Short summary
Short summary
This study presents a new geological model of the Fano-Pesaro offshore area, refining its tectonic framework. We identified multiple fault detachments at different depths, influencing thrust system dynamics and deformation. This work highlights the importance of integrating seismic and borehole data, even legacy, to build reliable subsurface models. These findings contribute to improved seismic hazard assessment and support offshore energy development and carbon storage projects.

Short summary
Short summary
The Pollino region is a highly seismic area of Italy. Increasing the geological knowledge on areas like this contributes to reducing risk and saving lives. We reconstruct the 3D model of the faults which generated the 2010–2014 seismicity integrating geological and seismological data. Appropriate relationships based on the dimensions of the activated faults suggest that they did not fully discharge their seismic potential and could release further significant earthquakes in the near future.

Short summary
Past strong earthquakes can produce topographic deformations, often
memorizedin Quaternary sediments, which are typically studied by paleoseismologists through trenching. Using a ground-penetrating radar (GPR), we unveiled possible buried Quaternary faulting in the Mt. Pollino seismic gap region (southern Italy). We aim to contribute to seismic hazard assessment of an area potentially prone to destructive events as well as promote our workflow in similar contexts around the world.
