5.3-magnitude quake hits off coast of Southern California

The quake, which struck about 86 miles from Los Angeles around 12:30 p.m., registered a magnitude of 5.3, according to the U.S. Geological Survey.

"We would expect aftershocks, and there is the potential for some triggered seismicity", Andrews said.

"We have not had any reports of casualties or damage", police officer Hasmin Mondilla told AFP by telephone. It struck about 10.5 miles underground, the USGS said.

Some people in the Los Angeles area received about a 10-second warning before the shaking hit thanks to the state's quake early warning system, according to seismologists at the California Institute of Technology.

"Earthquakes are not at all predictable".

An early warning system did alert residents in Los Angeles before the shaking was felt, Caltech confirms.

The temblor was centered just off the Ventura County coast.

The Los Angeles Fire Department went into "earthquake mode" following the quake, meaning units will conduct surveys of their areas of the city to check things such as power lines, dams and transportation infrastructure. The quake was felt across much of Southern California as well, according to news reports.

Some bricks fell from a chimney at an 1860s ranch on Santa Cruz Island but no one was hurt, Yvonne Menard said, spokeswoman for Channel Islands National Park.

Fire officials in Ventura County, close to the epicenter of the quake, also reported no damage from the shaker.
