This video shows the kind of destruction that ripped its way through Japan.
On a related note I hope global enthusiasm for nuclear power doesn't dissolve from this disaster. The Japanese are very competent people who have managed to control the situation very well. People are comparing this to a new Chernobyl, while this could be an apt comparison, it is not as technology has increased greatly since the time of that nuclear disaster.
At Chernobyl the Russians wanted to cut costs so they removed as many possible safety measures untill it all went BOOM! I dream of a future of much cleaner energy, and nuclear fission seems like one of the best ways to accomplish this goal.
