CALEXICO — An earthquake rattled Baja California early Wednesday, but there were no immediate reports of injuries or damage. 

The magnitude-3.1 quake struck just before 6:02 p.m. about 19 miles southeast of Calexico, near the U.S.-Mexico border, according to a preliminary report from the U.S. Geological Survey. 

The quake apparently was related to a magnitude-5.7 quake that rattled Calexico on Feb. 22 but it was not immediately clear whether it was a direct aftershock, said Kate Hutton, a seismologist at the California Institute of Technology in Pasadena. 

A magnitude-4.7 quake was reported in Baja California on Wednesday, which followed a magnitude-4.4 quake on Tuesday. 

Also Tuesday, a magnitude-3.0 temblor hit an area about 12 miles north-northwest of Calexico.
