The experimental results of determining the sliding surface of landslides in field experiments in the North Caucasus by the method of ultra-wideband monopulse radiolocation by using GPR ""GROT-12"" were received. The prospects for the use of advanced technology for the assessment of the power of the strata that cover the surface of sliding rock mass forming the body of the landslide are discussed. It is shown that the proposed technique allows to estimate the body volume of potential natural and man-made landslides.
