Sackung features (scarps) have developed extensively in the Japanese Alps as a result of gravitational deformation. Electrical resistivity tomography was applied to evaluate the internal structure below eight scarps located above 2600 m a.s.l. The range of resistivity values differed significantly between the scarps and is mainly controlled by the moisture content of the ground. High- and low-resistivity areas were distinctly separated below some scarps. Areas of relatively low resistivity are considered as slightly fractured bedrock. In contrast, areas of high resistivity are likely to indicate highly fractured bedrock and/or talus without matrix. Such boundaries between high- and low-resistivity areas seem to correspond to fracture planes estimated from topography.
