It appears to be on the San Jacinto Fault and at 5.6 would not be expected to affect the San Andreas. But, then again . . .
Ok, finally, from the Foxnews website:
PALM SPRINGS, Calif. — A mild earthquake shook the desert early Sunday and could be felt in Los Angeles (search) and San Diego. There were no immediate reports of any injuries or damage, authorities said.
The magnitude-5.6 quake struck about 8:40 a.m. and was centered 20 miles south of Palm Springs (search), according to a preliminary report by the U.S. Geological Survey.
A dispatcher with the Riverside County Sheriff's Department (search) said she received dozens of calls about the quake but hadn't received any word about injuries or damage.
The quake was felt as far west as Los Angeles, where it rolled for several seconds, and as far south as San Diego, 75 miles southwest of Palm Springs.
No other details were immediately available.
