Overview

Dzenzursky 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.

    Regional Volcanic Activity
    The Northwestern Pacific Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

    About the Photo

    Koryaksky is the tallest peak to the left in the background of this 1990 photo. The ridge to the right of Koryaksky is the eroded Pleistocene age Dzenzursky volcano. This view from the NE has the summit crater rim of Karymsky in the foreground.
