Volcanic eruption forecast and timely warning is the only possibility to reduce the risks and minimize the consequences of volcanic impact on the environment and civilization. The system of the space monitoring of catastrophic phenomena serves the purposes of the detection and recognition of eruption precursors, ongoing event monitoring and eruption dynamics scenario development with the objective to estimate eruption scale and environmental impact. Threedimensional digital elevation models (DEMs) of active volcanoes of Kamchatka and the Kuril Islands were compiled with subsequent development of their catastrophic eruption scenarios. The main instruments applied for the studies of the Earths natural resources, successful volcano monitoring in particular, are the Moderate Resolution Imaging Spectroradiometer (MODIS) and Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER). Computer processing of SAR interferometry data acquired by the Shuttle Radar Topography Mission (SRTM) and the possibility to compile new three-dimensional digital data layers enables the prompt assessment of erupted material extent and volumes during future eruptions in real-time mode.
