Bearing Capacity of Tension Steel Piles in Thinly Inter‐Layered Soils: Numerical Class‐A Prediction vs. Field Measurements

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 3, Page 1430-1450, 25 February 2026.
ABSTRACT This study investigates the bearing capacity of tension piles and pile‐soil interaction during loading. Discrepancies between predicted and measured bearing capacities in previous tests motivated the study, where analytical methods showed considerable scatter and uncertainties in design.

Brittle and Crystal‐Plastic Defect Dynamics of Calcite Single Crystals

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.
Abstract The response of Earth materials to stress has a first‐order control on solid‐Earth dynamics ranging from earthquakes to volcanic eruptions to landslides. Thus, understanding the rheological behavior of minerals, preferentially at a micro‐scale to allow process‐based upscaling, has broad applications across the Earth sciences.

Mechanical Characterization and Damage Modeling of Adobe Blocks Stabilized With Natural Plant Fibers

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
This study evaluates the mechanical performance of adobe blocks stabilized with natural plant fibers derived from Hyparrhenia hirta (HH) and Stipa offneri (SO). To this end, adobe specimens were fabricated by incorporating plant fibers into the soil matrix at contents ranging from 0% to 1% by weight of soil, with increments of 0.2%.

A Possible Tsunamigenic Near‐Trench Strike‐Slip Fault, Offshore North Ecuador–South Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Seismic reflection and bathymetry collected along the Ecuador–Colombia obliquely convergent margin allow the first characterization of the NNE‐trending, near‐trench strike‐slip Ancon Fault in the possible source region of the 1906‐Mw8.6–8.8 and 1979‐Mw8.2 earthquakes, which produced devastating tsunamis.

Breaking the Black Box: Inherently Interpretable Physics‐Constrained Machine Learning With Weighted Mixed‐Effects for Imbalanced Seismic Data

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 4, December 2025.
Abstract Ground motion models (GMMs) are critical for seismic risk mitigation and infrastructure design. Machine learning (ML) is increasingly applied to GMM development due to expanding strong motion databases. However, existing ML‐based GMMs operate as “black boxes,” creating opacity that undermines confidence in engineering decisions.

Influence of Glacial Isostatic Adjustment on Intraplate Stress and Seismicity in Eastern North America in the Presence of Pre‐Existing Weak Zones

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract Eastern North America has hosted significant historical earthquakes, where seismicity clusters along tectonically inherited structures. Using the spherical finite‐element code CitcomSVE and fully 3D viscosity structure, we model the intraplate stress response to glacial isostatic adjustment (GIA) using ICE‐6G, both with and without low ...

Preparatory Phase of Major Earthquakes During Campi Flegrei Unrest (2020–2024)

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract The ongoing unrest at Campi Flegrei is posing significant challenges for hazard assessment and risk mitigation. This densely populated region has experienced more than 20,000 shallow earthquakes since 2020, driven by hydrothermal fluid accumulation beneath a mechanically strong caprock.

Mechanics and Statistics of Postseismic Shaking

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Analysis of 2 weeks of continuous post‐seismic shaking after the 2019 M7.1 Ridgecrest, CA earthquake sequence using 4 nearby borehole seismometers reveals that continuous ground motions decay as Omori's law in time and follow the Gutenberg‐Richter distribution in logarithmic amplitude.

Interplay of Loading and Adsorption Controls Elastic Deformation of Clastic and Crystalline Rocks

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract Rock elasticity varies with both mechanical loading and moisture content. Studies to date have only examined each effect independently, although moisture interactions with pore walls are likely coupled to mechanical stress. Here, we present experimental data specifically collected in sandstone and granite under simultaneous control of cyclic ...
