Rockslides and Rock Avalanches of Central Asia: Distribution, Impacts, and Hazard Assessment arms scientists with an inclusive and specialized reference for future studies of large-scale bedrock landslides in Central Asia, a phenomenon that poses a major threat to local communities, infrastructure and industrial facilities. The book covers the Dzungaria, Tien Shan, and Pamir mountain systems that are characterized by arid climates and scarce forestation, and is an ideal reference for scientists searching for data that accurately summarizes bedrock landslides through the analyses of a multitude of case studies that have applications in comparable, global scenarios. Through its relatively low precipitation and good preservation of minor geomorphic features, particularly those formed by past landslides, this region provides opportunities for detailed study of the internal structure of landslide bodies.
