Those poor folks. It just gets worse. here’s an update from the BBC that goes into detail about what might be happening at Fukushima Daiichi and how nuclear reactors work — and fail. Right now, the seriousness of the explosion is anybody’s guess.
And here’s an account of the Japanese history with natural disasters. The only good thing about this: If anybody is prepared for catastrophe, it’s the Japanese.
I know that some readers of this blog have friends over there. My best to them all — and please post in the comments if you have any word from the earthquake zone.

This seems to be the latest. It doesn’t look good.
