- Аннотация: Database of large-scale bedrock landslides of the Central Asian region embracing the Pamir, the Tien Shan, and the Dzungaria mountain systems has been compiled. Collected rockslides range in volume from nearly 1 x 106 m3 to ca. 10 x 109 m3 with the affected areas from several hectares to more than 100 km2. More than 950 landslide features have been identified and quantitative parameters (area of the deposits, total area affected, volume, runout, height drop, etc.) of about 62% of them have been measured up to now. Most of case studies are prehistoric. Statistical analysis of this database with regard to the confinement conditions demonstrates that total affected area and its ratio with height drop characterize rockslide mobility better than runout and angle of reach. Higher mobility of secondary rock avalanches associated with momentum transfer within rockslide debris in comparison with rock avalanches of other types is confirmed statistically. These results can be useful for landslide hazard assessment both in Central Asia and in other mountainous regions.
