Landslide hazard assessment conducted for the site on the southern shore of the Taman Bay. Quantitative risk assessment is determined by the Mora- Vahrson method. The calculations assume that the landslide hazard is directly proportional to the susceptibility of the slope and the magnitude of the trigger factor. The susceptibility of slopes at the regional level is determined by such factors as: the vertical dissection of the terrain; the power of Quaternary deposits; the prevailing type of pre- Quaternary rocks; the depth of groundwater levels; the density of forest cover. The starting factor of landslide activity is: the intensity of atmospheric precipitation, the seismic score of the territory, taking into account the increment of seismic activity, the intensity of coastal abrasion (for coastal areas). On the basis of the obtained data, it was concluded that the studied section of the Taman Peninsula has the highest hazard class
