Update 8:20 p.m. Another quake, this one a 3.8, epicenter right on the UC Berkeley campus. Check out the map from the USGS and zoom in all the way to see the location. It appears to be a house right off of Piedmont Avenue. (Update 9:06 p.m. Berkeleyside says it's the International House.)
Here are all of the responses coming in on the USGS "Did you feel it" page.
No tsunami alert, by the way.
