Climatic and morphostructural conditions of the large landslides genesis in the Great Caucasus

Abstract

Gravitational dislocations of different scale formed in different climatic epochs occur in the Great Caucasus. Intensification of gravity induced processes took place during periods of high precipitation. It is reliable that in the future earthquakes will more frequently cause large landslides and rock falls due to growth of precipitation and temperature recently observed in this region. Holocene and recent processes of this type are often situated close to morphostructural junctions, as may be seen from comparison with special morphostructural scheme of the Great Caucasus. The most part of gravitational displacements occurs in the high seismic junctions. Some of displacements have appeared without seismic events in the aseismatic junctions.
