Abstract

This paper reviews recent case studies completed on mass movements with probable co- seismic origin in the Uzbekistan part of Tien—Shan, Central Asia. Landslides, as any geological phenomena, formed due to simultaneous action of exogenous and endogenous forces. We consider simultaneous formation in the different areas of large landslides caused by the influence of these forces as a trigger effect. The nature of this connection, it is not only change of tectonic stress field, but at the same time the impact of climatic factors, the movement of groundwater, as well as the value of the natural frequency of oscillations in landslide-prone slopes. In this paper we consider the natural frequency of landslide-prone slopes in comparison with maximum spectral frequency of long-acting low-frequency oscillations of Hindu Kush earthquakes which caused major landslides in 2015 and spring 2016.
