BRAWLEY, Calif. — A series of small to moderate earthquakes that shattered windows and knocked trailer homes off their foundations is putting people in this small farming town east of San Diego on edge as they continue to feel jolts that scientists said could last for days.
The largest quake, registered at a magnitude 5.5, struck at 1:57 p.m. Sunday and was centered about three miles northwest of Brawley, said Robert Graves, a geophysicist with the U.S. Geological Survey. Another quake about an hour and a half earlier registered at magnitude 5.3.
No injuries were reported.
Several dozen earthquakes with magnitudes of at least 3.5 shook the same area near the southern end of the Salton Sea, Graves said.
By dawn Monday, the U.S. Geological Survey website showed there had been dozens of aftershocks in Imperial County, the largest a magniutude-4.9 at 9:41 p.m. Sunday. There was also a 3.0 at 12:32 a.m. Monday.
The first quake, with a magnitude of 3.9, occurred at 10:02 a.m. The USGS said more than 300 aftershocks struck the same approximate epicenter.
Some shaking was felt along the San Diego County coast in Del Mar, some 120 miles from the epicenter, as well as in southwestern Arizona and parts of northern Mexico.
