Other AbstractOn July 19,2018,a catastrophic soil landslide occurred in the Boli Village,Yanyuan County,Sichuan Province,and damaged 186 rooms of 65 houses,causing a direct economic loss of 13 million yuan. Due to the early detection of landslide from the visible cracks in the houses before the occurrence of the major landslide and the help of community-based early warning system,the dwellers ( 437 people in the region) were successfully evacuated with no casualties. Questionnaire survey,aerial photography and experimental analysis coupled with geological and precipitation data were analyzed for understanding its initiation process and deformation trends. Based on the detailed analysis,prevention and mitigation measures were proposed. The landslide is the result of the resurrection of the ancient landslide deposits under the influence of the steep fragile topography and the coupled action of precipitation and surface runoff. The landslide deposits still have the risk of being converted into debris flow hazards. The scientific rationality of the hidden danger points needs further research and confirmation. The landslide of Boli Village in Yanyuan County is a typical case of mass monitoring and prevention system with public participation. This system plays an important role in disaster warning and risk avoidance in geological disaster-prone areas in China. Through a good publicity and training about preliminary judgments on disasters,continuous inspections,notifications and application of self-help methods,it establishes a smooth communication network and provides favorable conditions for monitoring,early warning and risk avoidance of geological disasters such as landslides. The system in the study area can be divided into the county,township,village and group monitoring networks,which can provide future reference for similar disasters. Furthermore,engineering measures proposed should be considered to minimize further risk of the residual loose deposits at the trailing edge of the landslide deposits. The comprehensive control of the disaster body in this region should be improved.
