2002 Kolka-Karmadon rock-ice slide

A firn massif and the body of the Kolka Glacier collapsed in North Ossetia on 20 September 2002 and ran down the Genaldon Ravine, with the speed of the movement later calculated from seismic records. Researchers publishing in Russian Journal of Earth Sciences assumed the initiating cause to be a seismic effect that produced fumarolic emanations beneath the firn field in July 2002, two months earlier, followed by its gradual destruction as thermokarst developed. The volumes of the collapsed firn and glacier were also calculated.
