UAVSAR interferogram of Southern California

UAVSAR interferogram of Southern California near the Mexican border, created by combining data from flights on April 13, 2010, and July 1, 2010. The interferogram shows the continued deformation in Earth's surface caused by the thousands of aftershocks from April 4th's magnitude 7.2 quake in Baja California. The different shades represent motions of the ground surface by a few inches upward or downward. Yellow shaded regions moved to the south or downward, regions in blue moved to the north or upward, and regions shaded in magenta showed no motion. Major fault lines are marked in red, and recent aftershocks are denoted by yellow, orange and red dots, with older earthquakes shown as gray dots.
