The present work deals on an example of large landslide at Marina di Altidona, along the central Italy Adriatic coast, representative of many situations observed along the sea-cliff areas of the Marche and the Abruzzo regions; all these phenomena are located in areas which correspond to the most uplifted sectors during the Quaternary. The data collected, allow to hypothesize a past activation of a huge mass movement along a deep sliding surface, presently submarine. It was related to the high relief connected to the strong tectonic uplift of the middle-upper Pleistocene, to which a probable high seismicity was also associated. The validation of the geomorphological model has been carried out by applying a Finite Difference Numerical Code (FLAC_2D) to a huge gravitational movement and, in particular, by characterizing the dynamic evolution along significant transects.

Abstract
The present work deals on an example of large landslide at Marina di Altidona, along the central Italy Adriatic coast, representative of many situations observed along the sea-cliff areas of the Marche and the Abruzzo regions; all these phenomena are located in areas which correspond to the most uplifted sectors during the Quaternary. The data collected, allow to hypothesize a past activation of a huge mass movement along a deep sliding surface, presently submarine. It was related to the high relief connected to the strong tectonic uplift of the middle-upper Pleistocene, to which a probable high seismicity was also associated. The validation of the geomorphological model has been carried out by applying a Finite Difference Numerical Code (FLAC_2D) to a huge gravitational movement and, in particular, by characterizing the dynamic evolution along significant transects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
