Past strong earthquakes can produce topographic deformations, often
memorizedin Quaternary sediments, which are typically studied by paleoseismologists through trenching. Using a ground-penetrating radar (GPR), we unveiled possible buried Quaternary faulting in the Mt. Pollino seismic gap region (southern Italy). We aim to contribute to seismic hazard assessment of an area potentially prone to destructive events as well as promote our workflow in similar contexts around the world.

We propose a methodology useful to evaluate (1) the reliability of a focal mechanism solution inferred by the inversion of seismological data and (2) the performance of a seismic network, operated to monitor natural or induced seismicity, to assess focal mechanism solutions. As a test case, we studied the focal mechanism reliability by using synthetic data computed for ISNet, a local seismic network monitoring the Irpinia fault system (southern Italy).

This paper impacts on knowledge of plate margin deformation and microplate fragmentation in the Central Mediterranean. Seismicity and seismogenic stress, with other geophysical and geological data, deny active rifting in the Sicily Channel and reveal strain distributions in the western Ionian contrasting with models assuming a rigid Apulian-Ionian-Hyblean microplate. We highlight that current oversimplification of lithosphere rheology prevents from appropriate regional geodynamic modeling.

The study identifies evidence for extension south of Tellicherry Arch along the southwestern continental margin of India through the integrated analysis of multichannel seismic and gravity data. The sediment deposition pattern indicates that this extension occurred after the Eocene. We further propose that the anticlockwise rotation of India and the passage of the Réunion plume have facilitated the opening of the Laccadive basin.

This study explores the erosion and exhumation processes and history of early continental crust hidden within the Amazonian Rainforest. This crust forms part of the Amazonian Craton, an ancient continental fragment. Our surprising findings reveal the area underwent rapid early Cretaceous exhumation triggered by tectonic forces. This discovery challenges the traditional perception that cratons are stable and long-lived entities and shows they can deform readily under specific geological contexts.

Stishovite remains stable under mantle conditions and can incorporate various amounts of water in its crystal structure. We provide a systematic review of previous studies on water in stishovite and propose a new model for water solubility of Al-bearing stishovite. Calculation results based on this model suggest that stishovite may effectively accommodate water from the breakdown of hydrous minerals and could make an important contribution to water enrichment in the mantle transition zone.

Alpine tectonic inversion is reviewed for southwestern Iberia, known for its historical earthquakes and tsunamis. High-quality 2D seismic data image 26 faults mapped to a depth exceeding 10 km. Normal faults accommodated important vertical uplift and shortening. They are 100–250 km long and may generate earthquakes with Mw > 8.0. Regions of Late Mesozoic magmatism comprise thickened, harder crust, forming lateral buttresses to compression and promoting the development of fold-and-thrust belts.

New satellite geodetic data (PS-InSAR) evidence a generalized subsidence and an eastward tilting of Southeastern Sicily combined with a local relative uplift along its eastern coast. We perform flexural and elastic modeling, and shows that slab pull force induced by the Ionian slab roll-back and extrado deformation, reproduce the measured surface deformation. Finally, we propose an original seismic cycle model, mainly driven by the southward migration of the Ionian slab roll-back.

We investigate the upper-crustal structure of the Rukwa-Tanganyika Rift Zone, East Africa, where earthquakes anomalously cluster at the tips and axes of active rifts. Rift tip earthquakes collocate with a zone of distributed faulting in exposed crystalline basement. Seismic velocity structure reveals ~10 km-deep zones of anomalously high Vp/Vs ratios at the rift tips representing localized mechanical weakening of the crust, interpreted to be a precursory phase that initiates rift propagation.

The Atlantic Ocean results from the break-up of the palaeocontinent Gondwana. Since then, the Brazilian and African margins record a thick volcanic layers and received a large contribution of sediments recording this process. We show the influence of early volcanics on the sediments deposited later by analysing the Pelotas Margin, south of Brazil. The volume of volcanic layers is not homogeneous along this sector, promoting variation in the space available to accommodate later sediments.

We explore the causal relationship between the arrival of the Afar plume and the initiation of the Afro-Arabian rift. We mapped the rift architecture in the triple junction region from geophysical data and reviewed the available geological temporal evidence. We infer a progressive development of the plume-rift system and suggest an interaction between active and passive mechanisms in which the plume provided a push-force that changed the kinematics of the associated plates.

Intense phase mixing with homogeneously distributed secondary phases and irregular grain boundaries and shapes indicates that metasomatism formed the microstructures predominant in the shear zone of the NW Ronda peridotite. Amphibole presence, olivine crystal orientations, and the consistency to the Beni Bousera peridotite (Morocco) point to OH-bearing metasomatism by small fractions of evolved melts. Results confirm a strong link between reactions and localized deformation in the upper mantle.

Short summary
When a continent is pulled apart, it breaks and forms a series of depressions called rift basins. These basins lie above weakened crust that is then subject to intense deformation during subsequent tectonic compression. Our analogue experiments show that when a system of basins is squeezed in a direction perpendicular to the main trend of the basins, some basins rise up to form mountains while others do not.

The East African Rift System (EARS) is a major plate tectonic feature splitting the African continent apart. Understanding the tectonic processes involved is of great importance for societal and economic reasons (natural hazards, resources). Laboratory experiments allow us to simulate these large-scale processes, highlighting the links between rotational plate motion and the overall development of the EARS. These insights are relevant when studying other rift systems around the globe as well.

Through analogue models and field observations, we investigate how inherited platform–basin geometries control strain localisation, style, and orientation of reactivated and new structures during inversion. Our study shows that the style of evolving thrusts and their changes along-strike are controlled by pre-existing rheological discontinuities. The results of this study are relevant for understanding inversion structures in general and for the European eastern Southern Alps in particular.

A magnetic fabric analysis provides information about the reorientation of magnetic grains and is applied to three sandbox models that simulate different stages of basin inversion. The analysed magnetic fabrics reflect the different developed structures and provide insights into the different deformed stages of basin inversion. It is a first attempt of applying magnetic fabric analyses to basin inversion sandbox models but shows the possibility of applying it to such models.

Continental crust comprises bodies of varying strength, formed through numerous tectonic events. When subject to extension, these areas produce distinct rift and fault systems. We use 3D models to examine how rifts form above
strongand
weakareas of crust. We find that faults become more developed in weak areas. Faults are initially stopped at the boundaries with stronger areas before eventually breaking through. We relate our model observations to rift systems globally.

We study the construction of the Ukrainian Carpathians with LT thermochronology (AFT, AHe, and ZHe) and stratigraphic analysis. QTQt thermal models are combined with burial diagrams to retrieve the timing and magnitude of sedimentary burial, tectonic burial, and subsequent exhumation of the wedge's nappes from 34 to ∼12 Ma. Out-of-sequence thrusting and sediment recycling during wedge building are also identified. This elucidates the evolution of a typical wedge in a roll-back subduction zone.

When a sedimentary basin is subjected to compressional tectonic forces after its formation, it may be inverted. A thorough understanding of such
basin inversionis of great importance for scientific, societal, and economic reasons, and analogue tectonic models form a key part of our efforts to study these processes.

Shales are identified as suitable caprock formations for geolocigal CO2 storage thanks to their low permeability. Here, small-sized shale samples are studied under field-representative conditions with X-ray tomography. The geochemical impact of CO2 on calcite-rich zones is for the first time visualised, the role of pre-existing micro-fissures in the CO2 invasion trapping in the matererial is highlighted, and the initiation of micro-cracks when in contact with anhydrous CO2 is demonstrated.

The Slyne Basin is a sedimentary basin located offshore north-western Ireland. It formed through a long and complex evolution involving distinct periods of extension. The basin is subdivided into smaller basins, separated by deep structures related to the ancient Caledonian mountain-building event. These deep structures influence the shape of the basin as it evolves in a relatively unique way, where early faults follow these deep structures, but later faults do not.

Under tectonic forces, the upper part of the crust can break along different types of faults, depending on the orientation of the applied stresses. Using scaled analogue models, we show that the relative magnitude of compressional and extensional forces as well as the presence of inherited structures resulting from previous stages of deformation control the location and type of faults. Our results gives insights into the tectonic evolution of areas showing complex patterns of deformation.

Old seismic data recently reprocessed with modern software allowed us to study at depth the Late Cretaceous tectonic structures in the Permo-Mesozoic rock sequences in the Sudetes. The structures formed in response to Iberia collision with continental Europe. The NE–SW compression undulated the crystalline basement top and produced folds, faults and joints in the sedimentary cover. Our results are of importance for regional geology and in prospecting for deep thermal waters.

Reactivation of tectonic faults can lead to earthquakes and jeopardize underground operations. The reactivation potential is linked to fault properties and the tectonic stress field. We create 3D geometries for major faults in Germany and use stress data from a 3D geomechanical–numerical model to calculate their reactivation potential and compare it to seismic events. The reactivation potential in general is highest for NNE–SSW- and NW–SE-striking faults and strongly depends on the fault dip.

Short summary
Earthquake extent prediction is limited by our poor understanding of slip deficit patterns. From a mechanical analysis applied along the Chilean margin, we show that earthquakes are bounded by extensive plate interface deformation. This deformation promotes stress build-up, leading to earthquake nucleation; earthquakes then propagate along smoothed fault planes and are stopped by heterogeneously distributed deformation. Slip deficit patterns reflect the spatial distribution of this deformation.

We studied the Gioia Sannitica normal fault (GF) within the southern Matese fault system (SMF) in southern Apennines (Italy). It is a fault with a long slip history that has experienced recent reactivation or acceleration. Present activity has resulted in late Quaternary fault scarps and Holocene surface faulting. The maximum slip rate is ~ 0.5 mm/yr. Activation of the 11.5 km GF or the entire 30 km SMF can produce up to M 6.2 or M 6.8 earthquakes, respectively.

Rare earth elements (REEs) are considered critical mineral resources for future industrial growth due to their short supply and rising demand. This study applied an artificial-intelligence-based technique to target potential REE-deposit hosting areas in western Rajasthan, India. Uncertainties associated with the prospective targets were also estimated to aid decision-making. The presented workflow can be applied to similar regions elsewhere to locate potential zones of REE mineralisation.

Field trips in the Stratigraphy, Structure, Tectonics (SST) course transitioned to a virtual format in Fall 2020, due to the COVID pandemic. Virtual field experiences (VFEs) were developed in web Google Earth and were evaluated in comparison with on-location field trips via an online survey. Students recognized the value of VFEs for revisiting outcrops and noted improved accessibility for students with disabilities. Potential benefits of hybrid field experiences were also indicated.

Molasse deposits, deposited and deformed at the western Alpine front during the Miocene (23 to 5.6 Ma), record the chronology of that deformation. We combine the first precise chronostratigraphy (precision of ∼0.5 Ma) of the Miocene molasse, the reappraisal of the regional structure, and the analysis of growth deformation structures in order to document three tectonic phases and the precise chronology of thrust westward propagation during the second one involving the Belledonne basal thrust.

New images from the multi-national AlpArray experiment illuminate the Alps from below. They indicate thick European mantle descending beneath the Alps and forming blobs that are mostly detached from the Alps above. In contrast, the Adriatic mantle in the Alps is much thinner. This difference helps explain the rugged mountains and the abundance of subducted and exhumed units at the core of the Alps. The blobs are stretched remnants of old ocean and its margins that reach down to at least 410 km.

Past strong earthquakes can produce topographic deformations, often
memorizedin Quaternary sediments, which are typically studied by paleoseismologists through trenching. Using a ground-penetrating radar (GPR), we unveiled possible buried Quaternary faulting in the Mt. Pollino seismic gap region (southern Italy). We aim to contribute to seismic hazard assessment of an area potentially prone to destructive events as well as promote our workflow in similar contexts around the world.

In this paper, we dated fault movements at geological timescales which uplifted the sedimentary successions of the Jura Mountains from below the sea level up to Earth's surface. To do so, we applied the novel technique of U–Pb geochronology on calcite mineralizations that precipitated on fault surfaces during times of tectonic activity. Our results document a time frame of the tectonic evolution of the Jura Mountains and provide new insight into the broad geological history of the Western Alps.

As continental plates collide, mountain belts grow. This study investigated the provenance of rocks from the northwestern segment of the Zagros mountain belt to unravel the convergence history of the Arabian and Eurasian plates. Provenance data synthesis and field relationships suggest that the Zagros Mountains developed as a result of the oceanic crust emplacement on the Arabian continental plate, followed by the Arabia–Eurasia collision and later uplift of the broader region.

Central western Europe underwent a strange episode of lithospheric deformation, resulting in a chain of small mountains that run almost west–east across the continent and that formed in the middle of a tectonic plate, not at its edges as is usually expected. Associated with these mountains, in particular the Harz in central Germany, are marine basins contemporaneous with the mountain growth. We explain how those basins came to be as a result of the mountains bending the adjacent plate.

We combine gravity anomaly and topographic data with observations from thermochronology, metamorphic grades, and the granite inventory to detect patterns of basement block segmentation and differential exhumation along the southwestern Bohemian Massif. Based on our analyses, we introduce a previously unknown tectonic structure termed Cham Fault, which, together with the Pfahl and Danube shear zones, is responsible for the exposure of different crustal levels during late to post-Variscan times.

Several large strike-slip faults in western Slovenia are known to be active, but most of them have not produced strong earthquakes in historical times. In this study we use geomorphology, near-surface geophysics, and fault excavations to show that two of these faults had surface-rupturing earthquakes during the Holocene. Instrumental and historical seismicity data do not capture the strongest events in this area.

A new analogue modelling approach was used to simulate the influence of tectonic extension and tilting of the basin floor on salt tectonics in rift basins. Our results show that downward salt flow and gravity gliding takes place if the flanks of the rift basin are tilted. Thus, extension occurs at the basin margins, which is compensated for by reduced extension and later by shortening in the graben centre. These outcomes improve the reconstruction of salt-related structures in rift basins.

We have analysed the role of deep salt layers during tectonic shortening of a group of sedimentary basins buried below the North Sea. Due to the ability of salt to flow over geological timescales, the salt layers are much weaker than the surrounding rocks during tectonic deformation. Therefore, complex structures formed mainly where salt was present in our study area. Our results align with findings from other basins and experiments, underlining the importance of salt tectonics.

We used laboratory experiments to simulate the early evolution of rift systems, and the influence of structural weaknesses left over from previous tectonic events that can localize new deformation. We find that the orientation and type of such weaknesses can induce complex structures with different orientations during a single phase of rifting, instead of requiring multiple rifting phases. These findings provide a strong incentive to reassess the tectonic history of various natural examples.

Although viscosity of the crust largely exceeds that of magmas, we show, based on the Aegean and Tyrrhenian Miocene syn-kinematic plutons, how the intrusion of granites in extensional contexts is controlled by crustal deformation, from magmatic stage to cold mylonites. We show that a simple numerical setup with partial melting in the lower crust in an extensional context leads to the formation of metamorphic core complexes and low-angle detachments reproducing the observed evolution of plutons.

Constraining the conditions at which rocks form is crucial for understanding geologic processes. For years, the conditions under which rocks from Syros, Greece, formed have remained enigmatic; yet these rocks are fundamental for understanding processes occurring at the interface between colliding tectonic plates (subduction zones). Here, we constrain conditions under which these rocks formed and show they were transported to the surface adjacent to the down-going (subducting) tectonic plate.

The influence and interaction of elastic material properties (Young's modulus, Poisson's ratio), density and low-friction faults on the resulting far-field stress pattern in the Earth's crust is tested with generic models. A Young's modulus contrast can lead to a significant stress rotation. Discontinuities with low friction in homogeneous models change the stress pattern only slightly, away from the fault. In addition, active discontinuities are able to compensate stress rotation.

The former Piemont–Liguria Ocean, which separated Europe from Africa–Adria in the Jurassic, opened as an arm of the central Atlantic. Using plate reconstructions and geodynamic modeling, we show that the ocean reached only 250 km width between Europe and Adria. Moreover, at least 65 % of the lithosphere subducted into the mantle and/or incorporated into the Alps during convergence in Cretaceous and Cenozoic times comprised highly thinned continental crust, while only 35 % was truly oceanic.

We use 2D numerical models to highlight the role of basal drag in subduction force balance. We show that basal drag can significantly affect velocities and evolution in our simulations and suggest an explanation as to why there are no trends in plate velocities with age in the Cenozoic subduction record (which we extracted from recent reconstruction using GPlates). The insights into the role of basal drag will help set up global models of plate dynamics or specific regional subduction models.

Many of the world's hydrocarbon resources are found in rifted sedimentary basins. Some rifts experience multiple phases of extension and inversion. This results in complicated oil and gas generation, migration, and entrapment histories. We present examples of basins in the Western Desert of Egypt and the western Black Sea that were inverted multiple times, sometimes separated by additional phases of extension. We then discuss how these complex deformation histories impact exploration campaigns.

Based on thermochronological data, we infer thrusting along-strike the northern rim of the Central Alps between 12–4 Ma. While the lithology influences the pattern of thrusting at the local scale, we observe that thrusting in the foreland is a long-wavelength feature occurring between Lake Geneva and Salzburg. This coincides with the geometry and dynamics of the attached lithospheric slab at depth. Thus, thrusting in the foreland is at least partly linked to changes in slab dynamics.

We study the Iberian plate motion, from the late Permian to middle Cretaceous. During this time interval, two oceanic systems opened. Geological evidence shows that the Iberian domain preserved the propagation of these two rift systems well. We use geological evidence and pre-existing kinematic models to propose a coherent kinematic model of Iberia that considers both the Neotethyan and Atlantic evolutions. Our model shows that the Europe–Iberia plate boundary was made of two rift systems.

We apply three-dimensional (3D) thermo-mechanical numerical simulations of the shortening of the upper crustal region of a passive margin in order to investigate the control of 3D laterally variable inherited structures on fold-and-thrust belt evolution and associated nappe formation. The model is applied to the Helvetic nappe system of the Swiss Alps. Our results show a 3D reconstruction of the first-order tectonic evolution showing the fundamental importance of inherited geological structures.

The Alboran Sea is one of the most active region of the Mediterranean Sea. There, the basin architecture records the effect of the Africa–Eurasia plates convergence. We evidence a Pliocene transpression and a more recent Pleistocene tectonic reorganization. We propose that main driving force of the deformation is the Africa–Eurasia convergence, rather than other geodynamical processes. It highlights the evolution and the geometry of the present-day Africa–Eurasia plate boundary.

A magnitude 5.3 reverse-faulting earthquake in September 2018 near Lake Muir in southwest Western Australia was followed after 2 months by a collocated magnitude 5.2 strike-slip event. The first event produced a ~ 5 km long and up to 0.5 m high west-facing surface rupture, and the second triggered event deformed but did not rupture the surface. The earthquake sequence was the ninth to have produced surface rupture in Australia. None of these show evidence for prior Quaternary surface rupture.

Injection of vertical sheets of magma (dyke swarms) controls tectonic and volcanic processes on Earth and other planets. Yet we know little of the 3D structure of dyke swarms. We use seismic reflection data, which provides ultrasound-like images of Earth's subsurface, to study a dyke swarm in 3D for the first time. We show that (1) dyke injection occurred in the Late Jurassic, (2) our data support previous models of dyke shape, and (3) seismic data provides a new way to view and study dykes.

Short summary
The Pollino region is a highly seismic area of Italy. Increasing the geological knowledge on areas like this contributes to reducing risk and saving lives. We reconstruct the 3D model of the faults which generated the 2010–2014 seismicity integrating geological and seismological data. Appropriate relationships based on the dimensions of the activated faults suggest that they did not fully discharge their seismic potential and could release further significant earthquakes in the near future.
