Abstract: Through the application to the landslide events in the Mt. Dalbong area about 78 kilometers south from Seoul, occurred during a heavy storm in 1991, SINMAP successfully spotted most landslide sites. The effects and proper ranges of three calibration parameters of SINMAP, i. e. soil friction angle, cohesion, and T/R, were examined through comparison in predicted landslides with the landslide inventory data. From the findings of this study, it seems that SINMAP could be used as an effective screening tool for landslide hazard mapping especially for mountain areas with fairly steep slopes and relatively thin soil layers.
