High mountains are increasingly prone to natural hazards such as avalanches, flash floods, landslides, and newly emerging glacier-related hazards. Glacier ice avalanches present an immediate hazard but can also lead to more serious secondary hazards by forming dangerous sediment-dammed lakes or causing floods by breaching natural or constructed dams. A recent flash flood in the Indian Himalayas caused by an avalanched hanging glacier took many lives and destroyed two hydroelectric power plants. After performing a preliminary analysis using remote sensing datasets, the surface velocity of the glacier is shown to have had anomalous values before the event. In order to further extend this analysis, our project will compile a timeseries of satellite data for this and similar events in the valley to estimate related surface velocity changes. The results of this pilot study will improve our understanding of ice avalanche processes.
