On July 17, 2016, one of the largest ice avalanches ever recorded tumbled down a Tibetan mountain, killing 9 people. The cause of the collapse is still unclear. On September 22, a second glacier, 1.9 miles (3 kilometers) farther south, collapsed. Geologists investigating the July collapse warned about the possibility of a second collapse, which did occur. The image covers an area of 7.8 by 10.2 miles (12.6 by 16.4 kilometers), was acquired October 4, 2017, and is located at 334 degrees north, 82.3 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.
