4.1 Earthquake Shakes Southland

A magnitude-4.1 earthquake struck about 2 miles east-northeast of Yorba Linda, Calif., shortly after 1:30 p.m., according to the U.S. Geological Survey.

The temblor's epicenter was about 5.5 miles underground and about 29 miles east-southeast of downtown Los Angeles, according to the USGS.

Within the next 15 minutes, it was followed by two aftershocks of magnitude 2.1 and 1.5.

The Los Angeles Fire Department temporarily operated in emergency earthquake mode as fire crews at 106 neighborhood fire stations conducted area assessments to ensure there was no damage, according to spokesman Erik Scott.

No damage or injuries were reported. Quakes in the magnitude-4 range can cause moderate damage.

Within an hour of the shaking, more than 2,600 people in more than 300 ZIP codes reported feeling the earthquake on the USGS Community Internet Intensity Map. People reported feeling it as far north as Castaic and as far south as Spring Valley in San Diego County.

The earthquake appears to have occurred along the Whittier Fault. A —two of which were felt in the Los Angeles area—occurred in the same general area earlier this month.
