Landslide Risk Assessment, Management, and Reduction for City Territories

Abstract

Geological and landslide risk management can be viewed as a series of events leading to landslide risk reduction, including risk analysis, risk assessment, risk mapping, vulnerability evaluation, the concept of acceptable risk, monitoring organization, engineering-technical methods, insurance, and others. This chapter describes the methodology for landslide risk assessment and mapping in urban areas. The construction of a landslide risk map in a territory of Moscow is proposed. Based on preliminary expert estimates, areas with high landslide risk are in the vicinity of the Moscow and Yauza Rivers, as well as in areas of contrasting relief along riverbeds of paleochannels in the city center. These areas may be considered “hot spots” on the risk map.
