5.1 quake strikes near Ocotillo

A 5.1-magnitude earthquake centered at the U.S.-Mexico border near El Centro rattled San Diego County on Tuesday evening, noticeably shaking the ground as far north as Escondido but causing no reported injuries or damage.

The temblor struck about 11 miles east-southeast of Ocotillo at 5:39 p.m., according to the U.S. Geological Survey.

People in buildings in downtown San Diego reported feeling a single sharp jolt that set some light fixtures swinging.

Due to the location of the epicenter, the shaker was almost certainly an aftershock from the Easter Sunday quake that devastated communities in northern Baja California, San Diego State University geology professor Pat Abbott told 10News.
