The Strait of Messina: Seismotectonics and the source of the 1908 earthquake
Earth-Science Reviews, Volume 218, 2021, 103685, ISSN 0012-8252, https://doi.org/10.1016/j.earscirev.2021.103685. (https://www.sciencedirect.com/science/article/pii/S0012825221001860)
Highlights
• High-resolution marine seismic data provide evidence for surface faulting in the Messina Strait.
• An active, previously unmapped 34.5 km-long extensional fault has deformed the seafloor.
• A low-angle, foreland-dipping discontinuity is evidenced by 3D-positioning of earthquakes.
• Stress perturbation on the deeper discontinuity is accounted to transfer additional stress on the overlying brittle faults.
• Results allow us questioning most of the previous models concerning the 1908 seismogenic source.
