Landslide Hazard Assessment in a Monoclinal Setting (Central Italy): Numerical vs. Geomorphological Approach

A correct landslide hazard assessment (LHA) is fundamental for any purpose of territorial planning. In Italy, the methods currently in use to achieve this objective alternate between those based on mainly qualitative (geomorphological) and quantitative (statistical–numerical) approaches. The present study contributes evaluation best procedure be implemented LHA, comparing results obtained using two different approaches (geomorphological numerical) a context characterized by conditioning triggering factors, favorable instability slopes. obtained, although preliminary, evidence respective limitations demonstrate how combined approach can certainly provide mutual advantages, addressing choice numerical model through direct observations surveys.
