Quantitative Analysis of Landslide and Debris Flow Based on Seismic Signal

Landslides and debris flows are occasionally explosive and extremely destructive. In recent years, satisfactory results have been made in studying these hazards based on environmental seismology and using seismic signals to monitor and analyze the evolution of hazards. In this study, the quantitative analysis of landslide and debris flow based on seismic signals is summarized and analyzed. It includes the analysis of seismic signal characteristics of different hazards, the reconstruction analysis of landslide, debris flow and hazard chain, and further combined with the dynamic inversion of seismic signals and numerical simulation method, the reconstruction method system of hazards evolution process is constructed. In view of the current research progress, the direction of future research is proposed. These methods provide new ideas for the study of landslides and debris flows, and provide theoretical guidance for future monitoring and early warning and hazard prevention and mitigation.
