Three earthquakes shake parts of Riverside County, Malibu and across Westside and the San Fernando Valley. There are no reports of damage.

An earthquake with a preliminary magnitude of 3.5, the third above 3.0 in Southern California in the last several hours, struck the Inland Empire on Saturday afternoon.

A 3.5-magnitude earthquake struck near Malibu at 6:30 a.m. Saturday, following a 3.7 quake that hit the same area just before midnight, according to the U.S. Geological Survey.

The Malibu area was rattled by a second minor earthquake within a roughly seven-hour period Saturday as the area recovered from this week’s rainstorms and officials watched carefully for signs of possible debris flows.
