Abstract

A geophysical investigation was applied to an area, subjected to a large active landslide in the region Naitwar, Uttarakhand, India. The joint application of electrical resistivity tomography (ERT) and gravity studies has led to the detection of potential sliding surface, hydro-geological conditions of the slope up to a depth of 50 m and depth of the hard rock. The test has clearly outlined the utility of ERT & gravity methods in landslide investigations. More over these methods helped in understanding the active landslides processes and hazard assessment in detailed scale, characterised by low grade metamorphic rocks in a complex geological setting
