Significant factors which determine the structure of terrestrial landscapes at mountain-orogen regions are latest and modern tectonical movements and gravitational slope processes. Those processes are well-spread at the territory of State National Reservation “Utrish”. Reservation is situated inside one of most active seismic areas of North-West Caucasus. The area is connected with Anapa protrusion where deep situated structures provide seismic events. Such structures are significant elements of the landscape and it determines different features of biocenose, controls the structure and functions of ecological systems. Thus research of paleoseismotectonical dislocations and landslides is an important step for description of natural objects of National Reservation. It allows to appreciate existing condition of objects and to predict trends of development in connection with natural and anthropgenical factors and finally we can offer best ways to preserve the environment here. Suddenly the problem of paleoseismotectonical dislocations and landslides was out attention regarding the territory of State National Reservation “Utrish”. Paleoseismotectonical dislocations and landslides, born by ancient earthquakes were well-known here before, but its structure and conditions of development were poorly studied. Its significance in the structure of terrestrial landscapes of National Reservation also was poorly studied. First experience in this direction was the contract “Identify paleoseismic fault scarps and landslides on the territory of the State Nature Reserve “Utrish” executed by us in 2014. Our researches shown, that presented area of Black Sea coast of Caucasus is one of most active areas regarding seismics and tectonics. Resent strong seismical events formed modern features of the landscape. Clastic substrate where grow unique plant communities have no close analogs in the World.

Key words: сейсмотектоника, сейсмогравитационные деформации, оползни, морфоструктуры, seismotectonic, seismogenic and gravitational deformations, landslides, morphostructures
