EAST BAY -- A magnitude 3.6 earthquake struck Contra Costa County at 7:04 p.m. Saturday, according to the U.S. Geological Survey, an hour after a doomsday prophet predicted a catastrophic temblor would rock the Bay Area.
The earthquake was centered two miles south-southeast of Hercules, and eight miles north of Berkeley, the USGS reports. There have been no reports of any damage or injuries, a Contra Costa Fire District dispatcher said shortly after the quake.
