NASA Radar Images Show How Mexico Quake Deformed Earth<\/strong><\/p>\n

PASADENA, Calif. — NASA has released the first-ever airborne radar images of the deformation in Earth’s surface caused by a major earthquake — the magnitude 7.2 temblor that rocked Mexico’s state of Baja California and parts of the American Southwest on April 4.<\/p>\n

The data reveal that in the area studied, the quake moved the Calexico, Calif., region in a downward and southerly direction up to 80 centimeters (31 inches). The maps can be seen at: http:\/\/www.nasa.gov\/topics\/earth\/features\/UAVSARimage20100623.html .<\/p>\n

A science team at NASA’s Jet Propulsion Laboratory, Pasadena, Calif., used the JPL-developed Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) to measure surface deformation from the quake. The radar flies at an altitude of 12.5 kilometers (41,000 feet) on a Gulfstream-III aircraft from NASA’s Dryden Flight Research Center, Edwards, Calif.<\/p>\n

The team used a technique that detects minute changes in the distance between the aircraft and the ground over repeated, GPS-guided flights. The team combined data from flights on Oct. 21, 2009, and April 13, 2010. The resulting maps are called interferograms. <\/p><\/blockquote>\n
