I live within about half an hour of Joplin, Missouri where they had that big tornado a few years ago. Slightly less recently, Missouri was affected by the most powerful known earthquake in US history, at the New Madrid fault. It was so powerful, it made parts of the Mississippi river flowed backwards. There weren't many deaths because there weren't many people living back then (it was sometime in the 1800s, like 1860 I think) and buildings weren't that tall, but now there's a lot of people and building so the next time something like that strikes it'll be pretty bad. And I hear that fault line is due, apparently it has big quakes about every 150 years. So yay for that.
