Session 1.1 GNGTS 2024 Figure 1: a) Map of seismogenic source types in southern Calabria and major historical earthquakes; The red dashed line represents the coseismic evidence of the 5 February seismic event. b) Front of the Appenninic–Maghrebian Orogen (red line) in the context of the Europe–Africa plate convergence. c) Simplifed structural map of the Calabrian Arc domain; d) Upper Pleistocene deposits, tlted by the main fault actvity. The main fault (red line) juxtaposes the Pleistocene sediments with the basement rocks. e) Slickenlines on the main fault plane (F1). Previous seismic source models for the 1783 seismic sequence The 1783 seismic sequence was characterized by the fve events which the main occurred on February 5 that destroyed towns and villages located at the western foot of the northern Aspromonte (i.e., S. Cristna D’Aspromonte and S. Giorgio Morgeto). According to de Dolomieu (1784), afer the 5 February mainshock, a 20-km-long scarplet that developed at the western foot of the Aspromonte Mountain between the village of S. Cristna and S.
