Matua Island is of volcanic origin and was formed by Sarychev Peak volcano. The island is a place of a specific anthropogenic landscape. Its structure was substantially changed by fortification constructions and other military objects. Analogues of such a landscape weren't described in scientific literature, thus, perhaps, it may be considered unique for Russia and it merits more detailed and indepth review. Results of ground penetration radar (GPR) survey of soil-pyroclastic cover of the island's southeastern part are presented, which include also an investigation of certain subsurface military objects, the greater part of which is unexplored. It's established that existence of objects, various soil disturbances, downwrappings, anthropogenic or natural faults can be located by some radiophysical indicators — details of the reflected pulse, disturbance of pulse lineups, numerous phase shifts and repeated rereflections. It is shown that elaborated methods and increased power GPR with 50—250 MHz antennas to be applied can effectively solve these tasks on complex multilayer and moist volcanic soils.
