Abstract: The main factors inducing debris flow landslide into a rapidly moving fluid, volcanic eruptions and rainfall intensity is large, volcanic flows and rapidly melting snow and ice with a combination can lead to debris flows. Earthquake and dam break could result in the occurrence of landslides. A comprehensive assessment of debris flow disaster occurred at a time to pay attention to debris flow, landslides had occurred, mudslides and landslides sliding scale from the other major issues. In-depth understanding of predisposing factors and movement of debris flow disaster law, is the basis for development of mitigation technologies.
