Coastal movements are minimal and do not impact the stability of the Bridge.
The Strait of Messina is a stretch of sea approximately 33 kilometers long, with a width varying from about 3.1 kilometers at its narrowest point to a maximum of 16 kilometers.
The Sicilian and Calabrian coasts experience a slow and slight process of mutual receding and uplifting, a phenomenon that has been extensively analyzed and deemed irrelevant for the purpose of this project. Studies conducted by the Department of Earth Sciences at La Sapienza University of Rome and the National Institute of Geophysics and Volcanology (INGV), utilizing data from the Global Navigation Satellite Systems (GNSS) of the RING-INGV network (National Integrated GPS Network, which continuously monitors ground deformation), show that the relative movement between the two sites selected for the Bridge pylons (Calabria and Sicily) is less than 1 millimeter per year. This movement is technically negligible and does not affect the stability of the infrastructure.
