Predisposing factors in debris flow and thinkings of disaster assessment

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.
