The Earth Moved

There have been some whopper earthquakes lately, and naturally that appalls all of us, but no one more, most likely, than the vulnerable citizens of California, who know that one of these days, that shaking is likely to be coming to their own stomping grounds, even though like all other residents of this state, I try not to think about it. I heard today that the Chile earthquake, the second largest one ever, actually shortened earth's day slightly. That's pretty awe inspiring, isn't it?
