6.5 is actually a pretty strong earthquake.
I get eMail updates from the USGS and there have been amost daily 3.8 range quakes all over the state since Christmas.
California is one of the world's most seismically active regions. More than 300 faults crisscross the state, which sits atop two of Earth's major tectonic plates, the Pacific and North American plates. About 10,000 quakes each year rattle Southern California alone, although most of them are too small to be feltQuote:
