The topography surrounding the Laguna Salada fault in the Mexican state of Baja, California, is clearly shown in this combined radar image and topographic view (right) generated with data from NASA's Shuttle Radar Topography Mission (SRTM). On April 4, 2010, a magnitude 7.2 earthquake struck along this fault about 64 kilometers (40 miles) south of the Mexico-United States border.
According to the U.S. Geological Survey, the earthquake was the largest to strike this area since 1892. This fault is a probable southern continuation of the Elsinore fault zone in Southern California, and is related to the San Andreas fault zone complex.
