dc.description.abstractIn this paper we investigate the border between the Sannio and Irpinia seismogenic regions, a sector of the southern Apennine chain considered among the most active seismic areas of the Italian peninsula, to shed further light on its complex seismotectonic setting. We integrated recent seismicity with literature data. A detailedanalysis of the seismicity that occurred in the 2013–2016 time interval was performed. The events were re-located, after manual re-picking, using different approaches. To retrieve information about the stress field activein the area, inversion of Fault Plane Solutions was also carried out. Hypocentral distribution of the relocated events (ML≤3.5), whose depth is included between 5 and 25 km with the deepest ones located in the NW sector of the study area, shows a different pattern between the northern sector and the southern one. The computed Fault Plane Solutions can be grouped in three depth ranges: < 12 km, dominated by normal dip-slip kinematics;12–18 km, characterized by normal dip-slip and strike-slip kinematics; > 18 km, dominated by strike-slip ki-nematics. Stress field inversion across the whole area shows that we are dealing with an heterogeneous set ofdata, apparently governed by distinct stressfields. We built an upper crustal model profile through integration of geological data, well logs and seismic tomographic pro files. Our results suggest the co-existence of different tectonic styles at distinct crustal depths: the upper crust seems to be affected mostly by normal faulting, whereas strike-slip faulting prevails in the intermediate and lower crust. We infer about the existence of a transitional volume, located between 12 and 18 km depth, between the Sannio and Irpinia regions, acting as a vertical transfer zone.en
