subsidence

NASA's UAVSAR measured cumulative vertical ground movement impacting the California Aqueduct near Huron and Kettleman City from July 2013 to March 2015. The colored overlay shows areas where subsidence exceeded 7 inches (17.8 centimeters). UAVSAR pixel resolution is 20 by 20 feet (6 by 6 meters). Credits: NASA/JPL-Caltech
