We reconstructed the 3D geometries and kinematics of the interconnected fault pattern responsible for the moderate-magnitude earthquakes, which were recently affected by the 2010-2014 seismic activity of the Pollino area (Calabrian-Lucanian boundary). The 3D Faults Model of the Pollino area was reconstructed by integrating the structural-geological...

We studied some exposures of the Roccacaramanico Conglomerate (RCC), a calcareous-clastic mega-bed intercalated within the Late Messinian–Early Pliocene pelitic succession of the La Queglia and Maiella tectonic units (central Apennines). The outcrops, localized in the overturned limb of a kilometric-scale syncline, show a complex array of fractures...

Studying faults capable of releasing moderate-to-strong earthquakes is fundamental for seismic hazard studies, especially in a territory that was subject to the strongest peninsular Italy earthquake (1857, Mw 7.1) and hosting the largest European oil field on-land. Fieldwork-based observations in the Campania-Lucania area highlight a SSW-dipping ~...

Following observations made in a survey campaign along the Lost River Fault (Idaho, USA) in 2019, we integrate both original and previously published data to obtain a detailed segmentation of the fault sections that failed in the 1983 Borah Peak earthquake (Mw 6.9). The earthquake ruptured the topographic surface with an oblique-normal faulting mec...

We reconstruct the 3D fault model of the structures causative of the 2010-2014 Pollino seismic activity by integrating structural-geological and high-resolution seismological data. We constrained the model at the surface with fault-slip data, and at depth, by using the distributions of selected high-quality relocated hypocenters. Relocations were p...

Active compressional tectonics along the outer front of the Apenninic-Maghrebian chain (Italy) is well documented along the northern and central segments and in Sicily. On the other hand, the Southern Apenninic Outer Front (SAOF) orogenic activity is well established only until the Lower-Middle Pleistocene. We address the hypothesis of its subseque...
Code
FAULT-STRIATION PAIR ANALYSIS (F-SPA) is an easy-to-use tool for the processing and graphics of geological data to perform kinematic analyzes of Fault-Striation Pair (FSP) from geological field data and focal mechanisms. We developed an algorithm in MATLAB environment (www.mathworks.com) to make several calculations from fault planes and striation...

The “Q-host faults database” is an original compilation, on a GIS platform, of Quaternary faults hosting the Structural Sites (SS) of the QUIN 1.0 database (Lavecchia et al., 2022 - Scientific Data)
Preprint
Full-text available
The integration of field geology and high-resolution seismological data allowed us to reconstruct the 3D Fault Model of the sources which gave rise to the 2010–2014 Pollino seismic sequence. The model is constrained at the surface by structural geological data which provide the true attitude of the single faults and their cross-cut relationships. A...

The Apenninic chain, in central Italy, has been recently struck by the Norcia 2016 seismic sequence. Three mainshocks, in 2016, occurred on August 24 (MW6.0), October 26 (MW 5.9) and October 30 (MW6.5) along well-known late Quaternary active WSW-dipping normal faults. Coseismic fractures and hypocentral seismicity distribution are mostly associated...

The 2016 Central Italy seismic sequence was characterized by two main events: 24 August, Mw 6, and 30 October, Mw 6.5. We carried out high-resolution field sampling and DInSAR analysis of the coseismic and intra-sequence ground deformations along the Mt Vettore-Mt Bove causative fault (VBF). We found that during the intra-sequence period (24 August...
Article
In the upper Tertiary succession of the Maiella Tectonic Unit (Abruzzo, Italy), coarse calciclastic layers, hereinafter referred to as Roccacaramanico Conglomerate (RCC), were deposited during a short time span which approximates the Miocene-Pliocene boundary. The biostratigraphic characterization of RCC is well constrained by previous studies of f...

The ~ 900 km long Apennine fold-and-thrust belt dominates mainland-Italy and Sicily, where it connects with the Maghrebian chain. The belt reached its present setting following a progressive foreland-ward propagation, started about 10 Ma and continued through the Quaternary. The Apennine Outer Front is still active along its northern and central se...

Earthquakes are a major natural hazard for the Mediterranean area. Italy is one of the countries where they are among the deadliest disasters. Earthquakes occurred in the last fifteen years in central-southern Italy (S. Giuliano di Puglia 2002 Mw 5.4, l’Aquila 2009 Mw 6.3, Norcia 2016 Mw 6.5) confirm the significant vulnerability of buildings, even...

We focus on the coseismic surface faulting exposed along the Mt. Vettore-Mt. Bove fault system (VBF, central Italy), that activated during the 24 August 2016, Amatrice earthquake (Mw 6.0) and soon after reactivated during the 26 October Visso (Mw 5.9) and 30 October Norcia events (Mw 6.5 mainshock). We systematically recognized the coseismic surfac...

We provide a database of the coseismic geological surface effects following the Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one of the strongest seismic events to occur in Europe in the past thirty years, causing complex surface ruptures over an area of >400 km2. The database originated from the collaboration of sev...

In this work, we suggest that two ~ N-S striking, east-dipping LANFs, outcropping over distance of nearly 90 km, have been driven the Pleistocene to present extension of the Calabro-Lucania boundary and of the northern Calabrian Arc. Through detailed geological mapping, integrated with structural analysis and, locally, with interpretation of seismi...
Article
New geological field data, integrated with commercial seismic lines, allowed us to constrain the geometry and time-space evolution of the fault system that ruled the tectono-sedimentary evolution of the NS-striking Crati graben, in the axial portion of the northern Calabrian Arc. We highlight that this basin is controlled by a 60-km long east-dippi...

On 24 August 2016 (01:36 UTC) the intra-Apennine extensional fault system of Central Italy released a ML 6.0 destructive earthquake between the towns of Norcia and Amatrice. The main shock produced widespread damages and fatalities, devastating several localities and killing about 300 people. The main event was followed by a significant aftershock...

We use a multidisciplinary approach to gather preliminary evidence for a Quaternary east-dipping extensional detachment in Central Italy. This structure crops out in the Sabini-Eastern Simbruini (SES) and would be hidden at mid-crustal depths beneath the L'Aquila 2009 (Mw6.3) epicentral area. The SES geometry is reconstructed through geological map...

We investigate the ground deformation and source geometry of the 2016 Amatrice earthquake (Central Italy) by exploiting ALOS2 and Sentinel-1 co-seismic DInSAR measurements. They reveal two NNW-SSE striking surface deformation lobes, which could be the effect of two distinct faults or the rupture propagation of a single fault. We examine both cases...

The following is a geological study of a Quaternary and active normal fault-system, which crops out in the Pollino area, a seismogenic sector of the Southern Apennines, Italy. From 2010 to 2014, this area was affected by long lasting seismic activity characterized by three major events which occurred in May 2012 (Mw 4.3), in October 2012 (Mw 5.2) a...

The Sulmona plain (central Italy) is an intramontane basin of the Abruzzi Apennines that is known in the literature for its high seismic hazard. We use extensive measurements of ambient noise to map the fundamental frequency and to detect the presence of geological heterogeneities in the basin. We perform noise measurements along two basin-scale or...

We investigated the normal fault system outcropping along the northern slope of the Matese Mts. (Molise). This sector, belonging to the Bojano basin, experienced an extensional tectonics starting from the Middle Pleistocene (Di Bucci et al., 2005; Amato et al., 2014). The seismogenic features of the fault system (N-MFS in Galli and Galadini, 2003)...
