Between July, 14 and September, 20, 2002 in the area of Mt. Kazbek(the North Caucasus) debris and ice surge happened from Mt. Dzhimarai-Khokh (the information was received from Lev Desinov, Institute of Geography, Russian Academy of Sciences). On September 20, the collapse of a hanging glacier from the slope of Mt. Dzhimarai-Khokh onto the Kolka Glacier below triggered an avalanche of ice and debris. The avalanche buried the mountain village of Karmadon in the Russian Republic of North Ossetia, killing dozens of people. The Prikazbeksky area of the Big Caucasus where catastrophe happened, is the zone of natural disaster such as earthquakes. In seismic areas all abnormal phenomena are usually connected with particular earthquakes considered as an original cause.

In given work the analysis of seismic activity of area of Mt. Kazbek against the background of seismicity of all Caucasus is submitted. Spatial and temporal distributions of seismic events for Mt. Dzhimarai-Khokh since historical times up to now is analyzed. In conclusion the results of processing analog and digital seismograms on which records of the ground motion caused by movement of a glacier are registered are given.
