GNGTS 2023 - Atti del 41° Convegno Nazionale

Session 1.1 GNGTS 2023 Calabrian Arc may hinder the result. In the event a fault plane is imaged in the deep subsurface, with an upper tip likely deeper than 3-4 km, it can be verified whether some sort of deformation connected to the fault is observed in the shallow seismic profiles so far acquired. In this case it would be possible to transfer the information to the grid of seismic profiles, thus characterizing the geometry of the fault and better understanding its evolution. Should new and successful geophysical acquisitions be made in the near future, the seismogenic fault plane could also become a possible target for an ICDP drilling aimed at intercepting and monitoring an active fault. Besides the scientific interest and the importance for hazard assessment, the understanding of the origin of the 1908 Messina Straits earthquake has also relevance for the project of a bridge crossing the strait, which always hovers. Here, we briefly review some of the proposed interpretations of the 1908 Messina fault, commenting on their reliability, and suggest that looking for a different approach would be advisable (Argnani and Pino, in press).
