Preliminary assessment of the effects of climate change on landslide activity of Orvieto clayey slope

The first results of a procedure developed for the evaluation of the effects of climate change on landslide phenomena are shown. The case history is represented by the northern slope of the Orvieto Hill (Central Italy) affected by slow translational movements directly related to soil-atmosphere interaction. The results concern the analysis of available weather observations and a preliminary assessment of the effects of climate changes on landslide activity; the limits of the adopted simplified approaches are identified and the further developments aimed at improving the prediction are so indicated.
