Rockfalls are among the most dangerous natural hazards. The study of these phenomena may be complex in relation to the geology and the rock mass characteristics. Recent advances on the use of remote sensing techniques made the survey of rock slopes easier and faster, increasing the amount and quality of data. At the same time, the improved availability of software for analyzing rock slopes and simulating rockfalls permit a more detailed and precise definition of rockfall hazard areas.In this context, this research highlights the importance of using remote sensing techniques in the study of these phenomena and, in particular, in the development of accurate ad reliable geological and structural models.The study areas have been investigated through conventional geological/structural surveys, UAV photogrammetry and iPad based LiDAR. A new approach for defining different geological/structural domains will be showed based on geological data and airborne LiDAR extracted Slope Units. The data gathered from surveys have been used to perform rockfall simulations and point out the importance of model validation and input parameters. Finally, new innovative visualization techniques based on the use of Virtual/Augmented Reality will be introduced for an improved interpretation of geological and structural data and simulation results.
