The Ksudach volcano is one of the most complicated and dynamic volcanic centre of the Russian Far East located on the south of Kamchatka peninsula. Modern cone of the volcano is composite construction with five different size and time calderas, two lakes and recent Shtubel’s cone. Studying of modern terrain dynamics on the volcano can be carried out with by comparison of two digital elevation (hypso- and bathy-) models for state of 80s in the 20 century (created on the data of aerial photographs and the bathymetric surveys) and for modern state (on the data of ArcticDEM and digital echosounding bathymetric survey with synchronized satellite fixation of the profiles). The elevation models like these (for Kamchatka’s volcanes and for different it’s conditions) were created at the first time. Its comparison allowed us to recognize new underwater extrusion dome with extensive underwater gas-hydrothermal outlets. Besides this we got the possibilities for clear bordering of different-time calderas using fractures on the automatic traceabled small river profiles. Comparison of high-resolution different-time DEMs for volcanic research is relatively new and perspective way for understanding volcanic life and development.
