An earthquake with an epicenter in the Santa Monica Mountains struck Los Angeles at about 6:25 a.m. today, authorities said. The U.S. Geological Survey listed the epicenter as 6 miles northwest of the city's Westwood neighborhood.
Initial reports by the USGS said the temblor was a magnitude 4.7, but that number quickly was downgraded to 4.4.
The jolt was felt in downtown Los Angeles and in Beverly Hills, and as far away as Palmdale and Camarillo.
"We've had a couple of aftershocks greater than magnitude 1.5," USGS seismologist Robert Graves told reporters about an hour after the quake was reported. "The most recent was at 7:23 (a.m.). We had a magnitude 2.7, which would cause very minor shaking, probably felt in the epicentral region.
"We're continuing to analyze the data, but at this point, this seems to be what I would call a rather typical earthquake of moderate magnitude," Graves said. "We don't expect there will be much damage."
Graves said the quake was a "reminder that we live in earthquake country" and emphasized the importance of residents devising an earthquake plan that includes emergency sources of food and water.
