3.5 earthquake near Idyllwild jostles parts of San Diego County

Parts of San Diego County were briefly jostled late Monday night by a 3.5 earthquake that occurred six miles north-northwest of Idyllwild in Riverside County, according to the US Geological Survey.

The quake hit at 11:39 p.m. and appears to have happened on or near the San Jacinto fault zone, a 130-mile system that partly cuts through San Diego County.

The USGS says that members of the public reported shaking in Oceanside, Carlsbad, Fallbrook, Bonsall, Pauma Valley, Pala, Poway, Valley Center, Escondido, Santee, Bonita, La Jolla and San Diego.

The temblor began 7.6 miles deep, a common depth for quakes in Southern California. Quakes of this size also are common in the region. A 3.9 quake occurred on the same fault, 15 miles north-northwest of Borrego Springs, on January 12.
