In different places, including Kuban, landslides, floodings, mudflows and floods constantly occur. The reason is the change in the rheology of materials, initially solid deformable media, which are water-saturated and the block structure ceases to be resistant to deformation, which causes redistribution of stresses and destruction. Just as it happened with the discovery of starting earthquake using the block element method, this method can be effective in studying block structures from media of rheology other than elastic, and help to detect precursors of destruction of structures causing landslides, floodings and mudflow processes more effectively than others. The formation of landslide structures, as a rule, is caused by water saturation of the lower layers of soils having elastically deformable coatings, hiding the actual deep processes and preventing the destruction of the block structure. As soon as the process of destruction of the top coating begins, there is a danger of landslide processes. This phenomenon has been little studied and is the object of research in this paper. It was consider the model of membranes for imitating the coatings.
