San Gregorio is situated at the base of a carbon- ate relief bounded by the Aterno river alluvial plain. The geological features of the area are very complex: jointed carbonate bedrock, cemented gravels and alluvial fan crop out in the village. Co-seismic ground fractures were seen along SW dip- ping active fault segments crossing San Gregorio. We integrated the microzona- tion studies with new geological, geotechnical and geophysical data for supporting the reconstruction planning of the village. Noise measurements show strong and polarized peaks in the horizontal-to-vertical spectral ratios (H/V) in the 3-7 Hz frequency band. Interestingly, the alluvial fan and the outcropping rock masses show both H/V peaks. To understand the influence of rock mass joint condition on site effect, we performed structural surveys on carbonate bedrock to look for a possible correlation between rock fracturing and ground-motion amplification195 26 - PublicationRestrictedActive normal faulting and large-scale mass wasting in urban areas: the San Gregorio village case study (L’Aquila, central Italy).

We dug two paleoseismological trenches across the fault to investigate its Late Quaternary ac- tivity and to verify whether the co-seismic ground ruptures could be effectively re- lated to the fault activation. The trenches showed that, in the past few millennia, the fault branch was responsible for surface displacement much larger than that determined by the 2009 earthquake. Moreover, geological/geomorphological field survey de-fined that the central portion of the structure is utilised in its shallowest portion as sliding plane of a large-scale gravitational mass movement. In particular, one of the paleoseismological trenches revealed that the large scale mass wasting is probably characterised by both continuous displacement and abrupt events of movement. Seismological investigations defined small amplification on rock site along the investigated fault, to be likely related to the joint and fracture condition deter-mined by the fault activity.264 21
