Whee!
A 5.2-magnitude earthquake hit just south of Gilroy (between 25 and 50 miles south of here), about half an hour ago. I felt it as just a slight swaying; by the time I realized it was a quake, it was over. My upstairs neighbors suddenly started moving around. I went to stand in a doorway briefly in case of aftershocks, but fairly shortly came back to the computer to see if it had really been a quake, and if so how strong and where. Sure enough, the USGS Recent Earthquakes in California and Nevada page was showing a quake of unknown intensity; reloading a couple minutes later gave the actual magnitude. They've got a page on which you can report your experience of a given quake, to help them map how and where people felt it. Pretty cool.
Kind of interesting, too, because yesterday at The Tech Kam was showing us some interesting earthquake-modeling software that shows how the quake waves propagate through the Earth—took less than ten minutes for the shock of various big quakes to go through the whole planet. We also stood on the quake-simulator platform, which gave us a bit more shaking than I felt in today's real quake.
