Session 1.1 GNGTS 2023 Figure 1. Morpho-bathymetry of the Messina Strait region with superimposed the trace of the faults inferred by Meschis et al. (MTF) and Barreca et al (W-Fault). The Ionian Fault-Messina Strait Fault system (MSF) of Polonia et al. (2012) and the Ionian fault (IF) of Sgroi et al. (2021) are also shown; for this latter fault the greenish and purple fields represent areas subject to extension and compression, respectively. The area of strongest shaking produced by the 1908 earthquake is outlined by a dotted blue line. The black box is the surface projection of the model fault proposed by Boschi et al. (1989). The small yellow star indicates the epicentral location of Schick (1977). The white star locates the epicenter proposed by Michelini et al. (2005), and the white arrow indicates the rupture directivity (Pino et al., 2000). The thick white bars show the geodetic strain (Serpelloni et al., 2010). ME= Messina and RC= Reggio Calabria Bathymetric data have been obtained from EMODnet (2016) and topography is from Shuttle Radar Topography Mission (Farr et al., 2007). References Argnani, A.
