Near‐Source Ground Motion From Normal Faults: Insights From the Physics‐Based Numerical Simulations of the 1980 Irpinia Earthquake, Southern Italy

Earthquake Spectra, Volume 42, Issue 2, May 2026.
In this paper, the physics‐based numerical simulation of the strongest instrumental earthquake in the recent seismic history of Italy, i.e., the Nov 23, 1980 Irpinia earthquake in Southern Italy, with magnitude MW 6.8, is presented and discussed. A 3D spectral element model covering an extended region (147 × 110 km2) was constructed, with a frequency ...

Fine‐Scale Segmentation and Spatiotemporal Variability of the 2010 Mw 8.8 Maule Aftershock Sequence Revealed by a Deep‐Learning‐Based Earthquake Catalog

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract We re‐examine the aftershock sequence of the Mw 8.8 Maule earthquake in south‐central Chile to understand how seismicity, magnitude‐frequency distribution, and fault structure vary along the rupture zone. Using the International Maule Aftershock Deployment (IMAD) data set, we analyze 10 months of continuous data from approximately 156 ...

Strain‐based modeling and analysis for rock blasting and geomechanics applications

Deep Underground Science and Engineering, Volume 5, Issue 1, Page 28-42, March 2026.
This paper introduces a novel strain‐based modeling approach for blasting and geomechanical applications, using measurable variables like particle velocity, strain, and displacement. By bypassing complex constitutive relations, strain‐based models capture critical blasting trends and full‐blast design parameters with minimal calibration.

Experimental Hypervelocity Dust Impacts in Olivine—Multiscale Insights Into Microcrater Shock and Melting Effects From Coordinated SEM/TEM Observations

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The flux of solar system meteoroids is dominated by objects less than 1 mm in diameter whose impact effects play a major role in the space weathering of airless body surfaces. These effects remain poorly characterized with respect to their dependence on the range of impact speeds for meteoroids across the inner solar system.

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.
