The Mass Wasting of France ( Landslides can cause the loss of people, destruction of infrastructure , damage to land and loss of natural resources.) The largest landslide to occur in France was between 1877-88. It was known as the La Clapiere landslide located in the Southern Alps. T he total area of the landslide is approximately 1.2 km² and its volume is estimated at around 50 million cubic meters (50 hm 3 ). It was only around 1990-1991 that the upper and lower speeds converged, indicating the transition to an overall rotational slip. About 40 years ago, a boulder had fallen down to the road and there was an instability of a slope which lead up to the definitely on the right bank slope of the Tinee river. The slope is marked by the footprint of the Tinee glacier that occupied the valley; steep slope at the base (about 40°), slope failure around hill 1600 m and softer slope above. (Rockfalls occur ...
