Abstract: Knowing the reaction in time of slopes proves a difficult approach, which combines geological field investigation methods, methods of assessing physical and mechanical rock. They allow the development of evolutionary models of phenomena and processes that contribute to diminishing the stability of slopes. Distribution of landslides is according to geological age of some relevant fundamental elements with a constant frequency. Correlation frequency of landslides with slope values found an increased frequency of slopes to the foot slopes, where there is a multitude of factors of instability. Analysis of landslide distribution in space of flysch and internal foredeep in Carpathians determines a specific focus on alignments, which incidentally relate to the tectonic fractures, usually crossing the general geological structure. It defines the importance of tectonic factor in assessing and forecasting the stability of slopes. In areas affected by tectonic fractures are f!
ound to accelerate the processes of rock alteration, which causes a reduction of the resistance forces on the one hand, and growth of gravitational instability on the other. Also, faults and their surrounding areas favor the movement of groundwater, contributing to an increased gravitational instability.
