large fires were reported at a major refinery in Japan’s Chiba prefecture.

Fukushima Nuclear Power Plant

  • The authorities have declared emergencies at two of Japan’s nuclear power plants over cooling-system fears.
  • The nuclear power plant in Fukushima developed a mechanical failure in its emergency cooling system after the reactor was shut down following the earthquake, Chief Cabinet Secretary Yukio Edano was reported as saying.
  • At the Tohoku Electric Power Co’s Onagawa facility the cooling mechanism for the reactor is “not going as planned,” causing a “nuclear emergency situation” to be declared, the Administrator said. The company has asked people living nearby to stay indoors and remain calm, local TV station was reported as saying.
