Methodical approaches of geophysical research of landslide areas

Abstract

Summary Significant territories of Ukraine require risk assessment of dangerous natural and man-made phenomena and processes that are a threat to the safe living environment and the functioning of objects of economic infrastructure. The landslides relate to the category of the most dangerous and widespread exogenous geological phenomena. Owing to cyclic recurrence and disastrous manifestations of landslide processes, they create a permanent threat of man-made, natural and man-made-natural emergencies. The experience of geophysical studies of landslides shows that they are extremely heterogeneous in all its indicators both in terms of area and depth. The landslide body is characterized by anisotropy of all geophysical parameters. At the basis of this phenomenon is a fracturing of rocks, which is one of the most characteristic features of landslides. These factors increase the requirements for the geophysical research methods of landslides. The rational set of geophysical methods in the study of landslide processes is determined for each individual natural situation. Thus, it is taken into account: the possibility to apply a specific geophysical method in terms of relief of the surface; the presence of differentiation of physical properties of rocks; the economic efficiency and the importance of tasks.
