抄録

This paper describes an applicability of morphological operations for slope failure detection using low resolution remote sensing imageries. The distribution of remote sensing data on the failure area is formulated using diffusion equation based on the distribution of collapsed soils. The equation is presented by gray-scale morphological operations. The method is applied to the detection of slope failures triggered by the Hyogo-ken Nambu Earthquake. As the result, the reliable sizes, shapes and morphological types of the failures are computed with the accuracy of 75%. By using the parameters which have used in above case study, the method is also applied to failures caused by heavy rainfall after the earthquake. The results show the applicability of the method for time series monitoring using satellite imageries.
