Short summary
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.

Short summary
Short summary
The Outer Thrust System (OTS) in coastal Abruzzi (Italy) remains debated in terms of its geometry, seismic activity, and deformation style. This study presents a new seismic tomography of the Abruzzi Arc basal thrust, revealing mid-crustal doubling at depths of 14–24 km. The conceptual 3D model highlights deep compressive tectonics influencing the crustal structure. If the thrust is seismogenic, it could have significant implications for regional geodynamics and seismic hazard assessment.

Short summary
We propose a methodology useful to evaluate (1) the reliability of a focal mechanism solution inferred by the inversion of seismological data and (2) the performance of a seismic network, operated to monitor natural or induced seismicity, to assess focal mechanism solutions. As a test case, we studied the focal mechanism reliability by using synthetic data computed for ISNet, a local seismic network monitoring the Irpinia fault system (southern Italy).

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.
