Abstract
Many previous studies reported that the several geomorphological and geological features were often found at the area close to scars of catastrophic landslide based on detailed field survey. However, most of these studies focused on only areas close to catastrophic landslide scars, and very few studies paid attention to the areas where the catastrophic landslide did not occur. In this study, we quantitatively analyzed the positional relationship between catastrophic landslides and geomorphological and geological features, such as mass rock creep, deep-seated landslide (rotational), arc-shaped crack, gentle ridge top, active fault and geological fault at Mt. Wanitsuka in Miyazaki Prefecture. We confirmed that these geomorphological and geological features, which has been often found at areas close to catastrophic landslide scars. And, some of these features, including geological fault, deep rotational landslide, gentle ridgetop, were appeared not only at areas close to catastrophic landslide scars but also at areas far from it.
