Multiple earthquakes struck Wednesday in the Pacific Ocean, just southwest of the Navy’s San Clemente Island, causing some shaking in parts of Los Angeles, Riverside and San Diego counties.

According to the U.S. Geological Survey, a magnitude-4.3 temblor struck at 3:47 a.m. at a depth of 5.2 miles, its epicenter about 38 miles south- southwest of Avalon on Catalina Island.

Reports on the USGS “Did You Feel It?” map showed light shaking could be felt along the coast from Santa Monica to San Clemente and as far inland as Hemet and Fontana.

Light shaking was also reported in San Diego County from Escondido to Chula Vista.

Another magnitude-4.3 quake struck the same area at 7:32 a.m. and also had a depth of 5.2 miles, according to the USGS. It was followed five minutes later by a 2.6-magnitude aftershock.

Reports showed light shaking was felt from Santa Monica to San Clemente during the second quake. Residents also felt light shaking in Hemet and La Jolla.

A fourth quake, measuring magnitude-2.9, hit the same area at 9:13 a.m. At 3:33 p.m., yet another quake occurred, measuring magnitude-3.3.

No damage or injuries were immediately reported.
