About Sedanka Lava Field
Sedanka Lava Field is a volcanic field rising to 1,399 meters (4,590 feet) in Russia's Northwestern Pacific Volcanic Regions. The volcano is currently active, with its most recent eruption in 7050 BCE. The volcano has produced 1 recorded eruption.
Geography & Climate
Sedanka Lava Field is located in Russia, within the Central Kamchatka Volcanic Arc of the broader Northwestern Pacific Volcanic Regions. Situated at 57.32° N, 160.07° E in the Northern Hemisphere, the volcano lies within a subarctic climate zone. With a summit elevation of 1,399 meters above sea level, Sedanka Lava Field is a moderately sized peak that remains accessible to hikers and researchers for much of the year. The volcanic landform is characterized as a cluster, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Sedanka Lava Field sits in a subduction zone, where one tectonic plate dives beneath another, creating intense heat and pressure that generates magma. Subduction zones are responsible for many of the world's most explosive volcanoes and deadliest eruptions. For communities in Russia near Sedanka Lava Field, this tectonic setting means the volcano is capable of producing powerful explosive eruptions, pyroclastic flows, and lahars that can threaten populated areas within tens of kilometers of the summit. The dominant rock type is basalt / picro-basalt, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
Eruption History Summary
Sedanka Lava Field has 1 recorded eruption in the geological database, spanning from 7050 BCE to 7050 BCE.
GVP Reference Summary
The Sedanka lava field (Sedanka Dol) is located immediately west of the Sredinny Range axis and is formed by dominantly mafic lavas from small strato- and shield-like volcanoes, along with more than 100 cinder and lava cones of the late Pleistocene-Holocene age. For this compilation the volcanic field area is considered to be up to 10 km wide and stretching about 25 km from south of Gorny Institute volcano towards the NNW between Tuzovsky volcano to the SW and Titila to the NE. Other workers (eg. Nekrylov et al., 2015) define the field to include the eight large edifices from Terpuk on the SW to Shishel on the NE.
