Description:
The Piano di Pezza fault (PPF) is the north-westernmost segment of the 〉20 km long Ovindoli-Pezza active normal
fault-system (central Italy). Although existing paleoseismic data document high vertical Holocene slip rates (~1 mm/yr) and a
remarkable seismogenic potential of this fault, its subsurface setting and Pleistocene cumulative displacement are still unknown.
We investigated the shallow subsurface of a key section of the PPF using seismic and electrical resistivity tomography coupled
with time-domain electromagnetic measurements (TDEM). We provide 2-D Vp and resistivity images showing details of the fault
structure and the geometry of the shallow basin infill down to 35-40 m depth. We can estimate the dip and the Holocene vertical
displacement of the master fault. TDEM measurements in the fault hangingwall indicate that the pre-Quaternary carbonate
basement may be found at ~90-100 m depth.
