Scientific paper

Recently-released topographic data from the Shuttle Radar Topography Mission (SRTM) are being used as part of a joint collaboration between the U.S. Geological Survey, Univ. Alaska, and Univ. Hawaii to investigate the diversity of volcanic activity within the Kurile Islands and Kamchatkan Peninsula. SRTM data have a spatial resolution of 90 m, a vertical accuracy of ˜10 meters, and provide unique information on the height, slope and aspect of the ˜50 historically active volcanoes in the region. SRTM data also provide the context information for the position of hotspots on the volcanoes, serving as an aid to the geolocation of thermal anomalies on active volcanoes (e.g., Sheveluch, Bezymianny and Karymsky) using the MODIS instruments on NASA's Terra and Aqua spacecraft. Using the MODVOLC algorithm, we use MODIS observations to provide the team with thermal alerts for the volcanoes in a time frame that is typically less than 24 hours after at-sensor measurement of the emitted radiance. Under the Hawaii Synergy Project, we are also building a database of Landsat 7 data that can be merged with the SRTM elevation data to aid in visualization of the region. The application of SRTM data to the monitoring of the volcanoes will be discussed.
