Mount Kazbek
The Kolka–Karmadon rock-ice slide occurred on the northern slope of the Mount Kazbek massif in North Ossetia–Alania on 20 September 2002, following a partial collapse of the Kolka Glacier. It started on the north-northeast wall of Dzhimarai-Khokh, above sea level, and seriously affected the valley of Genaldon and Karmadon. The resulting avalanche and mudflow killed 125 people (including a film crew of 27 people, among them Russian actor Sergei Bodrov Jr.). While this type of avalanche is not uncommon this particular event is considered extraordinary because of several aspects.
