At around 4:11 p.m., the U.S. Geological Survey reported a 3.2-magnitude quake struck the Fontana area. The quake had a depth of approximately 9 miles.
A USGS map showed the quake was centered between Fontana and Rancho Cucamonga, with shaking felt from La Verne in the west to San Bernardino in the east.
USGS also reported a 3.2-magnitude earthquake hit off the coast of Malibu around 2:38 p.m. In that quake, shaking was felt outside Thousand Oaks to the north, near Port Hueneme to the east and as far west as Canoga Park, according to a USGS map.
Saturday's quake near Malibu comes after a 4.7-magnitude earthquake struck the same area roughly two weeks ago. During that quake, the shaking was felt up to 60 miles away across Southern California.
There were no immediate reports of damage from either earthquake.
