Small Earthquake Rattles California Border

CALEXICO -A magnitude-3.9 earthquake has rattled the California-Mexico border, but there are no immediate reports of damage or injuries.

The U.S. Geological Survey said the quake occurred shortly after 7 a.m. Friday and was centered 16 miles southeast of Calexico, a California city of 40,000 people across the border from Mexicali, Mexico.

In December, a magnitude-5.8 temblor struck the area, forcing hospitals to evacuate in Mexicali. The quake did not cause any major property damage or injuries.
