Integrated Geophysical Approach for Mapping an Active Landslide in Himalaya: A Case Study

A gravimetric survey was carried out over an active landslide area, followed by 2D multielectrode resistivity surveys in order to understand the present landslide in terms of failure surfaces and predict its future behavior. Preliminary gravity survey has delineated a number of failure surfaces or faults within the active landslide zone and its neighboring area. The electrical resistivity profiles were conducted across the inferred faults lines for confirmation and for deciphering subsurface lithology.
