A lot of landslides distribute around the area of intrusive rocks, caprocks and so forth. In this paper relationship among slope angle, geology and landslide occurrence in this area is discussed. It becomes clear quantitively that relative frequency of landslide occurrence is heigh around areas of intrusive rocks and caprocks. With this results, a landslide hazard zonation method using slope angle and geology is proposed.
