| Abstract | Due to global climatic warming, the possibility of collapse of polythermal glaciers is increasing. In the summer of 2016, two massive glaciers suddenly collapsed at Aru Village, Ali District, Xizang Autonomous Region, China, running out up to 7 km and killing nine herders. These events occurred suddenly in a remote area, and quantitative data about them was difficult to obtain quickly. Their seismic waves, however, could be quickly inverted to estimate the event motion parameters; the inversion results reflecting the average state. In order to have an initial judgment on the deposit range and the kinematic parameters at different positions after the collapse, seismic-wave inversions were used to estimate parameters (e.g., mass and friction coefficient) for numerical simulation to quickly simulate the motion processes that are important for the initial rescue, especially in the absence of topographic data. Numerical simulation showed that even though the shape and depth of the source area as assigned from such inversion were slightly different from the real situation, the effect on the final deposit morphology was not so great, which can be used as a reference for useful assessment after future disasters. |
