Evaluation of rainfall-induced landslide transit characterization

As landslide hazard has intensified in the past decades, the development of landslide hazard evaluation systems has become more and more important. However, not much attention is paid to discussing the landslide transition in new and reoccurring landslides between different triggering events. A region in the central Taiwan, the Chenyulan River basin with the landslides from three typhoon events, Typhoons Toraji, Mindulle and Sinlaku, is selected for landslide hazard analysis in this study. The Rainfall-induced Landslide Hazard Rating System is developed and applied in the landslide transit characterization analyses. The results show that landslide transit characterization varies according to geological and topographic factors in the study area. More importantly, locations with preceding landslides, regardless of occurrence time, are vulnerable to landslide reoccurrence. A systematic procedure of landslide transit characterization is developed in this study, which ultimately can provide additional information for future planning and design of landslide alarm system.
