A modest earthquake struck a wide area of Southern California Monday, but there were no immediate reports of damage. The quake measured an estimated magnitude of 4.7, according to the California Institute of Technology's seismology laboratory in Pasadena. A number of aftershocks occurred as well, it said. The epicenter of the earthquake was roughly 19 kilometers from the Riverside County community of Anza, about 161 kilometers southeast of Los Angeles. The quake was felt sharply in the local area and caused a swaying or rolling motion in Los Angeles and San Diego as well as in Orange and San Bernardino counties. It was a strike-slip earthquake on the San Jacinto Fault, the most active fault in Southern California.
