oa Landslide hazard assessment and forecast of landslides within territories of the southwestern outskirts of the East European Platform,the Pre-Carpathian Deflection and the Carpathian region of Ukraine

The development and prevalence of landslides within territories of the southwestern outskirts of the East European Platform, the Pre-Carpathian Deflection and the Carpathian region of Ukraine are explained by geological, structural-tectonic, lithological-stratigraphic and geomorphological features, neotectonic, hydrogeological and seismic regimens, as well as the degree of technogenic impact. The activity of the landslide process is closely related to precipitation and temperature regimes, changes in groundwater levels, etc. Activation of landslides is often associated with the development of other exogenous processes (erosion, flooding).

Within the abovementioned geostructural regions, geological processes differ in intensity, dynamics and area of distribution, which is associated with conditions of their development.

Forecasting changes of the state of geological environment consists of forecast estimates of separate geological processes, on the one hand, and forecast estimates of the stability of geological environment as a result of technogenic changes in natural-technogenic systems of different ranks, on the other hand. Landslide forecasting is conducted from the standpoint of systematic approach. The implementation of this approach allows to identify a complex of links that reflect the direction of development of natural-technogenic systems according to the following aspects: stability of the geological environment (subsurface part of the lithosphere) under the influence of external agents, including technogenic activities; adaptation of natural-technogenic systems in their development; self-regulation of the natural-technogenic system given changes or stability of external influence.
