Abstract
Using the example of the Voronezh region as an old-developed flat region, methodical aspects of risk analysis are considered, including the identification, mapping and typology of landslides, identification the conditions of the landslide processes development and determination of the general characteristics of its hazard. Over 1700 landslides were revealed and mapped; a specialized geo-information system was compiled. The use of the GIS combined with the digital elevation model made it possible to determine the general regularity of spatial distribution of landslides, to clarify some parameters of its morphometry and territorial organization. Attention is focused on step-by-step approach to the assessment of landslide hazard and the identification of genetic types of landslides, which differ in structural, functional and dynamic features. The map of the landslide hazard levels of the landscapes of the Voronezh region has been compiled; it is based on a joint analysis of the density of landslide and the distribution of slope landscapes. The map made possible to identify regions with a low, medium and high degree of landslide hazard.
