5.7 quake rattles nerves in border region

SAN DIEGO – The U.S.-Mexico border was rocked by a magnitude-5.7 earthquake Monday night, rattling nerves in a region still recovering from the deadly Easter jolt.

The U.S. Geological Survey said the quake was centered five miles southeast of Ocotillo in Imperial County — about 85 miles east of San Diego. It struck Monday at 9:26 p.m. PDT.

The quake was an aftershock of the deadly Easter Sunday magnitude-7.2 quake that shook Baja California and Southern California, said Egill Hauksson, a seismologist at the California Institute of Technology in Pasadena. He said the epicenter of Monday's quake occurred in the same zone of the quake in April.
