Frictional shearing along the basal slip surface is the main energy dissipation mechanism in coherent landslides, which undergo little internal deformation during runout. Most landslide bodies, however, deform and break down more or less extensively; thus, only a portion of their potential energy is dissipated through basal shearing. The mineral components of rocks and soils have individual melting temperatures. Therefore, as temperature increases, selective melting will occur in a defined…

Sedimentological characteristics and thermal metamorphic rocks in deposits can provide clues regarding the frictional melt processes of ancient rockslides; however, the quantitative dynamic
MPM evaluation of the dynamic runout process of the giant Daguangbao landslide
Giant landslides can cause significant damage to their dynamic runout processes. Understanding the mechanics of the runout process is essential for landslide risk assessment and mitigation design.
