In this study, we clarified the factors which highly relate to the occurrence of collapse by jointly applying the image overlay method and quantification method on the places where the collapse occurred at the surface layer in the past. We also discussed the necessity to analyze the hazardous places where the collapse is anticipated occurring at the surface layer in the future, respectively for each pattern of occurrence. We could obtain the following findings through this study : (1) The collapses in the study area caused by the same reason (124 places) could be roughly classified into 6 patterns. (2) By employing the analysis method with which image overlay method and quantification method were jointly used, we were able to surmise the relation between the location of past collapses and hazardous places where the collapse is anticipated in the future.
