INDIO - A magnitude 4.1 aftershock struck the Imperial Valley today, and was likely felt in the Coachella Valley, according to automated seismographs and computers operated by the U.S. Geological Survey.

The aftershock was centered 11 miles west-southwest of Guadalupe Victoria, about 20 miles south of Mexicali and 100 miles south of Indio. It hit at 8:53 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 damaging schools, canals and older buildings in the Calexico area.
