Dzenzursky Volcano — Russia

Dzenzursky is a strongly eroded stratovolcano of Pleistocene age that lies along a ridge extending NW from Zhupanovsky volcano. A series of Holocene cinder and lava cones along a ridge trending E and SE of the volcano produced extensive lava fields with flows that traveled primarily to the NE. Eruptions were reported in 1923 and 1957 CE (Vlodavetz and Piip 1959, Firstov et al. 1979); however, Fedotov and Masurenkov (1991) did not list any observed eruptions, and Ponomareva (1992, pers. comm.) stated that these reports were of hydrothermal or fumarolic activity.
