Abstract
The field trip focuses on the Quaternary tectonic structure of the Campanian-Lucanian Apennines. This area is responsible for some of the most destructive southern Apennine earthquakes, which were studied within the context of a PRIN-2017 project referred to as MUSE-4D, that stays for "Overtime tectonic, dynamic and rheologic control on destructive multiple seismic events - Special Italian Faults & Earthquakes: from real 4D cases to models". Part of the project focuses on two M7-class multi-event Special EarthQuakes (SEQs): Irpinia 1980 and Basilicata 1857, which released similar cumulate magnitudes in time lapses variable from few seconds (1980) to few minutes (1857). These events and their host structures were analysed in innovative overtime (Quaternary and active) and multi-scale (local to regional) approaches within the project context. The geometry, kinematics, and structural style of the potentially seismogenic sources of these events are still questioned in the literature. A full constraint of their surface setting is fundamental to reducing the number of variables in assessing the extensional tectonics of the area and in the 3D fault model building. The three-days field trip is finalized to visit both the largely agreed and the controversial fault exposures to discuss them among the geo-scientific community.
