Summary:
The use of geophysical methods to study landslides may provide useful information on defining internal structure of a landslide, identifying geometry of sliding surface, determination of groundwater effect on landslide, physical properties of landslide material and landslide mass movement. In this study, electrical resistivity tomography and seismic refraction tomography methods were used as complement to geotechnical and monitoring tests. The results from each geophysical study were very evident for clarifying the internal structure of the landslide, the physical properties of the rock mass involved and defining the sliding surface geometry.
