Magnitude 4.4 earthquake shakes Southern California



A 4.4-magnitude earthquake shook Southern California about 25 miles east of downtown Los Angeles on Tuesday, but there were no immediate reports of damage or injuries, the U.S. Geological Survey said.

The quake struck about 7:33 p.m. local time, the USGS said. It was centered about three miles north of the city of La Verne in the San Gabriel Valley.

“It was like if somebody had grabbed it and was shaking the house,” Vickie Carillo of La Verne, who was watching “Jaws 2” with her son, told the Los Angeles Times.

USGS says a 3.4 quake followed a minute later.

The Associated Press reports that the main temblor was widely felt as either a sharp jolt near the epicenter or a rolling motion further away. It shook buildings for several seconds in downtown Los Angeles.

The earthquake was reported to be felt some 40 miles away in Sylmar to the northwest and 30 miles south in Huntington Beach.

CBS Los Angeles cites seismologist Lucy Jones who said Tuesday’s quake should not be expected to have done damage to structures.

Jones said the quake wasn’t on the Sierra Madre fault — one of the largest in the region — but on an ancillary structure.

Early reports say that quake was felt in Oceanside, Fallbrook, San Marcos, Del Mar, Escondido, San Diego, Poway and Ramona.

It appears that the quake occurred on or near the Sierra Madre fault system. Scientists say the fault is capable of producing a quake in the 6.0 to 7.0 range, and perhaps higher.
