A 5.0 magnitude earthquake shook San Diego County Saturday morning.
The U.S. Geological Survey says a magnitude 5.0 quake struck at 11:33 a.m. Saturday about 16 miles west-southwest of El Centro, near the small Imperial Valley farm town of Seeley.
A magnitude 4.7 quake hit about 15 minutes later in the same area.
San Diego County Sheriff's Lt. Hank Turner says some shaking was felt in downtown San Diego. Sheriff's and Fire Department dispatchers say no reports of damage were received.
