A 4.4 magnitude earthquake struck Southern California around 7:33 p.m. local time Tuesday night, according to the U.S. Geological Survey (USGS). There were no immediate reports of injuries or damage.
The quake was centered about three miles north of La Verne, California, in the San Gabriel Valley. The epicenter was located about 25 miles east of downtown Los Angeles.
USGS said a 3.4 quake followed a minute later.
The Associated Press reported 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 felt some 40 miles away in Sylmar to the northwest and 30 miles south in Huntington Beach, AP said.
CBS Los Angeles cited seismologist Lucy Jones who said Tuesday's quake should not be expected to have done damage to structures.
Jones explained the quake wasn't on the Sierra Madre fault -- one of the largest in the region -- but on an ancillary structure.
