Site of Destructive China Temblor Imaged by NASA Spacecraft

On Aug. 3, 2014, a magnitude 6.1 earthquake struck in southern China's Yunnan province, toppling thousands of homes and causing numerous casualties. Hardest hit was Zhaotang City, located 18 miles (29 kilometers) east of the epicenter. This temblor was more damaging than a similar one two years earlier in the same region. The region where the quake occurred is shown in this perspective view from the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument on NASA's Terra spacecraft. It depicts vegetation in shades of red. The image looks toward the northwest and was acquired March 16, 2009. The star indicates the quake's epicenter location at 27.2 degrees north, 104.4 degrees east.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
