Short summary
Considering all mapped faults in Italy, empirical scaling laws between fault dimensions and earthquake magnitude are used at the national scale. Results are compared with earthquake catalogues. The consistency between our results and the catalogues gives credibility to the method. Some large differences between the two datasets suggest the validation of this experiment elsewhere.

This paper reports a multiproxy approach to reconstruct the depth, timing, and extent of the past fluid flow during the formation of a fold-and-thrust belt in the Northern Apennines, Italy. The unique combination of paleopiezometry and absolute dating returns the absolute timing of the sequence of deformation. Combined with burial models, this leads to predict the expected temperatures for fluid, highlighting a limited hydrothermal fluid flow we relate to the large-scale subsurface geometry.

Short summary
Short summary
Rocks often contain fracture networks, which can strongly affect subsurface fluid flow and the strength of a rock mass. Through fieldwork and workshops we show that people report a different number of fractures from the same sample area of a fracture network. This variability results in significant differences in derived fracture statistics, which are often used as inputs for geological models. We suggest protocols to recognise, understand, and limit this effect on fracture data collection.

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.

Short summary
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.

This study investigates Cenozoic deformation during cooling and exhumation of the Tauern metamorphic and structural dome, Eastern Alps, through Th–Pb dating of fissure monazite-(Ce). Fissure (or hydrothermal) monazite-(Ce) typically crystallizes in a temperature range of 400–200 °C. Three major episodes of monazite growth occurred at approximately 21, 17, and 12 Ma, corroborating previous crystallization and cooling ages.

Here we discuss the validity of so-called “break-up” markers along the Newfoundland margin, challenging their perceived suitability for plate kinematic reconstructions of the southern North Atlantic. We do this on the basis of newly available seismic transects across the Southern Newfoundland Basin. Our new data contradicts current interpretations of the extent of oceanic lithosphere and illustrates the need for a differently constraining the plate kinematics of the Iberian plate pre M0 times.

In this paper, we investigate the physical mechanisms of tectonic nappe formation by high-resolution numerical modeling. Tectonic nappes are key structural features of many mountain chains which are packets of rocks displaced, sometimes even up to 100 km, from their original position. However, the physical mechanisms involved are not fully understood. We solve numerical equations of fluid and solid dynamics to improve our knowledge. The results are compared with data from the Helvetic Alps.

We propose a new exploration of the concept of
spontaneouslithospheric collapse at a transform fault (TF) by performing a large study of conditions allowing instability of the thicker plate using 2-D thermomechanical simulations. Spontaneous subduction is modelled only if extreme mechanical conditions are assumed. We conclude that spontaneous collapse of the thick older plate at a TF evolving into mature subduction is an unlikely process of subduction initiation at modern Earth conditions.

Short summary
Based on own and published age data, we infer tectonic pulses along-strike the northern rim of the Central Alps between 12–4 million years. Although lithologic variations largely influence the local deformation pattern, the tectonic signal is remarkably consistent all the way from Lake Geneva to Salzburg. This might result from a deep-seated tectonic force and marks a change from dominantly vertical to large-scale horizontal tectonics in the late stage of Alpine orogeny.

Three-dimensional numerical modelling of geodynamic processes may benefit strongly from using realistic 3-D starting models that approximate, e.g. natural subduction settings in the geological past or at present. To this end, we developed the Geodynamic World Builder (GWB), which enables relatively straightforward parameterization of complex 3-D geometric structures associated with geodynamic processes. The GWB is an open-source community code designed to easily interface with geodynamic codes.

Subduction-transform edge propagator (STEP) faults are the locus of continual lithospheric tearing at the edges of subducted slabs, resulting in sharp changes in the lithospheric thickness and triggering lateral and/or near-vertical mantle flow. Here, we study upper mantle rocks recovered from a STEP fault context by < 4 Ma alkali volcanism. We reconstruct how the microstructure developed during deformation and coupled melt–rock interaction, which are promoted by lithospheric tearing at depth.

This work was inspired by an effort to numerically reproduce laboratory models of extension tectonics. We tested various set-ups to find a suitable analogue model and in the process systematically charted the impact of set-ups and boundary conditions on model results, a topic poorly described in existing scientific literature. We hope that our model results and the discussion on which specific tectonic settings they could represent may serve as a guide for future (analogue) modeling studies.

On one of the least studied boundaries between tectonic plates (North America–Okhotsk in northeastern Russia), which moves very similarly to the famous San Andreas fault in California, we have found the traces of earthquakes from the recent past, but before the time of historical records. This makes us a little more sure that the fault is still the place where movement between the plates takes place, and when it happens again, there could be dangerous earthquakes.

We used a 2-D thermomechanical code to simulate the evolution of an orogen. Our aim was to study the interaction between tectonic and surface processes in orogenic forelands. We found that an increase in the sediment input to the foreland results in prolonged activity of the active frontal thrust. Such a scenario could occur naturally as a result of increasing relief in the orogenic hinterland or a change in climatic conditions. We compare our results with observations from the Alps.

The Caledonian mountains formed when Baltica and Laurentia collided around 450–400 million years ago. This work describes the history of the rocks and the dynamics of that continental collision through space and time using field mapping, estimated pressures and temperatures, and age dating on rocks from northern Norway. The rocks preserve continental collision between 440–430 million years ago, and an unusual pressure–temperature evolution suggests unusual tectonic activity prior to collision.

We used microscopy and electron backscatter diffraction to analyse the deformation behaviour of feldspar at greenschist facies conditions in mylonitic pegmatites of the Austroalpine basement. There are strong uncertainties about feldspar deformation, mainly because of the varying contributions of different deformation processes. We observed that deformation is mainly the result of coupled fracturing and dislocation glide, followed by growth and granular flow.

Vast amounts of methane are released to the oceans at continental margins (seepage). The mechanisms controlling when and how much methane is released are not fully understood. In the Fram Strait seepage may be affected by complex tectonic processes. We modelled the stress generated on the sediments exclusively due to the opening of the mid-ocean ridges and found that changes in the stress field may be controlling when and where seepage occurs, which has implications for seepage reconstruction.

Short summary
Successive earthquakes on a single fault are not perfectly periodic in time. There is some natural random variability. This leads to variations in estimated fault slip rates over short timescales though the longer-term mean slip rate stays constant, which may cause problems when comparing slip rates at different timescales. This paper is the first to quantify these effects, demonstrating substantial variation in slip rates over a few to tens of earthquakes, but much less at longer timescales.

This research is dedicated to the study of poorly understood coal-bearing Mississippian (ca. 360–325 Ma) sedimentary rocks in central Spitsbergen. Our results suggest that these rocks were deposited during a period of widespread extension involving multiple fault trends, including faults striking subparallel to the extension direction, while overlying Pennsylvanian rocks (ca. 325–300 Ma) were deposited during extension localized along fewer, larger faults.

In order to assess the influence of deformational processes within accretionary prisms, we track the evolution of the energy budget. We track the consumption of energy stored in internal deformation of the host rock, energy expended in frictional slip, energy used in uplift against gravity and total energy input. We find that the energy used in internal deformation is < 1% of the total and that the energy expended in frictional slip is the largest portion of the budget.

Early Triassic sediments in the northeastern North Chian Craton resulted from the subduction of the Paleo-Asian oceanic plate and collision between the North China and Yangtze cratons. Late Triassic sediments resulted from the final closure of the Paleo-Asian Ocean in the Middle Triassic and exhumation of the Su–Lu Orogenic Belt. Early Jurassic change in provenance was related to the uplift of the Xing'an–Mongolia Orogenic Belt and the subduction of the Paleo-Pacific Plate.

In this modeling study, we investigate rock uplift at plate corners (syntaxes). These are characterized by a unique bent geometry at subduction zones and exhibit some of the world's highest rock uplift rates. We find that the style of deformation changes above the plate's bent section and that active subduction is necessary to generate an isolated region of rapid uplift. Strong erosion there localizes uplift on even smaller scales, suggesting both tectonic and surface processes are important.

We couple Himalayan tectonics to numerical simulations to show how upward-tapering channel (UTC) flow can be used to explain the evidence. The simulations predict high tectonic overpressure (TOP > 2), which increases exponentially with a decrease in UTC mouth width, and with increase in velocity and channel viscosity. The highest TOP occurs at depths < −60 km, which, combined with the flow in the UTC, forces high-pressure rocks to exhume along the channel’s hanging wall, as in the Himalayas.

Short summary
The Ionian Sea in southern Italy is at the center of active convergence between the Eurasian and African plates, with many known
Mw > 7.0 earthquakes. Here, a recently discovered mud volcano (called the Bortoluzzi Mud Volcano or BMV) was surveyed during the Seismofaults 2017 cruise (May 2017). The BMV is the active emergence of crustal fluids probably squeezed up during the seismic cycle. As such, the BMV may potentially be used to track the seismic cycle of active faults.
