Kizimen Volcano, Kamchatka

Kizimen volcano in Kamchatka, Russia is an isolated stratovolcano, with a summit elevation of 2400 m. The summit consists of overlapping lava domes. In the last few months, Kizimen has erupted sporadically, sending eruption plumes as high as 3 km, and drifting more than 170 km. On February 25, a large ash-laden eruption plume can be seen, drifting towards the northeast. Thermal data (red) shows the presence of recent hot block-and-ash flows from summit dome collapses. The data cover an area of 42 x 42km, and are located at 55.2 degrees north latitude, 160.5 degrees east longitude.

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.
