Minor earthquake. One of the stronger ones I've felt, though. I was reading the news, and I thought Ken had snuck up behind me and was shaking my chair. He was not. The shaking kept up for a good ten seconds after I realized it was an earthquake -- usually by the time I figure out what it is, it's over. Our Galileo thermometer rattled and some car alarms went off. The whole thing was a little freaky, but not scary.
