Epicenter of early morning quake was Salton seashore

East San Diego County and the Coachella and Imperial valleys rumbled with a series of earthquakes centered at the southern end of the Salton Sea early Saturday.

A magnitude 3.0 temblor started the latest sequence of shakes. It struck at 1:46 a.m., and its epicenter was on the Salton seashore 3 miles west-southwest of Niland, according to automated seismographs operated by the USGS and the Southern California Earthquake Center.

The 3.0 temblor was followed by a series of smaller microquakes.

There were no reports of damage in the area.
