Due to the impact of 1999 Chi-Chi Earthquake (MW=7.6), the geology in Taiwan area was more fractured and a tremendous amount of landslides were induced. After 1999, the unusual typhoon events cause the primary and secondary landslide hazard more severe. This study aims to study the landslide hazard by the SPOT satellite images, focusing on the behavior of the primary and secondary landslide hazards after 1999. In order to obtain the landslide distributions efficiently, this study adopted an NDVI-Slope criterion in the GIS image interpretation. Since this criterion could be affected by local topography ore geology, it could be necessary to adopt different criterion for different catchment or sub-catchment. In this study, the Wu His catchment in Central Taiwan was adopted as study area, the landslides induced by three typhoon events, i.e., Herb (1996), Toraji (2001) and Mindulle (2004), were analyzed. In order to obtain an optimal criterion, the analysis of Receiver Operating Characteristic Curve was used. The results showed good interpretation by using the criterion 0.1 of NDVI and 40% of slope in Wu His catchment, for the whole catchment and for its sub-catchments. The landslides distributions showed that significantly more landslides were induced near the Chelungpu Fault by the 2001 Toraji Typhoon. In addition, more landslides were found in the upstream Peikang River sub-catchment, due to the distribution of heavy rainfall. However, less landslides were induced by 2004 Mindulle Typhoon in the Peikang River area, since the heavy rainfall is distributed in the northwestern side of the catchment. The results reveal that the self-healing effect is undergoing, but subsequent typhoon events could still cause above-normal landslides. However, the impact of landslide will decay away gradually.
