Geologic Background:
Zhupanovsky is in the E Kamchatka district of
Cape Shipunsky, between the Nalycheva and Zhupanova
Rivers. The Zhupanovsky volcanic massif contains 4 summit
craters along a WNW-trending summit ridge. Zhupanovsky is
a basaltic-andesitic complex.
Historic Activity:
- Seven explosive eruptions from Zhupanovsky have been
documented since 1776, the most recent in 1959.
- The historical eruptions have consisted of moderate
Vulcanian explosions.
Recent Activity:
- Fumarolic activity was observed in February 1990 from
2 vents inside the active crater (3rd from the E) and 2
vents to the W.
- An overflight on Aug. 24, 1993 revealed that
significant fumarolic activity was present in the summit
area. Fumarolic emissions were coming from the active
crater, as well as from other parts of the summit ridge
west of the second cone's crater. Yellow sulfur deposits
were visible at several locations.
Data Sources:
- Global Volcanism Network (V. 15, No. 3 and V. 18, No.
8).
