Bolshoi-Kekuknaysky

Tipo
Vulcano a scudo
Altitudine
1401 m
Ultima eruzione
-5310
Kekuk crater on the lower northern flank of the Bolshoi-Kekuknaysky volcanic complex formed about 7,200 years ago. The 1-km-wide crater formed beside a lava dome (left) which likely was erupted immediately prior to formation of the crater. Bolshoi and Kekuknaysky are two large partially overlapping Pleistocene edifices that contain scoria cones on their flanks.

Sintesi geologica

Bolshoi (Bolshoy) and Kekuknaysky are two large, partially overlapping basaltic shield volcanoes located NW and NNW, respectively, of Uksichan volcano. The massive Pleistocene shield volcanoes were constructed west of the axis of the Sredinny Range. Hawaiian-type calderas are located at the summits, and their flanks have numerous youthful cinder cones. The summit caldera of Bolshoi is breached by four radial valleys, whereas the 6-km-wide caldera of Kekuknaysky (also known as Leningradets volcano) is breached to the north. Young cinder cones and lava flows are particularly abundant on the NE flank of Kekuknaysky. Kekuk crater on the lower N flank erupted about 7,200 years ago.

Riassunto in inglese

Bolshoy Kekuknaysky is a volcano located in the central part of the Kamchatka Peninsula, Russia. It comprises two shield volcanoes: Bolshoy (1301 m) and Kekuknaysky (1401 m). Their lava flows and cinder cones have dammed a valley dissecting the mountain, creating the Bolshoye Goltsovoye and Maloye Goltsovoe lakes. The last eruption occurred at Kekuk Crater, about 7,200 years ago.
