Regione Piemonte - Landslides - Geoportale Arpa Piemonte

he theme exposes the different types of landslide related to previous and current instability. Landslides related to the substrate are distinguished typologically according to the Varnes classification (1978). For each single type (with the exception of "collapses") there are associated information concerning the speed of movements during activations both for the preparatory phase and for the collapse phase. It also provides information on the state of evolution of the movements distinguishing the ancient or recent landslides characterized by more or less recurrent activations in the last 30 years, from those for the most ancient characterized by widespread quiescence. The different phenomena were systematically detected by means of a photointerpretation study associated with terrain surveys, often integrated and screened with historical archive information examined starting from 19th century documents. The dataset is part of the Database of Geological Processes carried out in the second half of the 80s by the Geological, Meteorological and Seismic Risk Prevention Sector of the Piedmont Region (later merged into the ARPA) to respond to the growing request for logical and structured information on the territory , necessary for the planning, coordination and direction of choices and interventions in the territorial-geological field
