A magnitude-5.1 earthquake struck the northern Baja California region of Mexico near the U.S. border Monday, just days after the region was hit with a magnitude-5.4 temblor, authorities said.

The quake was centered about 20 miles southeast of the border town of Mexicali at a depth of 4.3 miles, according to the U.S. Geological Survey. The epicenter was 23 miles south-southeast of the U.S. city of Calexico.

The latest temblor comes three days after the Mexicali area was rocked by a magnitude-5.4 quake that shut down factories and left 400,000 people without power.
