New Event Horizon?

You should really have a look at this very comprehensive and informative entry on MutantFrog.com:

There is an awful lot of panic and speculation regarding the situation at the Fukushima #1 (Daiichi) Nuclear Power Plant and in particular its possible effects on the Tokyo Metro area. What is really going on?

Short answer – things seem to be pretty safe for now, but there is still a possibility of danger if things don’t go well.

A nuclear scientist on MetaFilter mentioned the following, based on what is currently known.

… while I would certainly be keeping a close eye on the situation if I were in Tokyo (!), I would not yet be very worried about health effects (or finding concrete bunkers) given the information currently available.

Tokyo Falling

Another explosion this morning spewed a large amount of radioactive material into the air. The actual vessel containing the core has been exposed. NYT The minister says “we are now talking about levels that are harmful to human health but we ask you to embrace this information calmly.”
Radiation around the reactor is now equal to three years ordinary exposure every hour. The winds have shifted and a thermal plume is expected to impact Tokyo by this evening. As of now (14:45 Tuesday), radiation levels in Tokyo are 22 times above normal. It is said that “this level will not immediately affect health.”
It is recommended that all people outside return indoors immediately unless absolutely necessary – and then use a mask. When returning brush off clothes and leave them outside. Do not drink tap water or have any food that has been outside (though food and water seem to be unavailable in my neighborhood shops). Close and tape all windows and turn off any heating or other ventilation system. Limit skin exposure after washing with soap and water.
Rain is expected shortly and any contact should be avoided due to radioactive contamination. The same is true for the snowfall forecast for tonight and tomorrow.

Quake Upgraded to 9.0

The Japan Meteorological Agency has revised the magnitude of Friday’s earthquake to 9.0, up from 8.9.

CNN quotes experts saying the earthquake appears to have moved the main island of Japan by 2.4m and shifted the Earth on its axis.

Reports from the National Institute of Geophysics and Volcanology in Italy estimated the quake shifted the planet on its axis by nearly 10cm.

Failure of cooling systems in reactor 1. At first radiation levels outside the plant were 8 times normal. They jumped to 90 times normal. Officials state that this is a dosage every hour equivalent to what one normally receives in a year. Not to worry, though, “a huge amount of radiation has not been released.”

Apparently even Tokyoites are being asked to remain indoors with windows closed and ventilation off for fears of a possible thermal plume coupled with a wind shift.

Three people had tested positive for elevated radiation levels yesterday. That number has now jumped to 160.

Now … “All the functions to keep cooling water levels in No. 3 reactor have failed,” plant operator Tokyo Electric Power (Tepco) said.

First it was 6,000 – then 45,000… Now about 140,000 people have been told to evacuate areas near the two Fukushima nuclear power plants. Revision by NHK … 392,225 people as of the very early morning not counting the greater than 10,000 missing.

Astounding images from Friday posted on boingboing.

The shop shelves have been restocked after being empty before. The government insists that it is safe. My worry is that with 35 million people in the greater Tokyo area … there is really nothing else they could say. The chaos and destruction from any other statement would pretty much …

Well, the death toll has now risen to 2,000. NHK reports Japanese self-defense forces assigned to relief missions have been doubled in number to 100,000. The aircraft carrier Ronald Reagan has arrived off the coast of Miyagi Prefecture to assist.

Through it all, Japanese manners remain unshakable … “She was elderly and alone, injured and in pain. When the massive earthquake struck, a heavy bookshelf toppled onto Hiroko Yamashita, pinning her down and shattering her ankle.
When paramedics finally reached her, agonizing hours later, Yamashita did what she said any “normal” person would do … She apologized to them for the inconvenience …”
