Preliminary Surveys of Resistivity near the Reservoir of Takadomari in Hokkaido

Abstract

All places surveyed are included in the zone of serpentin. Almost all hills are slided and collapsed and they have no big tree. The reservoir is being filled with a large amount of slided materials. Four places were chosen along the road for the present survey where some special features of the land-slide were respectively observed and resistivities of serpentin could be distinguished from that of the other material. We have had such a conclusion ac that the resistivity method will be useful for the survey of the land-slide in this district.
