We present QUIN, a "QUaternary fault strain INdicators database", designed to integrate and unify published unpublished local-scale geological information derive parameters for structural seismotectonic analyses. It provides data on 3339 Fault Striation Pairs (FSP; plane slickenline), distributed within 455 survey sites. These are exposed along the intra-Apennine Quaternary extensional faults of Central Italy. The area covers an extent ~550 km in NW-SE direction. give FSP location, attitude...
Abstract QUIN database integrates and organizes structural-geological information from published unpublished sources to constrain deformation in seismotectonic studies. The initial release, QUIN1.0, comprised 3,339 Fault Striation Pairs, mapped on 445 sites exposed along the Quaternary faults of central Italy. present Data Descriptor introduces 2.0 which includes 4,297 Pairs 738 Structural Sites southern newly investigated span ~500 km Apennines chain, with strikes transitioning ~SE ~SW...
Abstract This study provides insights into the tectonic evolution of normal Mt Morrone Fault System (MMFS) in Central Italy and highlights utility multidisciplinary approaches reconstructing seismic history dormant fault systems. The MMFS comprises two parallel faults that traverse western slope Mt. Morrone, although system can produce M > 6 earthquakes, it has been aseismic post Roman times. Here, we combine geochemical analysis carbonate fault‐scarp samples with new structural data...
Abstract Following observations made in a survey campaign along the Lost River Fault (Idaho, USA) 2019, we integrate both original and previously published data to obtain detailed segmentation of fault sections that failed 1983 Borah Peak earthquake (Mw 6.9). The ruptured topographic surface with an oblique-normal faulting mechanism, activating two SW-dipping segments (Thousand Springs Warm Springs) branching SSW-dipping (Arentson Gulch Fault) producing coseismic ruptures up 3 m vertical...
Abstract 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, M w 7.1) and hosting largest European oil field on-land. Fieldwork-based observations Campania-Lucania area highlight SSW-dipping ~ 65 km-long normal-oblique-segmented fault, showing evidence recent activity possibly responsible 1857 earthquake. It crosses Maddalena ridge, linking...
Abstract The systematic study of faults that have released strong earthquakes in the past is a challenge for seismic hazard assessment. In carbonate landscapes, use rare earth element (REE) concentrations on slickensides may aid reconstruction fault slip history. We applied this methodology to Caggiano normal (Southern Apennines, Italy), cropping out southeast Irpinia 1980 CE earthquake (Mw 6.9), which was responsible both 1561 and partly 1857 Basilicata 6.7 7.1). integrated REE analysis...
The Crati Basin, located in Northern Calabria (Southern Italy), is a tectonically active region with complex fault systems and notable seismic activity (Brozzetti et al., 2017a; 2017b; Cirillo 2022; Lavecchia 2024). Understanding the tectonic dynamics of this area essential for evaluating current hazards. This study presents comprehensive 3D modelling approach that integrates geological field observations, topographic analysis, interpretation high-resolution reflection profiles, geodetic...
This contribution explores the approach and results of crustal stress strain rate comparisons across various geological contexts. Since early 1980s, researchers have investigated broad applicability these in regions with high, intermediate low deformation rates. The primary data sources for studies include focal mechanisms velocity fields from GNSS stations, although additional datasets, such as structural data, are also utilized. field is obtained through formal inversion, while derived...
In tectonically active areas, such as the Italian peninsula, studying faults responsible for strong earthquakes is often challenging, especially when occurred in historical times. cases, geoscientists need to integrate all available information from reports, surface geology, and geophysics constrain a seismotectonic point of view. this paper, we update review, according EMS-98 scale, macroseismic fields five main events 1783 Calabria sequence (5, 6, 7 February, 1 28 March, Mw 5.9 7.1), two...
The Himalaya–Tibet region represents a complex of active deformation related to the ongoing India–Eurasia convergence process. To provide additional constraints on processes shaping this region, we used comprehensive dataset GNSS and focal mechanisms data derived crustal strain stress fields. results allow detection features such as arc-parallel extension along Himalayan Arc coexistence strike-slip normal faulting across Tibet. We discuss our findings concerning relevant geodynamic models...
