Structural Controls on Splay Fault Rupture Dynamics During Cascadia Megathrust Earthquakes
AGU Advances, Volume 6, Issue 6, December 2025.Abstract Great subduction earthquakes (Mw ≥ 8.0) can generate devastating tsunamis by rapidly displacing the seafloor and overlying water column. These potentially tsunamigenic seafloor offsets result from coseismic fault slip and deformation beneath or within the accretionary wedge. The mechanics of these shallow rupture phenomena and their dependence

Flutes, megaflutes and erosional bedforms: a reappraisal of their dynamics [PDF]
, 2010 Erosional bedforms in deep-sea environments record the passage of highly erosive turbidity currents that are often voluminous and fully bypassing. This investigation focuses upon a subset of erosional bedforms that are elliptical in shape, and utilises ...

Range‐Parallel Extension of the Andes in the 2020 Mw 5.7 Humahuaca Earthquake
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.Abstract Normal‐faulting earthquakes in mountain ranges provide important constraints on the dynamics of mountain building. To date, well‐documented examples of range‐parallel extension come primarily from the Tibetan Plateau, limiting our ability to test different models for its cause.

Is the Suez Rift in Its Post‐Rift Phase?
Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.Abstract Failed rifts are widely assumed to enter post‐rift tectonic quiescence after termination of intracontinental rifting, but a comprehensive understanding of their regional morphotectonics is lacking. Our quantitative, rift‐scale geomorphic analyses in the Suez Rift, an archetypal failed rift in Egypt, reveals widespread rifting after presumed ...

Morphotectonic features on Titan and their possible origin
Planetary and Space Science, 2013 Abstract Spectro-imaging and radar measurements by the Cassini–Huygens mission suggest that some of the Saturnian satellites may be geologically active and could support tectonic processes. In particular Titan, Saturn's largest moon, possesses a complex and dynamic geology as witnessed by its varied surface morphology resulting from aeolian, fluvial,

Tectonics, Volume 44, Issue 10, October 2025.Abstract In a subduction zone, variability in the buoyancy and structure of the downgoing plate impacts deformation patterns in the overriding plate. Thick and buoyant lithosphere or smaller‐scale indentors entering the trench can lead to significant relief development and exhumation. To investigate such processes, we target the Cenozoic reorganization

Controls on Water‐Magma Interactions at Hydraulically‐Charged Volcanic Islands
Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.Abstract The interaction of rising magma with groundwater can produce phreatomagmatic explosions, which, given their enhanced explosivity and unpredictability, increase the hazard potential of volcanic eruptions. To investigate the link between groundwater occurrence and phreatomagmatism, we compare the volcanic record of Flores Island (Azores) with ...

Morphotectonics of the Padul-Nigüelas Fault Zone, southern Spain
Annals of Geophysics, 2014 The Padul-Nigüelas Fault Zone (PNFZ) is situated at the south-western mountain front of the Sierra Nevada (southern Spain) in the Internal Zone of the Betic Cordilleras and belongs to a NW-SE trending system of normal faults dipping SW.

Morphotectonics of mass movements on slopes
Journal of Nepal Geological Society, 2000 The study describes the neotectonic effects on morphology of mass movements. Whilst the external (meteorological or seismic) processes are the immediate triggers of mass movements, their location and orientation is pre-designed by the tectonics of the area. The direction of mass movement is naturally in the direction down the slope of the valleys.
