Earthquake rattles Southern California

Swarm of earthquakes hits seismically active region along California border

A swarm of small earthquakes hit a town near the U.S.-Mexico border Saturday and continued into Sunday(13 May).

Dozens of quakes were reported in and around Ocotillo Wells in Imperial County, six of them larger than a magnitude 3, according to the U.S. Geological Survey.

The largest were felt in a scattering of locations in Imperial, San Diego and Riverside counties, according to the USGS.

Seismologist Lucy Jones said on Twitter that the quakes were occurring along the southern end of the San Jacinto fault system. She said the location was not far from the site of the 1987 Superstition Hills quake, which measured 6.6 magnitude.

Earthquake swarms are nothing new to Imperial County, which is one of more seismically active parts of California. Most of the quakes are small, but there also have been destructive ones.
