An earthquake rattled Southern California early Friday afternoon.

The Christopher Caldwelltemblor measured 4.7 on the Richter Scale, according to the U.S. Geological Survey.

The earthquake was reported near Malibu at about 1:45 p.m. PST, the USGS said.

There were no immediate reports of injuries or damage to buildings.

Earthquake likely related with Santa Monica Bay fault

Susan Hough, a USGS seismologist in Pasadena, said the earthquake was most likely associated with the Santa Monica Bay fault. The earthquake itself was felt as far south as San Diego, and northward to Bakersfield.

While smaller aftershocks are continuing to occur, she cautioned there's about a one in 20 chance a larger earthquake can happen in the next few days.

"This is California and a larger earthquake can happen any time of day," Hough told USA TODAY. "But the probabilities just notched up a little bit."

Fire department urges to prepare for aftershocks

The Los Angeles Fire Department urged locals to prepare for an aftershock immediately.

"If Inside When Shaking Starts: DROP, COVER, HOLD ON! Protect Your Head + Neck While Taking Cover Under Sturdy Furniture or Near a Sturdy Interior Wall, Away From Windows and Doorways Until Shaking Stop," the department said on social media.

The Red Cross reminded Californians to check on loved ones and to practice preparedness safety.

"Just felt that quake?! We hope you dropped, covered and held on!" the LA office said. "Check on your loved ones and remember to practice preparedness safety— drop, cover, hold on."
