Just hours after millions of Californians participated in worldwide earthquakes drill, the real thing happened overnight.
A magnitude-3.7 earthquake centered in the Compton area just after midnight Friday morning, according to the U.S. Geological Survey. The temblor was reported at 12:19 a.m.
Light shaking was reported across a widespread part of Southern California, including well up the coast in Santa Barbara and Oxnard. Other communities that reported shaking include Santa Ana and Tustin in Orange County, Sunland and Panorama City in the San Fernando Valley, South Gate, Carson, Inglewood, Hermosa Beach, Manhattan Beach and other areas.
There were no reports of damage.
The earthquake, which was deep under the surface at 15 miles, appears to have been near, but not on the Newport-Inglewood fault, according to seismologist Dr. Lucy Jones. The fault runs near the communities of Culver City, Gardena, Compton, Signal Hill, Long Beach and coastal Orange County communities. It then extends offshore.
The shaking rattled the region hours after Thursday morning's Great Shakeout earthquake drill. The annual event is conducted to practice earthquake preparedness.
About 10 million people in California were expected to participate.
The quake also was a day after the 30th anniversary of the devastating Loma Prieta earthquake. The earthquake jolted the Bay Area, striking just befor the start of a World Series game between the A's and Giants at Candlestick Park.
