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

open access: yesJournal 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.

Imaging Near‐Surface Bedrock Fracturing and Fluid Pathways Using Seismic Attenuation and Velocity From Viscoacoustic Full‐Waveform Inversion of Refraction Data

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Seismic attenuation provides sensitivity to fracture density, fluid saturation, and pore geometry that complements velocity, enabling quantitative imaging of fracture architecture and associated fluid‐pathways in near‐surface bedrock. Yet high‐resolution attenuation models remain rare in refraction studies due to amplitude‐fidelity and ...

Transformation elasticity and anelasticity

open access: yes, 2020
We present a theoretical framework for studying a large class of elastic and anelastic problems in nonlinear solids. We specifically use the transformation properties of nonlinear and linearized elasticity in this theory.

Thermochemical Controls on the X, 410, and 660 Discontinuities in the Central Mediterranean

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract The mantle beneath the Central Mediterranean is thermally and compositionally heterogeneous, as indicated by fragmented and locally stagnant slabs in tomographic images and HIMU‐like anorogenic magmatism. Mantle discontinuities are sensitive to both temperature and composition, and thus provide a way to quantify these heterogeneities.

Estudio de la sensibilidad a la velocidad de deformación en régimen superplástico del inconel 718 mediante ensayos con perturbación cíclica de la velocidad de deformación

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2004
The imposition of a sinusoidal perturbation of variable frequency to the strain rate of a material subjected to a monotonic tensile test is an easy technique to study the kinetics of plastic deformation that has been scarcely used.

Compressional wave dispersion due to rock matrix stiffening by clay squirt flow

open access: yesGeophysical Research Letters, 2016
The standard Biot‐Gassmann theory of poroelasticity fails to explain strong compressional wave velocity dispersion experimentally observed in 12 tight siltstone with clay‐filled pores.

Accuracy Assessment of Ocean Tide Models in the Eastern China Marginal Seas Using Tide Gauge and GPS Data

open access: yesJournal of Marine Science and Engineering
Accurate ocean tide models are required to remove tidal loading effects in geophysical research. Beyond a mere intercomparison, the accuracy of eight modern global models (DTU10, EOT20, FES2014b, FES2022b, GOT4.10c, HAMTIDE11a, OSU12, TPXO10-atlas-v2 ...

Fortnightly Earth Rotation, Ocean Tides, and Mantle Anelasticity

open access: yes, 2011
Sustained accurate measurements of earth rotation are one of the prime goals of Global Geodetic Observing System (GGOS). We here concentrate on the fortnightly (Mf) tidal component of earth-rotation data to obtain new results concerning anelasticity of ...

The Effect of Anelasticity on Periods of the Earth's Free Oscillations (Toroidal Modes) [PDF]

open access: yes, 1975
It is known that the anelastic properties of the Earth characterized by a ‘Q’ structure will affect the periods of free oscillation. It is generally considered that the effect is negligible compared to the other perturbing effects due to rotation ...
