USGS: Quake Swarm Jostled Part of Southern California

A series of minor earthquakes rattled a rural area of Southern California near the U.S.-Mexico border this week, the U.S. Geological Survey reported.

No injuries or damage were reported after more than 35 temblors struck in the morning in what seismologists call a “swarm” of quakes.

The largest of the quakes on Monday recorded by the USGS was magnitude 4.3 at 7:31 a.m. and was centered 35 miles (58 kilometers) northwest of El Centro.

According to the Southern California Seismic Network, more than 35 small earthquakes were recorded Monday in the area over a short period.

The region of large farms in the desert near the Salton Sea is known for extensive seismicity.
