Abstract

The most likely landslide failure surface geometry can be estimated using simple rules using splines, tangent of failure surface and sloping local base level (SLBL). Using these assumptions it is possible to get the probability to reach a failure surface vertically by inferring the lower limits of the potential failure surface. The potentialities of the method are shown using the example of the landslide La Frasse (Switzerland).
