BackgroundDzenzursky is a strongly eroded stratovolcano of Pleistocene age that lies along a ridge extending NW from Zhupanovsky volcano. After a long quiescence, eruptions resumed during the Holocene. A series of cinder and lava cones along a ridge trending east and SE of the volcano produced extensive fresh-looking lava fields with flows that traveled primarily to the NE. Two historical eruptions have been reported (Vlodavetz and Piip 1959, Firstov et al. 1979), however Fedotov and Masurenkov (1991) did not list historical eruptions, and Ponomareva (1992, pers. comm.) stated that these reports actually consisted of hydrothermal or fumarolic activity.
