SAN DIEGO - An earthquake shook the Imperial Valley andeastern San Diego County Saturday afternoon, but was too small to cause any damage.
Automated seismographs indicated that the 3.9 magnitude quake, classified by the U.S. Geological Survey as a minor earthquake, hit at 3:02 p.m. with an epicenter 105 miles east of downtown San Diego, about 15 miles north-northeast of Ocotillo. That location is about 40 miles southeast of Borrego Springs, in an unpopulated area.
There were reports of people feeling the earthquake in El Cajon and Campo.
Caltech maps showed that the quake was midway between two recent clusters of epicenters from swarms of earthquakes near the crossroads town of Anza, and another seismically-active area south of Mexicali, B.C.
A waiter at a restaurant in Borrego Springs said today's quake was not felt by him or others, "but we have been drinking wine.''
