Abstract
The main goal of the study was to determine the places of modern landslides and investigate the geomorphological and geological setting, and other causes of these natural hazard processes. The area of research is located in Outer Carpathians nearby fault between Skyboviy and Boryslavsko-Pokutskiy thrusts. This location determines the development of numerous tectonic zones of rocks deformation related to thrusts formation. The detailed study was curry out along Pystynka river in Kosmach village. As a result, we described series zones of deformed rocks both folded and crashed. In each causes the present exogenous processes are more developed and in several places related to small modern landslides. The most potential places for developing natural hazard processes are sub-vertical axial plane of folds and zones of crashed claystone. Calculated trends and plunges of stress axes detected that the main movements of thrusts had both vertical and horizontal amplitudes.
