A moderate earthquake has rattled eastern San Diego County but there have been no reports of damage or injuries.
The U.S. Geological Survey says the magnitude 3.6 quake struck south of the border at 9:01 a.m. Saturday, about 25 miles south of the Mexican border town Mexicali.
The Imperial Valley region has been shaken frequently since a magnitude 7.2 earthquake struck just south of the border in Mexicali on Easter Sunday, with moderate aftershocks sometimes occurring four or five times a day.
