The run-out zone and risk elements subjected to the landslide are not well considered. Despite of the identification of landslide slipping area, the direct or indirect effects to the deposition area in the mapping of sensitive landslide cases cannot be ignored after several large landslide incidences such as Tsao-Ling, Ju-Fen-Err mountain, and Tu-Chang cases. It is obvious that both the potential landslide area and run-out zone should be considered as landslide susceptible area. Researches on potential landslide areas had been conducted by adopting the environmental factors such as geomorphology and geology and the disaster-triggering factors such as torrential rain and earthquake. The key point of landslide run-out mapping is based on the scenario simulation, and the risk assessment from scenario simulation is the essential procedure for mapping of landslide susceptible area. Owing to lacking of systematic research on the scenario simulation and risk assessment of potential landslide areas in Taiwan, four sites with significant landslide potential have been selected for research starting from 2007 for 4 years. The major works include field investigation, field monitoring, landslide scenario simulation and risk assessment etc. The results of the research will provide important information for other potential landslide cases and mapping of susceptible area.潛勢範圍堆積區境況模擬風險評估監測potential arearun-out zonescenario simulationrisk assessmentmonitoring
