Multiple Aftershocks Rattle San Diego Area Following Strong Earthquake

SAN DIEGO, CA — A series of aftershocks continue to rattle the San Diego region following a powerful earthquake that stuck Monday morning near Julian.

A 5.2 magnitude quake was recorded at 10:08 a.m. about 2.5 miles south of the mountain town of Julian in San Diego County, according to the U.S. Geological Survey. The quake had a depth of about 8.3 miles.

The shaking was felt in Orange and Riverside counties and as far away as Los Angeles.

At least six smaller aftershocks with magnitude readings of less than 3.0 happened within the 10 minutes following the quake, according to the USGS. Another 3.5 magnitude quake struck near Borrego Springs, roughly 30 miles east of Julian.

A 3.9 magnitude quake was recorded at 11:23 a.m. about 2.5 miles south-southeast of Julian, according to the USGS. That quake had a depth of about 7.7 miles.

Residents reported feeling the aftershock across the county, including in Carlsbad, El Cajon, Escondido, La Mesa, Poway, San Diego, Santee and Vista. The quake was felt in the Inland Empire and Orange County, according to the USGS's "Did You Feel It?" map.

The San Diego County Sheriff's Office said it had not received any reports of injuries or major damage caused by the earthquake.

Caltrans, however, warned drivers to watch out for obstacles in the roadway after boulders fell onto state Route 76, east of East Grade Road near the Lake Henshaw area.

"Caltrans crews are out assessing the highway infrastructure for any damage from this morning's earthquake," the agency said on social media.
