BORREGO SPRINGS, Calif. (KABC) -- An earthquake with a preliminary magnitude of 5.2 shook Southern California early Friday morning.

There were no immediate reports of injuries or damage, San Diego Sheriff's Lt. Andrea Arreola said.

"At this point, we are just monitoring the area," she said.

Hemet police said the earthquake set off a lot of alarms at businesses.

The earthquake occurred along the San Jacinto Fault, historically the most active fault in Southern California, according to seismologist Lucy Jones. She added the quake was near the location of a magnitude-6.0 quake in 1937 and a 5.3-magnitude one in 1980.

Within an hour, there were six aftershocks in the same general area, the strongest a magnitude-3.5 shaker at 1:06 a.m. with roughly the same epicenter but at a depth of 6.7 miles.

A 3.5- and 3.8-magnitude aftershock struck several hours later, each a little more than 10 miles north, northwest of Borrego Springs, according to USGS.
