Popis: Investigating active tectonics and the structural style of potentially-seismogenic structures at the outer front of active orogenic belts is particularly challenging when the frontal structures are buried and slowly deforming. This is the case of the blind fold-and-thrust belts surrounding the Padanian foreland of Northern Italy and developing across one of the most populated and industrialized Italian territories. In this paper, we focus on the seismogenic role of the Stradella thrust and its possible involvement in the activity of the buried Emilia arc, through a 3D geometric, kinematic, and seismotectonic reconstruction of the overall system. The integrated multi-scale analysis of structural and seismological data, inclusive of new focal mechanisms, highlights two seismological thrust volumes dipping at low-angle southwest-ward, at upper (
