Bakening

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.
