This is from the USGS Website. We live all of about oh, ONE MILE from the epicenter. Would have been exciting except for the fact that a) we weren't home, b) I've slept through MUCH larger earthquakes than this in California, and c) it was a teeny tiny earthquake (1.8 magnitude). So, here are the details - not quite as exciting as one might think.
