The result of the study on the Mushigame landslide which occurred in 1980 can be summarized as following lines (FUJITA, Y. et al 1981); 1. The sliding plane near main scarp has developed not within the bed rock of Miocene Shiiya formation, but in the older landslide debris deposit. 2. The normal faults (lunar fault crack) have developed in this older debris mostly behind the crown of the main scarp. These faults have been formed prior to the sIiding (Fig. 2). 3. The older debris deposits might fall down along these faults and the landslide was brought about in succession (Photo. 1). 4. Before sliding, we can frequently recognized the graben-like small valley behind the scarp. Those features are also recognized at the other recently sliding areas such as the Nigorisawa, Kamibanba, Nakamaruke in Niigata Prefecture and Showa-mura and Yamato-machi in Fukushima Prefecture. Therefore, we emphasize the importance of discovery of above-mentioned features; namely fault, or crack, graben in landslide areas, for prediction of hazardous sliding area. Figure 10 shows a hazard map in Yamakoshi-mura, from the above-mentioned standpoint.
