Short summary
We performed a paleoseismological study on the Mt. Morrone active fault, which constitutes one of the most problematic structures of the central Apennines in terms of large-earthquake probability. Information on historical seismicity is relatively few and the paleoseismological record is limited only to the northern portion of the fault. We investigated four trenches and we recovered the occurrence of three events over the last 5–6 kyrs, suggesting an average recurrence interval of 1800 years.

We built six observatory stations in central Italy to monitor a fault potentially capable of generating a strong earthquake. Each site has 80–160 m deep wells equipped with strainmeters and seismometers. At the surface, we placed GNSS antennas and seismic and meteorological sensors. All data, which are open access for the scientific community, will help us to better understand the complex physical and chemical processes that lead to the generation of the full range of slow and fast earthquakes.

Short summary
The paper discusses geological aspects, methodological procedures of seismic microzonation and the implications on seismic site response of an urbanized area in a geologic environment of deep continental basin (the Avezzano town in the Fucino continental basin of central Apennines, Italy). The paper is of potential interest for the geological community and also for non-geologist scientists/technicians/decision makers working in the field of earthquake hazard.

We investigate the along-strike variation in volcanics on the Pelotas segment of the Brazilian margin created during continental breakup and formation of the southern South Atlantic. We show that the volume of volcanics strongly controls the amount of space available for post-breakup sedimentation. We also show that breakup varies along-strike from very magma-rich to magma-normal within a relatively short distance of less than 300 km. This is not as expected from a simple mantle plume model.

The rotation of the principal stress axes in a fault structure because of a rock stiffness contrast has been investigated for the impact of the ratio of principal stresses, the angle between principal stress axes and fault strike, and the ratio of the rock stiffness contrast. A generic 2D geomechanical model is employed for the systematic investigation of the parameter space.

Rifting and the break-up of continents are key aspects of Earth’s plate tectonic system. A thorough understanding of the geological processes involved in rifting, and of the associated natural hazards and resources, is of great importance in the context of the energy transition. Here, we provide a coherent overview of rift processes and the links with hazards and resources, and we assess future challenges and opportunities for (collaboration between) researchers, government, and industry.

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 show that the 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 that is mainly driven by the southward migration of the Ionian slab roll-back.

In this contribution, 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 using geophysical data and reviewed the available geological data. We interpret 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.

We investigate the upper-crustal structure of the Rukwa–Tanganyika rift zone in East Africa, where the Tanganyika rift interacts with the Rukwa and Mweru-Wantipa rifts, coinciding with abundant seismicity at the rift tips. Seismic velocity structure and patterns of seismicity clustering reveal zones around 10 km deep with anomalously high Vp / Vs ratios at the rift tips, indicative of a localized mechanically weakened crust caused by mantle volatiles and damage associated with bending strain.

I present a synthesis of the continent–ocean boundaries of the southern North Atlantic Ocean, as probed using seismic methods for rock velocity estimation, to assess their deep structures from the crust to the upper mantle and to discuss how they were formed.

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.

We postulate that the observed spatial distribution of large earthquakes in active convergence zones, organized in segments where large events are repeated every 100–300 years, depends on large scale continental faults and fluid release from the subducting slab. In order to support this model, we use proxies at different spatial and temporal scales (historic seismicity, megathrust slip solutions, inter-seismic cumulative seismicity, GPS/viscous plate coupling, and coast line morphology).

Our study investigates the structural evolution of the Fars Arc in the Zagros Mountain by numerical modeling. We focus on the effects of the interaction between basement faults and salt décollement levels during tectonic inversion, including a rifting and a convergence phase. In conclusion, our results emphasize the importance of considering fault geometry, salt rheology, and basement involvement in understanding the resistance to deformation and seismic behavior of fold-thrust belts.

This work investigates the influence of vertical rheological contrasts on the nucleation and behavior of strike-slip faults, using analogue modelling. The introduction of rheological contrasts was achieved using quartz sand and microbeads grains. The study shows how the strike, type and evolution of the faults strongly depend on the characteristic of the lithology and its contact orientation. The results are comparable with the fault systems observed in the NW of the Iberian Peninsula.

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.

Extension leading to the formation of ocean–continental transition can be highly oblique to the main direction of crustal thinning. Here we explore the case of a continental margin exposed in the Betics that developed in a back-arc setting perpendicular to the direction of the retreating Gibraltar subduction. We show that transtension is the main mode of crustal deformation that led to the development of metamorphic domes and extensional intramontane basins.

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.

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.

Continental rifts form by linkage of individual rift segments and disturb the regional stress field. We use analog and numerical models of such rift segment interactions to investigate the linkage of deformation and stresses and subsequent stress deflections from the regional stress pattern. This local stress re-orientation eventually causes rift deflection when multiple rift segments compete for linkage with opposingly propagating segments and may explain rift deflection as observed in nature.

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.

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.

This study investigates one of the key processes that may lead to the destruction and destabilization of continental tectonic plates: the infiltration of buoyant, hot, molten rock (magma) into the base of the plate. Using simple calculations, I suggest that heating during melt–rock interaction may thermally perturb the tectonic plate, weakening it and potentially allowing it to be reshaped from beneath. Geochemical, petrologic, and geologic observations are used to guide model parameters.

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.

We constructed a three-dimensional numerical geomechanics model to obtain the continuous slip rates of active faults and crustal velocities in the northeastern Tibetan Plateau. Based on the analysis of the fault kinematics in the study area, we evaluated the possibility of earthquakes occurring in the main faults in the area, and analyzed the crustal deformation mechanism of the northeastern Tibetan Plateau.

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.

We have built a community model for the evolution of the Earth's plate–mantle system. Created with open-source software and an open-access plate model, it covers the last billion years, including the formation, breakup, and dispersal of two supercontinents, as well as the creation and destruction of numerous ocean basins. The model allows us to

In this study we present a method to compute a reference pressure based on density structure in which we cast the problem in terms of a partial differential equation (PDE). We show in the context of 3D models of continental rifting that using the pressure as a boundary condition within the flow problem results in non-cylindrical velocity fields, producing strain localization in the lithosphere along large-scale strike-slip shear zones and allowing the formation and evolution of triple junctions.

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.

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.

It illustrates how the destruction of the Caledonian orogen in the Late Devonian–early Carboniferous led to half-graben formation, how they were inverted in the late Carboniferous, how the study area evolved during the formation of the Permo-Mesozoic Polish Basin and how supra-evaporitic structures were inverted in the Late Cretaceous–Paleogene.

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.

The local topographic slope of an accretionary prism is often used to determine the effective friction on subduction megathrust. We investigate how the brittle–ductile and the smectite–illite transitions affect the topographic slope of an accretionary prism and its internal deformation to provide clues to determine the origin of observed low topographic slopes in subduction zones. We finally discuss their implications in terms of the forearc basin and forearc high genesis and nature.

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.

We present an erosion rate analysis on dated rock and sediment from the Northern Apennine Mountains, Italy, which provides new insights on the pattern of erosion rates through space and time. This analysis shows decreasing erosion through time on the Ligurian side but increasing erosion through time on the Adriatic side. We suggest that the pattern of erosion rates is consistent with the present asymmetric topography in the Northern Apennines, which has likely existed for several million years.

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.

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.

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.

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.

Short summary
We integrated geological and geophysical data to study the evolution of a large sector of the central Apennines, in Italy. The adopted approach permitted us to cast light on timing of faults activity over the past about 2 million years. The results we obtained has implication in terms of assessment of seismic sources of strong earthquakes. In particular, we defined which of the investigated faults are able to produce large-magnitude seismic events and which are no longer able.
