Abstract
Glacial stability on the Tibetan Plateau has declined sharply in the context of global warming. Previously, continental glaciers on the northwestern Tibetan Plateau were considered stable and had little susceptibility to ice collapse. However, in recent years, numerous continental glacier ice collapses have resulted in significant economic losses, casualties, and ecological environmental damage. This study focused on eight watersheds in the Ngari Prefecture of the northwest Tibetan Autonomous Region, specifically in the upper reaches of Zecuo Lake. Continental glacier ice-avalanche disaster factors were examined based on topography, climate, and geological structure. This study proposes a continental glacier ice-avalanche susceptibility assessment method that considers both internal and external factors by combining the analytic hierarchy process (AHP) and cloud theory. A comprehensive evaluation and analysis revealed that the eight watersheds in the upstream study area of Zecuo Lake were greatly affected by climate change and geological structure, and the susceptibility assessment ratings for all glaciers were high. Therefore, it is essential to strengthen the monitoring and early warning systems in areas of human activity. The findings of this study provide a scientific basis for predicting, preventing, and mitigating continental glacier avalanche disasters on the northwestern Tibetan Plateau. Additionally, the proposed method can be applied to areas with similar geological conditions.
期刊介绍：
Landslides are gravitational mass movements of rock, debris or earth. They may occur in conjunction with other major natural disasters such as floods, earthquakes and volcanic eruptions. Expanding urbanization and changing land-use practices have increased the incidence of landslide disasters. Landslides as catastrophic events include human injury, loss of life and economic devastation and are studied as part of the fields of earth, water and engineering sciences. The aim of the journal Landslides is to be the common platform for the publication of integrated research on landslide processes, hazards, risk analysis, mitigation, and the protection of our cultural heritage and the environment. The journal publishes research papers, news of recent landslide events and information on the activities of the International Consortium on Landslides.
