Salton Sea Fault: New fault discovered in earthquake-prone Southern California region

A swarm of nearly 200 small earthquakes that shook Southern California residents in the Salton Sea area last week raised concerns they might trigger a larger earthquake on the southern San Andreas Fault.

Nearly 200 earthquakes hit near SoCal's Salton Sea, USGS says. Scientists say earthquakes that occur near fault lines increase the chance that a larger quake will follow.

Almost 200 earthquakes were recorded in Southern California's Salton Sea in roughly a 24-hour period, geologists said Tuesday.
