To develope a method for assessing the potential of slope failures during earthquakes, we proposed a simple method to map the potential of slope failures during earthquakes using Digital Elevation Model and potential earthquake wave data. In the developed method, slope gradient, mean curvature and peak ground acceleration were used to evaluate the relative potential of slope failures. Here we examined the applicability of the method to Niigataken Chuetsu Earthquake, 2004. The analyses showed that the proposed method is an useful tool for assessing the relative potential of shallow slope failures triggered by Niigataken Chuetsu Earthquake, although the proposed method is not effective to predict the location of deep seated landslide during earthquake.
