New insight of geomorphology and landslide prone area detection using DEM

Three-dimensional histograms represented on density stereonets make it possible to analyze and identify the main structures of a rock slope. From such a representation, it is easy to detect the main features of a relief such as the main joints set shaping a slope, a fault scarp limiting an unstable rock mass, or a landslide scarp. Large-scale fault analysis helps the interpretation with respect to the location of some rockslides.
