San Diego • Dozens of small to moderate earthquakes rattled Southern California on Sunday, shaking an area from rural Imperial County to the San Diego coast and north into the Coachella Valley.
The largest quake, magnitude 5.3, struck at 12:31 p.m. about three miles north-northwest of the small Imperial County farming town of Brawley, according to Paul Caruso, a geophysicist with the U.S. Geological Survey. It was followed minutes later by a magnitude-4.9 quake.
The first quake had a magnitude of 3.9 and hit at 10:02 a.m. It was followed by a smaller quake about 90 seconds later in the same area near the southern end of the Salton Sea, and other smaller quakes followed within six minutes of the first shock.
