Spatial variability of denudation rates and transient landscape adjustment in low‐deforming mountains (the Strengbach catchment, Vosges Mountains, France)

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Erosion across the landscape is described at first order by a limited number (nine) of homogenous geomorphological and lithological domains. Using a dense set of basin wide denudation rates, it is possible to retrieve the contribution of each litho‐morpho‐domains as a function of their respective surface.

Seismic anisotropy in the D″ layer

Geophysical Research Letters, 1995
We present observations of diffracted SV (SVd) for a path between the Fiji‐Tonga islands and the eastern coast of North America at distances greater than 110°. Observed features of S diffracted suggest that coupling between SVd and SHd can be ruled out as a first order effect for this path.

Probabilistic Hazard Assessment of Coseismic Elastic Surface Deformation for the Leech River Valley–Devil's Mountain Fault System Using Stochastic Source Modeling

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study investigates the effect of incorporating the Devil's Mountain Fault (DMF) and its interaction with the Leech River Valley Fault (LRVF) on the elastic surface deformation hazard in and near the city of Victoria, British Columbia, Canada. Previously, the surface deformation hazard of the region has been characterized by considering the LRVF ...

Seismic anisotropy in western Tibet

Geophysical Research Letters, 2005
Teleseismic SKS data collected by a temporary broadband array across western Tibet are analysed to constrain shear‐wave splitting parameters. Small delay anisotropy is detected, with a rotation of the fast axis azimuth from 40°E in the Tarim basin west of Yecheng to more easterly values between Hotien and Shiquanhe.

A Coupled Extended Finite Element–Cohesive Zone Model for Hydraulic Fracture Propagation Under Poroelastic Effects Across Different Propagation Regimes

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4518-4540, 10 August 2026.
ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...

Numerical Modeling of Geological Fault Reactivation Using Sequential Coupling Strategies

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4339-4359, 10 August 2026.
ABSTRACT The interaction between fluid flow and mechanical deformation in fault zones can lead to processes of fault reactivation, triggering potential geomechanical problems such as seismicity, well collapse, fluid migration to shallower layers, and aggravated surface subsidence.

The Viscoelastic Behaviour of Auxetic Metamaterials

physica status solidi (b), Volume 263, Issue 8, August 2026.
Stretch‐only auxetic unit‐cell viscoelastic models are extended from elastic honeycomb and keyway lattices using Maxwell and standard‐linear‐solid representations. Different horizontal and oblique relaxation responses make Poisson's ratio time‐ and frequency‐dependent, enabling tuneable auxetic behaviour for damping and adaptive structures.

Dislocation creep may control bridgmanite deformation in the Earth’s lower mantle

Communications Earth & Environment
Seismic anisotropy in the Earth’s lower mantle, particularly around subduction zones, is commonly attributed to deformation by dislocation creep, yet much of the lower mantle appears nearly isotropic.

Can Domain‐Informed Design Improve Neural Spatio‐Temporal Point Processes for Earthquake Forecasting?

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract Statistical earthquake forecasting models, such as the Epidemic‐type Aftershock Sequence (ETAS), embed decades of empirical knowledge and assumptions about earthquake triggering, clustering, and catalog completeness. In contrast, neural spatio‐temporal point process (STPP) models often treat seismicity as generic spatiotemporal data without ...

Constraining the Permeability and Outer‐Rise Hydration at the Central America Margin

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Subduction zones are important drivers of Earth's geochemical evolution; the presence of water within the subduction system has substantial implications for geohazards, including the style of seismicity and the volume of magma generated at arc volcanoes.
