170,000 evacuated for fears of radioactive contamination

Mon, 2011-03-14 09:41 — admin

As Japan's nuclear crisis continues to intensify authorities are racing against time to combat the threats of multiple reactor meltdowns. More than 170 thousand people have been evacuated from the country's quake-and- tsumani hit northeast, on Sunday, for fears of radioactive contamination.

Japanese power plant operators have been trying to keep temperatures down among a series of atomic reactors -- to prevent the current disaster from worsening.

Winds at Japan Power Plants Should Send Radiation out to Sea

Three reactor units at the Onagawa plant are being watched and controlled for radiation leaks and possible meltdown.

The wind direction may impact where the radiation goes both at a local level and even across the globe. The wind direction at both of these locations are similar since the Onagawa power plant is located just to the northeast of Fukushima power plant.

"The exact direction of the winds would have to be known at the time of the release of a large amount of radiation to understand exactly where the radiation would go," according to Expert Senior Global Meteorologist Jim Andrews.

It is unknown when a large release of radiation would occur, if at all, at this point.

"You can calculate how long the release of a radiation would take to cross the Pacific from Japan to the U.S. by choosing different speeds that the radioactive particles might be moving and using the direct distance between given locations- say Sendai, Japan, and Seattle, Wash.," Andrews added.

World sends disaster relief teams to Japan

GENEVA | Sat Mar 12, 2011 9:21am EST

The international community started to send disaster relief teams on Saturday to help Japan after it suffered a massive earthquake and tsunami, with the United Nations sending a group to help co-ordinate work.

"We are in the process of deploying 9 experts who are among the most experienced we have for dealing with catastrophes. They will help evaluate needs and coordinate assistance with Japanese authorities," Elisabeth Byrs, spokeswoman of the U.N. Office for the Coordination of Humanitarian Affairs (OCHA), told Reuters.

The 2011 off the Pacific coast of Tohoku Earthquake: Crustal Deformation and Fault Model

Mon, 2011-03-14 04:08 — admin

2011 off the pacific coast of Tohoku earthquake

 

A mega thrust earthquake with a moment magnitude 9.0 (JMA) occurred in Japan on March 11, 2011 (JST). The Geospacial Information Authority of Japan (GIS) constructed a fault model using coseismic surface displacement data observed by the GPS Earth Observation Network System (GEONET).

A preliminary fault model which consists of two rectangular faults with a uniform slip in an elastic half-space shows that

  • A total major rupture length reaches ~400 km with a fault width of ~80-90 km. (Northern segment: ~200 km long/ Sourthern segment: ~180 km long).
  • A fault upper edge is at a depth of 10 km.
  • A reverse fault motion is inferred. Slip amounts of northern segment and southern one are estimated to be ~28 m and ~6 m, respectively.
  • A total moment magnitude is 8.8. (Northern segment: Mw8.7 / Southern segment: Mw8.2)

    Nuclear Emergency at Fukushima Site Appears to be Coming Under Control

    Fukushima Nuclear Powerplant

    Given the events of the past few days, it may be prudent to consider that new concerns may arise.  However, it appears that the Fukushima nuclear powerplant are beginning to come under control.  Reactors are still shutdown and emergency procedures are starting to come under control.  However, cooling procedures appear to be taking effect.

    Full assessments of radiation releases need to take place.  Local radiation exposures near the Fukushima nuclear powerplant have been noted.  Those directly affected are undergoing medical evaluations.
