Double earthquakes on San Andreas Fault rock California-Mexico border

April 2015 – CALIFORNIA – The U.S. Geological Survey says two magnitude 4.0-plus earthquakes have struck the San Andreas Fault on the California-Mexico border. The first one, a magnitude 4.2, struck at 12:30 p.m. PDT 7 miles southwest of Delta, B.C., Mexico at a depth of 16.1 miles. The second quake, measuring in at a magnitude of 4.5, struck the same area about three minutes later, but only at a depth of .44 miles. Quakes just below the earth’s surface, in the 0 to 10 miles range, can cause even more damage at lower magnitudes. Several people reported feeling the quakes in Mexicali, Mexico and Calexico in California. There were no immediate reports of damage. –CBS
