3.2 quake hits California-Mexico border
The U.S. Geological Survey said the quake hit at about 9:07 p.m. The quake struck in an area of known for its high seismicity.
Almost a year ago, on April 4, 2010, the border region was hit by a magnitude-7.2 earthquake on Easter Sunday, which was felt all the way in downtown Los Angeles, and was so powerful it shifted the Earth’s crust up to 10 feet in Mexico. That quake was the largest to occur in Southern California since the 1990s, and about 45 buildings in Baja California collapsed or partially collapsed. Two people were killed in that quake, and at least 233 people were injured in the Mexicali area.
Scientists have said that the Easter Sunday earthquake could have increased seismic tension to the north, triggering the 5.4 earthquake on July 7 south of Palm Springs, which was also felt as far away as Los Angeles.
