Electrical and seismic methods are used to obtain the information needed to determine slope stability. Experience has been gained from long-term investigation carried out in various regions of the Soviet Union. Applications include evaluating geologic and hydrologic conditions related to the occurrence of landslides. Primary attention is devoted to the study of landslide slopes proper. The geologic structure of a landslide is considered in modelling it and determining the thickness of both the landslide body and the slip zone. The methods of self-potential, resistivity, and temperature measurements are analyzed for characterization of the seepage flow through the landslide body. Useful engineering properties of soils may be obtained from field and laboratory geophysical measurements and measurement of changes of geophysical parameters with time are significant in assessing changes in the states of landlside soils. Observation of the direction and velocity of landslide movements is possible with mangetic and electrical methods. Examples of geophysical investigations of landslides in the Crimea, on the Black Sea coast of the Causcasus, and in the Volga River Valley are presented. The study concludes that the application of geophysical methods to the investigation of landlside phenomena makes it possible to solve several problems, the most significant of which are: Determination of the geometry of landslides and the water saturations assessment of the physical properties and states of the rocks comprising the the landslide; and the study of the motion of landslide mass.
