Earthquake! (Epicenter Two Miles North; Magnitude 5?)
An earthquake! 8:40 PM PST March 1, 2007. Epicenter apparently two miles due north, by Acalanes High School, at the corner of Pleasant Hill and Deer Hill Road. I always thought we were roughly halfway between the Hayward and the Calaveras faults, but clearly we are on something.
Within twelve minutes after the earthquake, 1343 people had sent their internet reports to the United States Geological Survey. 4851 responses within 20 minutes. That's a pretty good response, IMHO.
