The series of quakes began shortly before 11 a.m., with the magnitude-5.3 temblor occurring at 10:55 a.m. at a depth of 3 miles, the USGS said. The epicenter of that earthquake was located about 7 miles west of Calipatria and 25 miles north of El Centro, a city just north of the U.S.-Mexico border.
A magnitude-4.3 quake was also among the several dozen recorded in the area Saturday morning, the Geological Survey said.
There were no immediate reports of injuries or serious damage.
