Abstract

2D electrical resistivity tomography has been applied to a landslide investigation in Garhwal Himalaya. Three representative Wenner-Schlumberger profiles spanning the landslide are presented. Generally, resistivity tomograms show the presence of slip zones at a depth range of 10 to 20 m from ground level. The inferred lithological depth sections clearly outline the importance of resistivity tomography in landslide studies, especially in hazard assessment on a detailed scale.
