It is widely recognized that tectonic activities affect the mode of landslide formation and the evolution of slopes. But little is known on how tectonic structures control the geometry, kinematics and temporal aspects of deep-seated landslides. The aim of this research is to study the way slope failures are formed in tectonically active regions. To do so, major axes of seismic fields created from landslide distributions will be correlated with the direction of faults. This would allow distinguishing landslides formed with and without the contribution of tectonic forces. To map landslides and tectonic structures, a combination of aerial photograph and satellite image interpretations followed in the middle by detailed, extensive field surveys, will be used. Stereoscopic views of aerial photographs and satellite image interpretations often provide evidence of past geomorphologic processes, and can allow delineating faults, fractures and landslide scarps.
