Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.Abstract Subsurface heterogeneity influences watershed hydrology strongly but remains difficult to characterize at catchment scales with sparse and costly field data. Geophysical surveys such as electromagnetic induction (EMI) provide local spatial subsurface images yet scaling them to watershed scales and converting EMI‐derived resistivity into ...

Vadose Zone Journal, Volume 25, Issue 1, January/February 2026.Abstract Geophysical methods provide high‐resolution spatial measurements of physical quantities sensitive to changes in soil moisture and salinity and can be used to monitor soil hydrological responses to flooding. However, extracting quantitative hydrological information from geophysical data remains challenging.

Deep Sources of Recent Volcanism in Armenia Inferred From Ambient Noise Tomography
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract We perform Rayleigh wave ambient noise tomography to investigate crustal seismic velocity structure and sources of volcanism in Armenia. Armenia, a key part of the tectonically and volcanically active Caucasus‐Anatolia region, is actively being deformed by the ongoing Arabian‐Eurasian continental collision.

Imaging of a fluid injection process using geophysical data - A didactic example [PDF]
, 2020 In many subsurface industrial applications, fluids are injected into or withdrawn from a geologic formation. It is of practical interest to quantify precisely where, when, and by how much the injected fluid alters the state of the subsurface.

In Situ Microscale Shear Failure Mechanism in Hot Dry Rock Under Thermal Cycling
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 1, January 2026.Abstract Induced shear failure is key for enhancing hot dry rock (HDR) resource exploitation, aiming to creating an extensive fracture network. Although the macroscopic shear behavior of HDR has been extensively investigated, its microscopic shear failure mechanisms remain unclear.

Vector‐Based and Machine Learning Approaches for Pore Network Parameters Analysis
Geophysical Prospecting, Volume 74, Issue 1, January 2026.ABSTRACT Accurate characterization of pore structures in carbonate rocks is critical for evaluating fluid flow and storage capacity in subsurface reservoirs, a key concern in geophysical exploration and reservoir engineering. This study proposes a hybrid digital rock physics workflow that integrates deep learning–based segmentation, vectorial geometric

Geophysical investigation of the Pb-Zn deposit of Lontzen-Poppelsberg, Belgium [PDF]
, 2018 The drillhole information from the Lontzen-Poppelsberg site has demonstrated three orebodies and has allowed the estimation of the extension of the lodes, their dip, and the location at the ground surface.
