With its mountains, hills and fragile cliffs, Italy is one of the European countries most susceptible to hydrogeological disasters: landslides, sinkholes, erosion and floods. The situation is causing concern for the country’s local authorities. Over 500,000 buildings are situated in areas exposed to landslides, and nearly 38,000 churches, monuments, historic and cultural heritage sites are at risk.
