Seismotectonic framework. (A) Circum-Mediterranean crustal thrust earthquakes (World Stress Map database, Heidbach et al., 2018). (B) Seismotectonic provinces and focal mechanisms 1971–2022, depth <40 km (updated after Lavecchia et al., 2021). (C) Hypocentral sections with focal mechanisms and interpolated fault traces (dashed red lines), after de Nardis et al. (2022; projection semi width = 20 km, traces in Fig. 1B). (D) 3-D fault model of T1 and T2 megathrusts from de Nardis et al. (2022).
