Earthquake of magnitude 4.7 shakes Malibu in Southern California: USGS

LOS ANGELES (Reuters) -An earthquake of magnitude 4.7 shook the southern California city of Malibu and other parts of the Los Angeles region, the U.S. Geological Survey said on Thursday, but there were no initial reports of damage or injuries.

The quake struck 6 kilometers (3.7 miles) north of Malibu at 7:28 am PT and was at a shallow depth of about 11.3 kilometers (7.0 miles), the USGS said, and was followed by a series of tremors measuring between 2.7 and 3.4 magnitude. 

The Los Angeles Fire Department said it had completed its earthquake mode and found no significant infrastructure damage or injuries.

Residents in the Malibu area told local television they felt heavy shaking for 20 to 30 seconds, while people living down the coast and in downtown Los Angeles said they also felt shaking and rolling.
