In steep mountainous regions, landslides may include both soil and underlying weathered bedrock (hereafter, —deep catastrophic landslides•). The method for assessing susceptibility to deep catastrophic landslides, originally developed for landslides caused by heavy rain, was tested in this study against historical landslides caused by the Iwate and Miyagi inland earthquake of 2008. The method proved to be capable of independently identifying catchments in which deep catastrophic landslides occurred with fair accuracy.
