Dozens of small to moderate earthquakes struck southeastern California on Sunday, knocking trailer homes off their foundations, shattering windows and rattling nerves in a small farming town east of San Diego.
The largest quake, at 1:57 p.m., registered at a magnitude 5.5 and was centered about three miles northwest of the town 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.
