Abstract:The Tibetan Plateau is the area with the most active interlayer interactions,the strongest coupling effect of internal and external forces,the most sensitive to global climate change,and the most intense geological hazard activity,which is characterized by significant synergism of tectonic-climatic-geohazards and globally recognized as a natural laboratory for studying rock avalanche dynamics.To explore the extremely high mobility of rock avalanches,our team has been dedicated to the geological investigation and dynamic analysis of rock avalanches in the Tibetan Plateau and its adjacent areas for many years.Based on the previous study,it first elucidates the terminological origin and the main characteristics of rock avalanches.Subsequently,the new discoveries,understandings and perspectives reached by the team based on more than two decades of systematic research on rock avalanches across the Tibetan Plateau is introduced,i.e.,revealing the essence of rock avalanche volume effect,proposing the new viewpoints that rock avalanche should be a cataclastic flow,proposing the self-excited vibration effect,and building the emplacement models of rock avalanches under varying conditions.The finding and proposition of these achievements systematically exhibit the research paradigm from field geological observations to theoretical framework establishment for rock avalanche dynamics.Finally,it summarizes critical insights for rock avalanche study based on previous work,hoping to provide scientific references for advancing rock avalanche research and formulating corresponding risk mitigation strategies.
