A small earthquake rattled a desert town near the U.S.-Mexico border on Thursday, although there were no immediate reports of damage or injuries.

The magnitude-3.9 temblor struck at 7:08 p.m. and was centered eight miles southwest of Ocotillo, about 10 miles north of the border, according to a preliminary report from the U.S. Geological Survey.

There were no reports of injuries or damage, according to a dispatcher with the Imperial County Sheriff's Department.

Ocotillo is about 85 miles east of San Diego.
