From Wikipedia

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