Landslides and climatic conditions in the Barcelonnette and Vars basins (Southern French Alps, France)

Research into the climatic causes behind the triggering and reactivation of landslides has been carried out in two basins in the Southern French Alps, where a great many landslides have occurred over more than a century. Correlations between landslides and climate are sometimes precise and closely related in time, at other times imprecise and more distant. The better known the type of landslide and the date of its occurrence, the greater the correlation may appear. Be this as it may, climate is never the sole cause. This paper deals with the limits of the effects of climate.
