ROBUST MULTIMODAL IMAGE MATCHING BASED ON MAIN STRUCTURE FEATURE REPRESENTATION

Slope failures exist in many paraglacial regions and are the main manifestation of the interaction between debris-covered glaciers and slopes. We mapped paraglacial slope failures (PSFs) along the Hailuogou Glacier (HLG), Mt. Gongga, southeastern Tibetan Plateau. We argue that the formation, evolution, and current status of these typical PSFs are generally related to glacier history and paraglacial geomorphological adjustments, and influenced by the fluctuation of climate conditions.

We characterized the multi-decadal geomorphic changes of a low-angle valley glacier in the East Kunlun Mountains and assessed the detachment hazard influence. The observations reveal a slow surge-like dynamic pattern of the glacier tongue. The maximum runout distances of two endmember avalanche scenarios were presented. This study provides a reference to evaluate the runout hazards of low-angle mountain glaciers prone to detachment.
