Imperial County was hit by more than a dozen small earthquakes Sunday, including a 5.4 quake near the Mexican border.


The first quake -- a magnitude 3.9 temblor -- occurred at 10:02 a.m. northwest of Brawley and was followed by a series of other quakes in the same general area, according to the U.S. Geological Survey. There were no immediate reports of serious damage or injuries, authorities said.


The quakes could be felt in the press box at the Del Mar Race Track in neighboring San Diego County, where the $1-million Pacific Classic is scheduled later Sunday.


Between 10 a.m. and 12:50 p.m., the same general area was shaken by quakes ranging in magnitude from 2.0 to 5.4, the USGS reported.


The burst of quakes took place roughly 16 miles from El Centro and 92 miles from Tijuana. In the last 10 days, there have been six earthquakes of magnitude 3.0 or greater centered nearby....
