The Po Plain is a low-relief area characterised by active shortening accommodated blind thrust faulting. In this almost flat region depositional rates are similar to tectonic and deformation seldom expressed noticeable surface anticlines. We adopted geomorphological approach based on the detailed analysis of drainage network identify location faults. A total 36 anomalies represented sudden river diversions shifts in channel pattern were accurately mapped. After comparison with subsurface...
We provide a database of the coseismic geological surface effects following Mw 6.5 Norcia earthquake that hit central Italy on 30 October 2016. This was one strongest seismic events to occur in Europe past thirty years, causing complex ruptures over an area >400 km2. The originated from collaboration several European teams (Open EMERGEO Working Group; about 130 researchers) coordinated by Istituto Nazionale di Geofisica e Vulcanologia. observations were collected performing detailed field...
For decades, alluvial plains have been the areas of fastest population growth over most globe. Modern societies demand growing extensions flat and easily accessible land to accommodate swelling urban areas, booming industrial districts, large power plants, multi-runway airports. But how can we tell if such hide active faults? How assign a significant pre-instrumental earthquake its causative source? In other words, modern deal with buried, that is say, 'invisible' faults, elusiveness hazards...
<p>Since the beginning of ongoing Amatrice seismic sequence on August 24, 2016, initiated by a Mw 6.0 normal faulting earthquake, EMERGEO Working Group (an INGV team devoted to earthquake aftermath geological survey) set off investigate any coseismic effects natural environment. Up now, we surveyed about 750 km2 and collected more than 3200 observations as differently oriented tectonic fractures together with intermediate- small- sized landslides, that were mapped in whole area. The...
Abstract The prompt identification of faults responsible for moderate‐to‐large earthquakes is fundamental understanding the likelihood further, potentially damaging events. This increasingly challenging when activated fault an offshore buried thrust, where neither coseismic surface ruptures nor GPS/InSAR deformation data are available after earthquake. We show that on 9 November 2022, Mw 5.5 earthquake Pesaro ruptured a portion Northern Apennines thrust front (the Cornelia system [CTS]). By...
Abstract This study explores the seismotectonics of Kachchh in western India, a region with low-to-moderate strain rate and history significant earthquakes, notably 1819, Mw 7.8 Allah Bund, 2001, 7.6 Bhuj. Despite its substantial seismic risk, comprehensive studies on Kachchh’s seismogenic sources are scarce. is attributed to concealed nature active structures, hindering definitive age constraints paleoseismological research. Our research comprises detailed paleoseismic analysis...
Integration of geologic, geomorphologic and seismologic data sets is used to reconstruct the recent tectonic evolution active deformation pattern in Val d'Agri area, located seismically axial sector Southern Apennines (Italy). The western portion thrust belt has been affected by Pliocene—Quaternary extension during easterly roll-back crustal delamination Adriatic slab. bulk Quaternary accommodated SW-dipping oblique normal faults, which have attained mature morphologic structural features...
The outermost, NE-verging fronts of the Northern Apennines (Italy) are overlain by a thick syntectonic sedimentary wedge filling up basin beneath Po Plain. Due to fast sedimentation rates and comparatively low tectonic rates, generally buried. Evidence for their activity includes scattered historical instrumental earthquakes drainage anomalies controlled growing buried anticlines. largest earthquakes, Mw 5.8, associated with active compression, GPS-documented shortening rate <1 mm/a.We used...
The Southern Apennines range of Italy presents significant challenges for active fault detection due to the complex structural setting inherited from previous contractional tectonics, coupled very recent (Middle Pleistocene) onset and slow slip rates normal faults. As shown by Irpinia Fault, source a M6.9 earthquake in 1980, major faults might have small cumulative deformation subtle geomorphic expression. A multidisciplinary study including morphological‐tectonic, paleoseismological,...
We investigate the role of Africa‐Eurasia convergence in recent tectonic evolution central Mediterranean. To this end we focused on two sectors Adriatic‐Hyblean foreland Apennine‐Maghrebian chain as they allow evidence for relative plate motions to be analyzed aside from masking effect other more local phenomena (e.g., subduction, building, etc.). present a thorough review data and interpretations major shear zones cutting these sectors: E‐W Molise‐Gondola Adriatic N‐S Vizzini‐Scicli...

Abstract We adopted a multidisciplinary approach to investigate the seismotectonic scenario of 30 October 2016, M w 6.5, Norcia earthquake, largest shock 2016–2017 central Italy earthquake sequence. First, we used seismological and geodetic data infer dip main slip patch seismogenic fault that turned out be rather low‐angle (~37°). To evaluate whether this is an acceptable for source, modeled deformation using single‐ multiple‐fault models deduced from aftershock pattern analyses. These show...
The study of the occurrence and incidence environmental coseismic phenomena is becoming an increasingly demanding fundamental need for seismic hazard evaluation risk reduction. Landslides triggered by earthquakes are most diffuse can cause significant long-lasting impacts losses across area affected earthquake shaking. combination relatively frequent release with a very high landslide susceptibility, makes Italian territory especially prone to earthquake-induced landslides.The CFTIlandslides...
<p>On May 20 and 29, 2012, two earthquakes of magnitudes 5.9 5.8 (Mw), respectively, their aftershock sequences hit the central Po Plain (Italy), about 40 km north Bologna. More than 2,000 sizable aftershocks were recorded by Isti-tuto Nazionale di Geofisica e Vulcanologia (INGV; National Institute Geophysics Volcanology) Seismic Network (http://iside.rm.ingv.it/). The sequence was generated pure compressional faulting over blind thrusts western Ferrara Arc, it involved a 50-km-long...
High-resolution, single-channel seismic and multibeam bathymetry data collected at the Amendolara Ridge, a key submarine area marking junction between Apennine collision belt Calabrian subduction forearc, reveal active deformation in supposedly stable crustal sector. New data, integrated with existing multichannel profiles calibrated oil-exploratory wells, show that middle to late Pleistocene sediments are deformed growth folds above blind oblique-reverse faults bound regional pop-up. Data...
In recent years, new approaches for developing earthquake rupture forecasts (ERFs) have been proposed to be used as an input probabilistic seismic hazard assessment (PSHA). Zone- based with seismicity rates derived from catalogs are commonly in many countries the standard national models. Italy, a single zone- ERF is currently basis official model. this contribution, we present eleven ERFs, including five zone-based, two smoothed seismicity-based, fault- based, and geodetic-based, PSH model...
