Abstract

A pit survey, near-surface ground-temperature monitoring, DC resistivity tomography, and an eighteen-year interval survey elucidate the internal structure and the recent movements of the active protalus rampart in the Kuranosuke Cirque, the northern Japanese Alps. Permafrost was found beneath the lower part of the protalus rampart by using ground temperature monitoring and DC resistivity tomography. The results of DC resistivity tomography suggest that the materials of the protalus rampart has a at least 15 m in thickness. Four targets placed on the lower part of the protalus rampart moved at mean horizontally rates of 2.4 to 7 mm a^-1 between 1983 and 2001. These displacements probably occurred due to permafrost creep and/or deformation in the lower part of the active layer.
