“…The Fucino Basin itself has been infilled by >1,000 m of Pliocene-Recent continental clastic succession, mostly buried below the present-day topographic surface (Patacca et al 2008). None of the wells drilled to date reached depths greater than 200 m (Boncio et al, 2016;Cavinato et al, 2002;Di Naccio et al, 2020;Giaccio et al, 2017 -Figure 3) and sonic or checkshot data were not collected and are unavailable at these shallow and deeper depths. Some of the Pliocene-Pleistocene Fucino units, however, are thought to have been uplifted and exposed in terraces, particularly towards the northern and north-eastern periphery of the Fucino Basin (Figures 2b and 4; Messina, 1996).…”

“…The Upper Pleistocene to Holocene ‘Fucino Unit’, comprises basin‐centric lacustrine and basin‐marginal alluvial and fluvio‐deltaic facies. This is the only formation penetrated by wellbores (Boncio et al, 2006; Di Naccio et al, 2020; Cavinato et al., 2002), some of which were dated by tephrochronology (Giaccio et al., 2015, 2017).

Normal faults grow either by radial propagation and segment linkage or by accruing displacement without a proportional increase in fault length. To test these competing models of fault growth, a novel 2D seismic stratigraphic interpretation of the recentFucino Basin of the central Apennines (Italy) has been performed. The Fucino is a major Pliocene-Quaternary non-marine 'extensional collapse basins', developed immediately after the Apenninic compressional strain had locally abated, and bounded by seismogenic faults that generate strong (Mw = 6-7) and destructive earthquakes.The Fucino is an overall dual polarity half-graben, built around two border fault systems: the northern one lies along the east-northeast striking Avezzano-Bussi regional fault-zone; the other, south-eastern trending, bounds the basin to the east. Two separate fault-driven depocentres of fluvio-lacustrine sequences (maximum thicknesses of ~1,750 m) are present. One is associated to the northern border faults, with mainly Late Pliocene activity; the second is to the hanging-wall of the eastern border-faults and reveals a stepwise Pleistocene-Recent activity. Tectonic depocentres have migrated clockwise through time, and new-born fault systems have developed at the south-eastern basin periphery (Gioia dei Marsi area). This, together with the progressive accumulation of throw in time without significant fault lengthening, suggests that the model of fault growth by segment linkage is not the best explanation for this basin. Instead, the stepwise onset and growth of the Fucino extensional collapse faulting, and its ongoing earthquake hazard, may have been promoted by polyphase inversion tectonics of inherited deep-seated zones of weaknesses (e.g. Avezzano-Bussi Line).

“…Thus, near this basement dislocation, the amplitude and shape of the misfit may be an indicator of a model still too smooth. Florio [8] analyzed the gravity anomalies of a synthetic basement model (the "Bishop" model [54]) created to verify the performances of processing and modeling techniques of potential fields. This model contains numerous fault scarps with varying throws and orientations, analogous to basement fault structures within major sedimentary basins.…”

“…Several authors analyzed geological surface data, borehole stratigraphy, and seismic data [2,5,6], correlating sedimentary and seismic facies and providing estimates for the depth to the base of the Plio-Pleistocene sediments. Several uncertainties still exist, however, concerning the location of faults and their extent, the variation of seismic velocities with depth, the geological interpretation of reflective surfaces, and the overall reliability of the 2D/3D models [6][7][8][9][10].…”

Basement Mapping of the Fucino Basin in Central Italy by ITRESC Modeling of Gravity Data

Sediments infilling in intermontane basins in areas with high seismic activity can strongly affect ground-shaking phenomena at the surface. Estimates of thickness and density distribution within these basin infills are crucial for ground motion amplification analysis, especially where demographic growth in human settlements has implied increasing seismic risk. We employed a 3D gravity modeling technique (ITerative RESCaling—ITRESC) to investigate the Fucino Basin (Apennines, central Italy), a half-graben basin in which intense seismic activity has recently occurred. For the first time in this region, a 3D model of the Meso-Cenozoic carbonate basement morphology was retrieved through the inversion of gravity data. Taking advantage of the ITRESC technique, (1) we were able to (1) perform an integration of geophysical and geological data constraints and (2) determine a density contrast function through a data-driven process. Thus, we avoided assuming a priori information. Finally, we provided a model that honored the gravity anomalies field by integrating many different kinds of depth constraints. Our results confirmed evidence from previous studies concerning the overall shape of the basin; however, we also highlighted several local discrepancies, such as: (a) the position of several fault lines, (b) the position of the main depocenter, and (c) the isopach map. We also pointed out the existence of a new, unknown fault, and of new features concerning known faults. All of these elements provided useful contributions to the study of the tectono-sedimentary evolution of the basin, as well as key information for assessing the local site-response effects, in terms of seismic hazards.

Combining earth sciences with archaeology to investigate natural risks related to the cultural heritage of the Marsica region (central Apennines, Italy)

Methods of Earth Sciences have been employed in archaeological sites of the Marsica region, central Italy, in two different perspectives: to enhance knowledge on past natural events which damaged/destroyed ancient settlements/monuments and to gather data useful/necessary for preservation of the local cultural heritage. Within this wide perspective, the paper deals with (i) recent archaeoseismological investigations at Alba Fucens and other sites of the Fucino Plain which add evidence of sudden building collapse to the already available (archaeoseismological and paleoseismological) data concerning seismicity of fifth-sixth century AD; (ii) archaeological investigations on remains of the Medieval church of San Bartolomeo showing that coseismic damage in 1349 caused the abandonment of part of the building and its (re)use for burials; (iii) evidence of slope instability which caused rapid mass deposition in the lowest sector of ancient Alba Fucens since around the half of the sixth century AD, inhibiting the occupation of the Roman town; (iv) capable faulting potentially affecting the westernmost sector of the huge hydraulic works made by Romans during the first-second century AD to drain former Lake Fucino.
