Features and assessment of landslide hazard in Moscow

An analysis of domestic classifications of landslide processes is carried out including the study of various as pects of this phenomenon. Special attention is paid to such parameters as the mechanism of landslide manifestation, landslide morphological characteristics, prevailing slope factors, degree of rock stability loss, as well as landslide location, structure and shape in the plan. The manifestation conditions of deep and surface landslides on the territory of the city of Moscow are studied. The results of an expert survey, on the basis of which taxonomic features have been identified, are presented. The classification of factors according to the activity degree of landslide sites in Moscow has been compiled. The purpose of the study is to generalize and systematize the main taxonomic units of landslide processes developed on the territory of Moscow as well as to identify uniform regular features and taxa of the studied process. The article discusses analytical methods for identifying taxonomic units of domestic landslide classifications and their application potential for Moscow region landslide processes. The object of the study is Moscow landslides. The subject is the study of factors and conditions influencing the activity of landslide processes. Conducted expert assessment made it possible to distribute the factors and conditions according to their impact degree on landslide site activity in the territory of Moscow. As a result, 25 factors (“type” taxon) affecting the condition of the slope and distributed by classes of conditions (the total number is 9) have been identified. Several classes have been combined into a taxon with a higher rank (group). The compiled classifi cation features 3 groups distinguished according to the duration of the factor’s impact on the landslide slope.
