Kozelsky Volcano

Avachinsky

Stratovolkan · Russia · 2717 m

Avachinsky rises above Petropavlovsk, Kamchatka's largest city. The peak to the right is the rim of a large horseshoe-shaped crater that formed during flank collapse about 30,000-40,000 years ago and produced a major debris avalanche buried an area of about 500 km2 to the south, underlying the city of Petropavlovsk. The modern cone was constructed inside this crater. Frequent historical eruptions have been recorded since 1737.

Ringkasan geologi

Avachinsky, one of Kamchatka's most active volcanoes, rises above Petropavlovsk, Kamchatka's largest city. It began to form during the middle or late Pleistocene, and is flanked to the SE by Kozelsky volcano, which has a large crater breached to the NE. A large collapse scarp open to the SW was created when a major debris avalanche about 30,000-40,000 years ago buried an area of about 500 km2 to the south, underlying the city of Petropavlovsk. Reconstruction of the volcano took place in two stages, the first of which began about 18,000 years before present (BP), and the second 7,000 years BP. Most eruptions have been explosive, with pyroclastic flows and hot lahars being directed primarily to the SW by the collapse scarp, although there have also been relatively short lava flows. The frequent historical eruptions have been similar in style and magnitude to previous Holocene eruptions.

Avachinsky is an active stratovolcano in Russia. It is situated on the Kamchatka Peninsula in the Russian Far East. Avachinsky lies within sight of Petropavlovsk-Kamchatsky, the capital of Kamchatka Krai. Together with neighbouring Koryaksky volcano, it is considered a Decade Volcano, worthy of particular study in light of its history of explosive eruptions and proximity to populated areas.
