Koryakskaya Sopka or Korkatsky is a volcano on the Kamtchatka peninsula in the Russian Far East. This volcano is 11,300 feet (3,400 m) high. The peak of the volcano has a modern crater, 590-650 feet in diameter. The volcano is located only 22 miles (35 km) from the territory's capital, Petropavlovsk-Kamchatsky and contributes to the panoramic views from the city.
In 1996, this volcano was listed as a Decade Volcano, one of 16 volcanoes around the world that the UN International Association of Vulcanology and Chemistry of the Earth's Interior found deserving of special study because of their history of activity and proximity to modern-day settlements.
In December 2008, Koryakskaya Sopka emitted a column of steam and gas that could easily be seen in photographs taken from space. Its most recent eruption was recorded in 2009.
