The research group was involved in the NASA4SHA PRIN2020 Project (Fault segmentation and seismotectonics of active thrust systems: the Northern Apennines and Southern Alps laboratories for new Seismic Hazard Assessments in northern Italy), which aims to explore the complexity of faults in active thrust systems in the Northern Apennines and Southern Alps of Italy. The study area, located within the external Pliocene-Quaternary front of the Eastern Southalpine Chain (Friuli, NE Italy), is characterized by distinct WSW-ENE trending and S-verging reverse fault planes, arranged in thrust systems that affect the Quaternary succession. The Deep and Shallow Electrical Resistivity Tomography were integrated to define a multiscale geophysical approach on the Budoia-Aviano thrust system, which is part of the Polcenigo–Montereale fault system. Adopting a multilayer approach, the integration of geological and morphotectonic field surveys with geophysical investigations and paleoseismological analyses enabled the detection of the Budoia-Aviano backthrust, revealing the first evidence of its activation during the Late Pleistocene to Holocene.
