To reduce damages of recurrent disasters of landslide in moutainside towns, a constant awareness of the disaster prevention is important. A dynamic and visual representation of a disaster would play an effective role to explain a danger of a landslide disaster. In the present study, numerical simulation of a landslide was performed using the three-dimensional Distinct Element Method, and an eloquent performance of this kind of simulator was represented by showing various angle of snapshots. Especially, a landslide considered with fallen trees modeled by the passively-moving-solid model was simulated because a usual landslide disaster contains fallen trees, and the simulation result showed a good agreement with an actual landslide in a tendency of accumulation form.
