The main task is to assess the role of this influence in determining natural geological hazards such as eruptions, landslides and earthquakes. The geologic-tectonic control of the substrate on the volcanoes has been usually considered questionable or less important than the conditions of the deep magma source, whereas the control of volcanoes on their basement has even received very little attention. This project improves the comprehension of these phenomena by a strong interdisciplinary approach that ties data on the various geological conditions and heritages of the basement with the deformation processes and geological evolution of different volcanic edifices. We compiled stratigraphic, structural, geomorphological, geophysical, geotechnical, petrographic, geochemical and geochronological data. These data have been transferred to the laboratory-working groups, thus providing realistic numerical and physical simulation even of complex geological structures. Here we present a selection of the main results obtained for some of the studied key volcanoes.
