Abstract
This paper examined typical examples of slope failures that occurred during the past 15 years in Mie prefecture, clarifying the features of slope failures controlled by geology. Sedimentary rocks and schists have been subjected to landslide with planar sliding surfaces parallel to their foliations. On their anaclinal slopes, toppling has occurred. Igneous rocks have been subjected to destructive slope failures, if they are severely weathered or fractured with adversely oriented joints. Decomposed granite in the Ryoke Belt has been subjected to compound slide. Large rockfalls and slope failures may occur in granite porphyry of the Kumano acidic rocks, in which columnar joints are developed. Weakly consolidated lake deposits have been subjected to landslide with low angle sliding surfaces parallel to the bedding plane.
