A magnitude 4.6 earthquake struck the Imperial Valley and eastern San Diego County Thursday, and was widely felt across San Diego County.
The shock was centered about 20 miles north of Jacumba, or about 120 miles east of San Diego. It hit at 12:39 p.m.
The epicenter was in a mostly-unpopulated desert area 9 miles north of Ocotillo, on the San Diego-Imperial County line.
People responding to a USGS Internet page reported feeling weak shaking all across San Diego County. Moderate shaking was reported in East County locales like Campo and Dulzura.
It was also felt by people in the Rancho California and Temecula area of Riverside County, as well as the Coachella Valley.
Thousands of aftershocks have rattled the area since a magnitude 7.2 earthquake struck April 2, killing two people in Mexicali and severely damaging canals, schools and older buildings in Imperial County.
