Identification of Hydro-Meteorological Triggers for Villerville Coastal Landslide

The Villerville–Cricqueboeuf landslide (Normandy, France) is an example of a very well monitored coastal landslide. The long time series goes back to the 1980s initiated after the January 1982 major re-activation of the landslide complex. The combination of translational movement of large blocks of chalk and sandstone and the rotational movement at the cliff's toe results in a very complex hydrological system. Earlier research showed a qualitative connection of displacement or re-activation with meteorological forcing and inland hydrological circumstances.
