N2  - The paper describes a method for the evaluation of slope instability for urban planning purposes, applied in the test area 'Oltre Po Pavese' (Regione Lombardia, Italy). A statistic and a probabilistic approach have been applied for the estimation of landslide activations and for the definition of potentially unstable areas. The displacement has been obtained through a simplified dynamic analysis, using deterministic methods: first the critical horizontal acceleration coefficient (K-c) has been evaluated, second the displacement has been calculated using the K-c values and the seismic input values, such as peak ground acceleration (PGA) and Arias intensity (Ia), through empirical relationships between displacement and Ia values for different K-c values. The results can be used by the regional government to give to the municipalities of the area a guide for the selection of the zones to be studied with future and more detailed analyses.     <p>Language: en</p>
