A small earthquake rattled a rugged mountain area in southeastern California, but there were no immediate reports of injuries or damage.

The magnitude-4.3 quake struck about 5:28 p.m. Thursday and was centered about 6 miles southwest of the Salton Sea, according to a preliminary report by the U.S. Geological Survey.

A magnitude-3.2 aftershock struck about two minutes later.

The 376-square-mile Salton Sea, about 75 miles northeast of San Diego, is California's largest lake.
