Koryaksky or Koryakskaya Sopka (Russian: Коря́кская со́пка) 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 has been designated a Decade Volcano, worthy of particular study in light of its history of explosive eruptions and proximity to populated areas.
Koryaksky lies on the Pacific Ring of Fire, at a point where the Pacific Plate is sliding underneath the Eurasian Plate at about 80 mm/year. A wedge of mantle material lying between the subducting Pacific Plate and the overlying Eurasian Plate is the source of dynamic volcanism over the whole Kamchatka Peninsula.
The volcano has probably been active for tens of thousands of years. Geological records indicate that there have been three major eruptions in the last 10,000 years, at 5500 BC, 1950 BC and 1550 BC. These three eruptions seem to have been mainly effusive, generating extensive lava flows.
