Mount Bandai erupted in 1888. A large part of the mountain body collapsed and slid down, which turned into debris avalanche. Three methods were applied to simulate this debris avalanche. They are Marker and Cell Method (MAC), Discrete Element Method (Ball Model) and 2-dimensional flow model. All methods show some good results by choosing appropriate parameters. Only data we have is resultant deposition. It is difficult to evaluate the simulated results. It is necessary to establish a more reasonable model.
