A series of aftershocks in eastern San Diego County followed a 5.2 magnitude earthquake that rattled much of San Diego and Southern California Monday morning.

It all began with a 3.5 magnitude foreshock that hit just 3 miles south of Julian Sunday afternoon, USGS reported.

Then, at 10:08 a.m. Monday, a 5.2 magnitude earthquake hit around two miles south of Julian. Much of Southern California felt the quake.

Residents from Tijuana just across the U.S.-Mexico border all the way north to Los Angeles and all throughout San Diego County reported weak to strong shaking, the USGS shake map shows.

A series of at least eight aftershocks shook the region in the two hours immediately after, with some stronger than magnitude 3.0.

The aftershocks began at 10:10 a.m. with one measuring 2.9 magnitude, then another 2.9 at the same time.

At 10:11 a.m., a 2.7 magnitude aftershock hit, followed by a 2.6 at 10:12 a.m., all 3 to 5 km south of Julian, according to USGS.

Also at 10:12, the USGS registered a 3.5 magnitude aftershock 4 miles from Borrego Springs, east of Julian. 

At 10:13 a.m., a 3.0 magnitude aftershock hit 4 km south of Julian, and a 2.5 magnitude hit the same area at 10:14 a.m.

A 3.9 magnitude aftershock hit near Julian at 11:23 a.m.

Alert San Diego is alerting residents that aftershocks are possible and advises it is best to stay indoors and away from unstable structures. If shaking starts — drop, cover, and hold on.

There are no reports of any injuries or major damage from the earthquake or aftershocks at this time, the San Diego County Sheriff’s Office reports.
