3.8 magnitude aftershock strikes Imperial Valley

INDIO - A magnitude 3.8 aftershock struck the Imperial Valley and may have been felt in the Coachella Valley, according to automated seismographs and computers operated by the U.S. Geological Survey.

The aftershock was centered 30 miles south of Mexicali, about 100 miles south-southeast of Indio. It hit at 11:37 a.m.

Thousands of similarly-sized aftershocks have rattled the area since a magnitude 7.2 earthquake struck April 2, killing two people in Mexicali and causing hundreds of millions dollars damage in Imperial County.
