Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Alaska's tectonic complexity makes it ideal for probing upper mantle deformation. We present a 3D shear‐wave anisotropy model obtained by inverting 7,985 SKS splitting intensity measurements from 261 broadband stations using 941 events from 2000 to 2023.

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract The Northeastern (NE) Tibet, as the front of plateau growth, widely absorbs northeastward extrusion, leading to significant uplift and forming a basin‐mountain tectonic framework. However, it remains unclear how the crust of NE Tibet deformed in response to the far‐field effects of the India‐Eurasia collision.

Permeability Enhancement by Slow Faulting Under High Pore Fluid Pressure
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract The morphology of fault zones formed by slow faulting is markedly different from that of brittle faulting. In this study, we quantify the three‐dimensional (3D) pore distribution and permeability structures of two rock samples that have been deformed to failure by slow and brittle faulting, respectively.

A Review of Seismic Anisotropy
, 2016 Lithosphere is usually modeled as a layered isotropic medium. However, in reality, upper mantle is anisotropic as evidenced by the azimuthal dependence of P and S wave propagation speed. Probable causes of the observed seismic wave propagation anisotropy include the aligned crystal structure of minerals, aligned cracks and fractures. This anisotropy in

Flow‐Dependent Inertial Permeability Defines Crossover Between Darcy and Forchheimer Flow Regimes
Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract We present mechanistic evidence that the Forchheimer inertial permeability coefficient (β $\beta $) is flow‐dependent in the weak‐to‐intermediate inertia crossover regime, governed by pore‐scale eddy growth‐to‐confinement dynamics. In contrast to classical theory, β $\beta $ attains steady‐state (βs ${\beta }_{s}$) asymptotically in the ...

Ambient‐Noise Multicomponent Multimodal Dispersion Characteristics in Thick Sedimentary Basins
Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Ambient noise cross‐correlations enable the extraction of multimodal surface waves, yet resolving their complex dispersion characteristics is essential for robust subsurface imaging. Using dense array data from the North China Plain, we resolve multicomponent multimodal Rayleigh and Love wave dispersion with unprecedented detail.

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.Abstract Blind faults pose significant seismic hazards because they remain hidden beneath the surface and are often unrecognized until they generate large earthquakes. High‐resolution shallow velocity models are essential for imaging these blind structures.

Shear-wave attenuation anisotropy: a new constraint on mantle melt near the Main Ethiopian Rift
SeismicaThe behaviour of fluids in preferentially aligned fractures plays an important role in a range of dynamic processes within the Earth. In the near-surface, understanding systems of fluid-filled fractures is crucial for applications such as geothermal ...
