A small earthquake has jolted the Southern California coast but there are no reports of damages or injuries.

The U.S. Geological Survey says in a preliminary report that the magnitude-4.0 quake struck in the Channel Islands region at 10:14 p.m. Tuesday.

The USGS says the earthquake was centered 30 miles southwest of Malibu and was felt throughout the Los Angeles area, especially in West LA, Santa Monica and the San Fernando Valley.

Sheriff's and fire officials say there are no reports of damages or injuries from the quake, and the Los Angeles Fire Department is not in earthquake mode.

Brandon David Wilson, a school teacher who lives in the Culver City area, said on Twitter that he felt the earthquake, but it was "just a sharp jolt. No big whoop."
