The powerful earthquake that struck Baja California and the southwestern United States in April actually moved an entire California border city, NASA radar images show.

Calexico, Calif., near the U.S.-Mexico border, moved as much as 2 1/2 feet (80 cm) south and down into the ground due to the magnitude-7.2 earthquake on April 4.

Called the El Mayor-Cucapah earthquake, the temblor was centered 32 miles (52 km) south-southeast of Calexico and was the strongest quake to strike the region in nearly 120 years. Two people were killed and hundreds more were injured. [ LIVE SCIENCE ]
