摘　　要：Glacier-related slope failures,including ice avalanches,ice-rock avalanches,glacier collapses,and rock avalanches on glaciers,are generally characterized by large collapse volumes,solid-liquid phase transition,and high mobility[1].They are one of the major types of geo-hazards in high mountain areas.Glacier-related slope failures have cascading effects since they often evolve into glacial lake outburst floods(GLOFs),debris flows,and dammed lakes,which significantly prolong and amplify the impacts of the hazard.Tragic slope failures have cumulatively claimed more than tens of thousands of lives.For example,the 1962 and 1970 Huascaran events in the Peruvian Andes caused approximately 20,000 deaths[2],and the 2021 Chamoli ice-rock avalanche in the Indian Himalayas left more than 200 people dead or missing[3].
