Deep catastrophic landslides often caused serious damage. However, there is no widely used method for estimating spatial patterns of deep catastrophic landslide susceptibility. In the last several years, we studied about deep catastrophic landslides. First, we examined roles of bedrock geology and rock uplift rate on regional frequency of deep catastrophic landslides. Next, we proposed a new method to estimate landslide susceptibilities for many small catchments (ca. 1 km^2) over relatively large areas (ca. hundreds of km^2). Finally, we presented a new implantation method for large-scale debris flow triggered by deep catastrophic landslide. We combined several approaches, including historical data analysis, aerial photograph interpretation, geomorphological and geological surveys, statistical approach, numerical simulation etc. to provide these new methods. Here we synthesized these recent advances about methods for assessing the susceptibility of disasters induced by deep catastrophic landslide.
