Short summary
The 2 June 1994 Java tsunami earthquake ruptured in a seismically quiet subduction zone and generated a larger-than-expected tsunami. Here, we re-process a seismic line across the rupture area. We show that a subducting seamount is located up-dip of the mainshock in a region that did not rupture during the earthquake. Seamount subduction modulates the topography of the marine forearc and acts as a seismic barrier in the 1994 earthquake rupture.

The Ligurian Sea opened ~30–15 Ma during SE migration of the Calabrian subduction zone. Using ambient seismic noise from stations on land and at the ocean bottom, we calculated a 3D shear-velocity model of the Ligurian Basin. In keeping with existing 2D studies, we find a shallow crust–mantle transition at the SW basin centre that deepens towards the northeast, Corsica, and the Liguro-Provençal coast. We observe a separation of SW and NE basins. We do not observe high crustal vP/vS ratios.

Short summary
We analyse broadband ocean bottom seismometer data of the AlpArray OBS network in the Ligurian Basin. Two earthquake clusters with thrust faulting focal mechanisms indicate compression of the rift basin. The locations of seismicity suggest reactivation of pre-existing rift structures and strengthening of crust and uppermost mantle during rifting-related extension. Slightly different striking directions of faults may mimic the anti-clockwise rotation of the Corsica–Sardinia block.

The Ligurian Sea opened ~30–15 Ma during the SE migration of the Calabrian subduction zone. Seismic travel time tomography reveals the absence of oceanic crust, documenting that the extension of continental lithosphere stopped before seafloor spreading initiated. The extension led to extreme crustal thinning and possibly exhumed mantle accompanied by syn-rift sedimentation. Our new interpretation of the crust's nature is important for plate reconstruction modelling related to the Alpine orogen.

The nature of the Ionian Sea crust has been the subject of scientific debate for more than 30 years. Seismic data, recorded on ocean bottom instruments, have been analysed and support the interpretation of the Ionian Abyssal Plain as a remnant of the Tethys oceanic lithosphere with the Malta Escarpment as a transform margin and a Tethys opening in the NNW–SSE direction.

Short summary
We use numerical models to study the stresses arising from gravitational potential energy (GPE) variations and shear tractions associated with mantle convection in the Zagros–Iran region. The joint models predicted consistent deviatoric stresses that can explain most of the deformation indicators. Stresses associated with mantle convection are found to be higher than those from GPE, thus indicating the deformation in this region may primarily be caused by the mantle, except in eastern Iran.

The present study shows evidence of fault systems (large cracks in the Earth's crust) hundreds to thousands of kilometers long and several kilometers thick extending from northwestern Russia to the northern Norwegian Barents Sea and the Svalbard Archipelago using seismic, magnetic, and gravimetric data. The study suggests that the crust in Svalbard and the Barents Sea was already attached to Norway and Russia at ca. 650–550 Ma, thus challenging existing models.

This work analyses the density structure of the continental forearc in the northern segment of the 1960 Mw 9.6 Valdivia earthquake. Results show a segmentation of the continental wedge along and perpendicular to the margin. The extension of the less rigid basement units conforming the marine wedge and Coastal Cordillera domain could modify the process of stress loading during the interseismic periods. This analysis highlights the role of the overriding plate on the seismotectonic process.

By using seismic data and fieldwork, this contribution shows that soft, coal-rich sedimentary rocks absorbed most of early Cenozoic, Eurekan, contractional deformation in central Spitsbergen, thus suggesting that no contractional deformation event is needed in the Late Devonian to explain the deformation differences among late Paleozoic sedimentary rocks. It also shows that the Billefjorden Fault Zone, a major crack in the Earth's crust in Svalbard, is probably segmented.

A multi-scale analysis of aeromagnetic data combining tilt derivative, Euler deconvolution, upward continuation, and 2.75D modelling was applied over Cameroon between the latitudes 5°30'–6° N and the longitudes 13°30'–14°45' E. Major families of faults oriented ENE–WSW, E–W, NW–SE, and N–S with a NE–SW prevalence were mapped. Depths of interpreted faults range from 1000 to 3400 m, mylonitic veins were identified, and 2.75D modelling revealed fault depths greater than 1200 m.

To place constraints on the mantle deformation beneath the Central Alps and the greater Alpine region, we analysed the appropriate seismic signal recorded by more than 100 stations, belonging to AlpArray and to other permanent networks. We took a picture of the imprinting that Alpine orogen history and related subductions left at depth, with a mainly orogen-parallel mantle deformation from Western Alps to Eastern Alps, but also N to S from the Po Plain to the Rhine Graben.

We present an open-source software framework for fast and flexible forward modelling of seismic and acoustic wave phenomena and elastic deformation. It supports a wide range of applications across volcanology, seismology, and geodesy to study earthquakes, volcanic processes, landslides, explosions, mine collapses, ground shaking, and aseismic faulting. The framework stimulates reproducible research and open science through the exchange of pre-calculated Green's functions on an open platform.

Short summary
We quantify the effects that 3-D fractures with realistic distributions of aperture have on seismic wave attenuation and velocity dispersion. Attenuation and dispersion are caused by fluid pressure diffusion between the fractures and the porous background. We show that (i) both an increase in the density of contact areas and a decrease in their correlation length reduce attenuation and (ii) a simple planar fracture can be used to emulate the seismic response of realistic fracture models.

Short summary
Plate-scale rifting is frequently expressed by the subsidence of structural basins along an axis, but postdating tectonic and magmatic activity mostly obscures them. A 3-D subsurface imaging and facies analysis down to 1 km reveals uniquely preserved Galilean basins subsiding along a failing rift front in two main stages. Rifting within a large releasing jog (20–9 Ma), followed by localized grabenization off the Dead Sea fault plate boundary (9–5 Ma), prevents them from dying out peacefully.

Short summary
Geological interpretations based on seismic depth images depend on an accurate subsurface velocity model. Reflection tomography is one method to iteratively update a velocity model based on depth error analysis. We used a warping method to estimate closely spaced data-driven depth error displacement fields. The application to a multichannel seismic line across the Sunda subduction zone illustrates the approach which leads to more accurate images of complex geological structures.
