Bakening

Geography & Climate

Bakening is located in Russia, within the Eastern Kamchatka Volcanic Arc of the broader Northwestern Pacific Volcanic Regions. Situated at 53.91° N, 158.07° E in the Northern Hemisphere, the volcano lies within a temperate climate zone. At 2,278 meters above sea level, Bakening rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.

Geological Context

Bakening 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 Bakening, 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 andesite / basaltic andesite, 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

Bakening has 5 recorded eruptions in the geological database, spanning from 7550 BCE to 550 BCE. The most powerful recorded event was a severe eruption capable of regional ash fall and pyroclastic flows in 6550 BCE, reaching VEI 3 on the Volcanic Explosivity Index. This eruption frequency indicates a moderately active volcanic system with periodic reawakenings.

Significance

With a maximum recorded VEI of 3, Bakening has produced eruptions capable of generating pyroclastic flows and significant ash fall in the surrounding area. While not among the largest eruptions globally, VEI 3 events pose serious hazards to local populations and can disrupt regional air travel. With 5 recorded eruptions on file, Bakening has enough documented activity to help scientists identify patterns in its eruptive behavior.

GVP Reference Summary

Bakening (also known as Bakenin) lies well west of the eastern volcanic range of Kamchatka, at the head of the Srednyaya Avacha River, about 100 km NNW of Petropavlovsk. Most of the volcano is of Pleistocene age, and subglacial rhyodacitic tuyas are located on the NW flanks. The andesitic stratovolcano has dacitic lava domes at its N and NE base, the latest of which (Novo Bakening) formed about 9,000-10,000 years ago. A large scarp open to the SE was the source of a large debris avalanche about 8,000-8,500 years ago that traveled 11 km E and S. The avalanche, which dammed drainages forming two lakes NE and E of the volcano, was followed by an explosive eruption and a block-and-ash flow. Several late-Pleistocene to Holocene cinder cones are located on the northern-to-southern flanks. The latest dated activity consisted of the construction of a cinder cone at the western foot of the volcano about 2,500 years ago.
