... earthquake which occurred in China is such an example. The massive Daguangbao landslide is the largest landslide that occurred in this earthquake and it is modeled in this paper suing a 3D using the Material Point Method (MPM). Focus is on the failure mechanism and the run-out process of the failed mass due...
