The purpose of this study to analyze landslide-triggering factors using the 38 landslide cases occurred by typhoon, Rusa in 2002, Maemi in 2003 and Ewiniar in 2006 and geospatial characteristics in Hamyang and Geochang County. where two day's heavy rainfall was concentrated on. The rainfalls factors to trigger landslides were accumulative rainfall (>230mm) and rainfall intensity(>30-75mm). The highest landslide frequency was concentrated on the areas of 400-900m in height and on the slopes of $25-40^{\circ}$ in degree. The frequency of landslide was high exceedingly above 80% of a slope attitude, while the frequency is very low below 70%. Granite was more susceptible as much as 9 times than metamorphic rocks. In areas mixed soil with gravels and rock blocks, the frequency of landslide was 73%.
