MONITORING OF ACTIVE VOLCANOES ON KAMCHATKA FROM THERMAL INFRARED SCANNER AND RADAR IMAGERY

On the basis of data recorded by a thermal infrared multispectral scanner (TIMS) carried on board an aircraft laboratory, maps of volcanic regions in Russia were compiled on which portions of lava dating to different periods were identified. SIR-C (Shuttle) data, processed by computer, made it possible to obtain distinct boundaries of lava flows with cross-polarization. A three-dimensional digital model of the Northern Fissure of the Great Tolbachik Fissure Eruption, on which TIMS, Zeiss, and SIR-C data were plotted, was constructed. A lineament analysis was made it possible to genetically classify cinder cones on the eastern slope of the Klyuchevskoy volcano, and a zone of areal volcanism was defined.
