Zhupanovsky Volcano | John Seach
Kamchatka, Russia
53.590 N, 159.147 E
summit elevation 2958 m
Compound volcano
Zhupanovsky volcano is located in eastern Kamchatka, 65 km north of Petropavlovsk-Kamchatsky. Zhupanovsky is one of the least studied volcanoes in the region despite its proximity to a large city. The thickness of the crust beneath the volcano is 25-30 km.
Zhupanovsky is associated with a northwestern fault aligned with a chain of volcanoes of the Dzenzursky-Zhupanovsky ridge. Zhupanovsky consists of four stratovolcanoes of similar age and structure. The eastern cone is the highest (2958 m) and the western cone is the lowest (2505 m).
The summits of the cones contains craters with diameters ranging from 0.3 to 1.0 km. The crater fourth from the east is 0.35 x 0.55 km wide and 150 m deep. The crater third from the east is 300 m wide and 150 m deep.
Distinct lava flows are visible on the southern slope. Lava flows on the northern slope are buried under pyroclastics.
Eruptions at Zhupanovsky volcano
Eruptions consist of lava flows, ashfall and pyroclastic flows. Blocky lava flows are located on the northern slopes. All historic eruptions consisted of small explosions. There are two fumarole craters and one fumarole field on the western edge of cone 2. These release the greatest amount of heat at the volcano.
A future large eruption of Zhupanovsky volcano may pose a risk to Petropavlovsk-Kamchatsky.
2013-16 Eruption
Explosive eruption began at Zhupanovsky volcano on 1500 hr on 23 October 2013. Ash emissions reach 16,000 ft altitude and extended 75 km southeast of the volcano. The volcano was dormant for 56 years. Previous eruptions of Zhupanovsky volcano have been weak.
