San Diego free from damage after Imperial Valley quake ‘swarm’

No damage was reported in San Diego County after a “seismic swarm” of earthquakes rocked neighboring Imperial Valley this weekend.
More than 360 minor earthquakes were reported in and around the Imperial County city of Brawley between the Salton Sea and the Mexican Border beginning at around 4 a.m. Saturday and continuing until late afternoon Sunday, according to the U.S. Geological Survey.
The strongest one, registering at magnitude-4.7 shortly after midnight, was still considered a light quake. The others ranged between micro, minor and slight, according to the USGS.
Geology Professor Emeritus Pat Abbott of San Diego State University told City News Service that a swarm like this is not unusual.
“These earthquake swarms happen here every few years,” Abbott said. “The swarm will not spread. No damages or injuries are expected to occur.”
Abbott also said he expects the swam to continue for the next few days, “but historically they do not lead to a big earthquake.” The swarm is not occurring on fault lines per se, according to Abbott, but rather represents “hundreds of little movements within the Brawley Seismic Zone.”
Lt. Joe Barry, the San Diego County Sheriff’s Office watch commander on duty Sunday, told City News Service that there have been no calls to his office regarding the earthquakes.
