Quake strikes near Malibu, felt in in Los Angeles and Ventura counties

A 4.6-magnitude earthquake based in Malibu gave Southern California a serious shake Friday afternoon.

The temblor struck at 1:47 p.m. and was felt around Los Angeles and Ventura counties. The U.S. Geological Survey placed the quake's epicenter at 12 kilometers — about 7.5 miles — northwest of Malibu.

The shaking came days after a massive storm swept through an already disaster beleaguered region.

Multiple aftershocks had been recorded within an hour of the initial jolt, USGS data showed.

As of 2:40 p.m., county fire and sheriff's officials said they had received no calls for service regarding the quake.

Firefighter Andy VanSciver of the Ventura County Fire Department said no injuries or damage had been reported, but the agency activated its earthquake plan.

"We put our copter up" to do a survey from the air, VanSciver said. Engines were immediately moved outside so they'd be able to respond if secondary shaking damaged a station. Fire personnel were making "windshield surveys" of their districts to see if there was unreported damage to bridges, power poles and roadways, he said.

Fire officials advised residents to check their spaces and be sure they're away from anything that could be damaged.

Ventura County Sheriff's Capt. Greg Gibson also said there had been no calls for service and no reports of significant damage in the first hour after the quake was reported.

Initial reports from the National Weather Service's Tsunami Warning Center indicated that no threat of tsunami was expected.
