| Abstract: | Mountain glacier-related hazards occur worldwide in response to increasing glacier instability and human activity intensity in modern glacierized regions. These hazards are characterized by their spatial aggregation and temporal repeatability. Comprehensive knowledge about mountain glacier-related hazards is critical for hazard assessment, mitigation, and prevention in the mountain cryosphere and downstream regions. This article systematically schematizes various mountain glacier-related hazards and analyzes their inherent associations with glacier changes. Besides, the processes, manifestations, and mechanisms of each of the glacier-related hazards are summarized. In the future, more extensive and detailed systematic surveys, for example, considering integrated ground-air-space patterns, should be undertaken for typical glacierized regions to enhance existing knowledge of such hazards. The use of coupled numerical models based on multi-source data is challenging but will be essential to improve our understanding of the complex chain of processes involved in thermal-hydrogeomorphic glacier-related hazards in the mountain cryosphere. |
