Description:
A multidisciplinary methodology, integrating stratigraphic, geomorphological and structural data, combined
with GIS-aided analysis and PS-InSAR interferometric data,was applied to characterize the relationships between
ground deformations and the stratigraphic and themorphostructural setting of the Venafro intermontane basin.
This basin is a morphostructural depression related to NW-SE and NE-SW oriented high angle normal faults bordering
and crossing it. In particular, a well-known active fault crossing the plain is the Aquae Juliae Fault, whose
recent activity is evidenced by archeoseismological data. The approach applied here reveals newevidence of possible
faulting, acting during the Lower to Upper Pleistocene, which has driven the morphotectonic and the environmental
evolution of the basin. In particular, the tectonic setting emerging from this study highlights the
influence of theNW-SE oriented extensional phase during the late Lower Pleistocene – earlyMiddle Pleistocene,
in the generation of NE-SWtrending, SE dipping, high-angle faults andNW-SE trending, high-angle transtensive
faults. This phase has been followed by a NE-SW extensional one, responsible for the formation of NW-SE
trending, both NWand SE dipping, high-angle normal faults, and the reactivation of the oldest NE-SWoriented
structures. These NW-SE trending normal faults include the Aquae Juliae Fault and a new one, unknown until
now, crossing the plain between the Venafro village and the Colle Cupone Mt. (hereinafter named the
Venafro-Colle Cupone Fault, VCCF). This fault has controlled deposition of the youngest sedimentary units (late
Middle Pleistocene to late Upper Pleistocene) suggesting its recent activity and it is well constrained by PSInSAR
data, as testified by the increase of the subsidence rate in the hanging wall block.
