Between the initial 7.2 (beforeshock?) on 3-9 and the last 5.1 on 3-11 @ 20:41 utc Japan has had a total of 140 main and aftershocks of magnitude 4.6 or greater and 25 of those have ben at 6.0 or greater including the 7.2 and 8.9

Fifth strongest of the century? I've read that it may be even a 9 magnitude!

This is a real test of nuclear safety, here... Waiting to see to what degree of danger the nuclear material makes it to. Quite a catastrophe the plant has been through.

<<NASA’s Terra satellite’s first view of northeastern Japan in the wake of a devastating earthquake and tsunami reveal extensive flooding along the coast. The Moderate Resolution Imaging Spectroradiometer (MODIS) acquired the top image of the Sendai region on March 12, 2011, at 10:30 a.m. The lower image, taken by Terra MODIS on February 26, 2011, is provided as a point of reference.

Water is black or dark blue in these images. It is difficult to see the coastline in the March 12 image, but a thin green line outlines the shore. This green line is higher-elevation land that is above water, presumably preventing the flood of water from returning to the sea. The flood indicator on the lower image illustrates how far inland the flood extends.

Both images were made with infrared and visible light, a combination that increases the contrast between muddy water and land. Plant-covered land is green, while snow-covered land is pale blue. Clouds are white and pale blue. The paved surfaces in the city of Sendai colors it brown.

MODIS detected a fire burning near the shore north of Sendai. The fire is marked with a red box. It is also surrounded by floods.

The photo-like true-color image acquired a few hours later shows plumes of sediment washed into the ocean along the coast and a dark plume of smoke near Sendai. Both images are from the MODIS Rapid Response System, which provides twice-daily images of Japan.>>

Does anybody have any more educated guesses about the No. 1 reactor in Japan? I'm getting a bunch of what I am assuming is ridiculous hype about the thing around the internet. Example

I heard there was an explosion but it wasn't a nuclear explosion!

They detected elevated levels of atmospheric caesium which has been utilized to indicate a potential core meltdown situation in the past.
I believe the explosion at power reactor 1 was due to steam pressure and not a nuclear type explosion; however, the steam was radioactive and,
according to one report, was at a level 1000 times normal http://www.smdailyjournal.com/article_p ... nt&eddate=
Here is another that saye about the same thing

article wrote:Some 3,000 people within two miles (three kilometers) of the plant were urged to leave their homes, but the evacuation zone was more than tripled to 6.2 miles (10 kilometers) after authorities detected eight times the normal radiation levels outside the facility and 1,000 times normal inside Unit 1's control room.

Since the unit 1 explosion, the evacuation area was extended to 12 miles, 20 kilometers

I too have seen a statement about it being 1000 times normal in the control room, but I saw that before the explosion and I therefore think it is unrelated to the explosion.

That article is from yesterday. Here's one from CNN that was updated just a little while ago. It gives a more reassuring picture of the situation at the plants.

The initial data suggests Friday's earthquake moved Japan's main island about 8 feet, according to Kenneth Hudnut of the U.S. Geological Survey. The earthquake also shifted Earth's figure axis by about 6 1/2 inches (17 centimeters), Gross added.

Great news...with the extra added rotational speed creating a slightly greater offset to the effect of gravity, I should weigh less (diet's working better than I thought.)

now if I can just avoid that "num num num" thread

http://www.nydailynews.com/news/world/2 ... maged.html Radiation may be within legal limits; but it is still in need of containment.

Hopefully a degree of normalcy can be obtained as quickly as possible with the situation in Japan. I know it will take a long time to heal as do all disasters. I wish them well.

geckzilla · Post by **geckzilla** » Tue Mar 15, 2011 2:05 am

Nice articles, you guys. I knew that silly Youtube video was just plain wrong but probably should have made it more clear. While the containment and cleanup is ongoing it seems like the power plant still isn't posing a major threat to the environment even after withstanding more damage that it was ever designed to withstand.

One of the comments on bystander's link to a blog entry made a good point about the fires which continue to burn at a petrochemical plant (worth a whole 3 sentences) but no one seems alarmed at all about those. I've also read about an oil refinery fire which apparently is still burning.
