Magnitude-4.6 Malibu earthquake shakes Southern California from coast to inland areas

Jonathan Lloyd

Shaking was reported across a widespread area that included the coast, downtown Los Angeles, the San Fernando Valley, South Bay, Riverside and Orange counties and elsewhere.

A magnitude-4.6 earthquake northwest of Malibu caused widespread shaking that was felt early Friday afternoon from the coast to inland areas of Southern California.

The quake was reported just before 2 p.m. about 7 miles northwest of Malibu in the Santa Monica Mountains. More than a dozen aftershocks, the largest of magnitudes 3.0 and 2.7, were reported within an hour in the same area.

"It's got a very robust aftershock sequence," said seismologist Dr. Lucy Jones, adding that the possibility that the quake was a foreshock to a larger seismic event rapidly diminishes over time.

Shaking was reported throughout the greater Los Angeles area, possibly by as many as 12 million people. The quake was felt from the LA, Orange and Ventura county coasts, including the South Bay and Long Beach, to inland areas like the San Fernando Valley, downtown LA, Riverside, Irvine and Anaheim.
