The Strait of Messina area represents a scientific challenge of great importance for geophysics, geochemistry and, in general, for earth sciences, due to the close coexistence of different geodynamic regimes. Here are present tectonic systems able to generate energetic earthquakes, among the strongest of the entire Italian seismic catalogue and some of the most important active volcanoes. It is mandatory to consider it a natural laboratory in which to invest in research and monitoring infrastructures [Mattia et al., 2008; 2009]. It is also for this reason that the INGV has decided to set up a site in Messina where the data of a dense network of instruments and technical and research personnel can converge. The piezometric network, in particular, is a challenge within a challenge, since...
