Southern California feels a 4.9-magnitude earthquake

Early on Monday afternoon, a magnitude 4.9 earthquake and other powerful aftershocks were detected throughout Southern California.

The epicenter of the earthquake, which occurred at 1 p.m. in San Bernardino County, was approximately 13 miles northeast of Barstow, according to the U.S. Geological Survey. A large portion of Southern California, including metropolitan Los Angeles and northern San Diego County, saw the effects.

The USGS swiftly reduced the earthquake's magnitude from 5.1 to 4.9 after first measuring it at 5.1. There were other large aftershocks measuring 3.5 and 2.7 in the aftermath.

The USGS recorded trembling as far east as Las Vegas, Nevada, and the majority of Southern California experienced the earthquake.

No immediate reports of injuries or damage were made.

Barstow is situated along the heavily trafficked Interstate 15 corridor, about 100 miles northeast of Los Angeles.

In California, thousands of earthquakes are reported annually, most of which are quite small. Just a few hundred are larger than magnitude 3.0, and just 15 to 20 are larger than magnitude 4.0, according to the USGS.
