Surrogate‐Assisted Bayesian Inference of Fracture Network Parameters From Elastic Waves: A Sensitivity‐Guided Approach

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract We develop a sensitivity‐guided, surrogate‐assisted Bayesian framework to infer fracture network parameters from elastic waves. Synthetic fracture networks characterized by power‐law length exponent a $a$, fracture density d $d$, and percolation parameter p $p$ are constructed.

Seismic Insights Into the Role of Rockfall in Rockslide Destruction Processes

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract The dynamic link between rockslide failure and rockfall activity remains elusive, primarily due to the challenge of detecting weak signals amidst high noise. We propose a seismic attribute guided deep learning framework that formulates rockfall detection as a time‐series segmentation task, facilitating the precise extraction of rockfall events

Cyclic Thermal Shock‐Induced Permeability Enhancement in Tight Lithologies: Microstructural Controls and Elastic‐Wave Monitoring

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Enhanced geothermal systems rely on increasing permeability and pore surface area in rock. Cyclic thermal shocking can achieve both by inducing thermal cracks through repeated rapid cooling. Laboratory experiments subjected micritic limestone, granodiorite, and trachybasalt to up to 10 thermal shock cycles, while tracking crack evolution ...

Distributed Acoustic Sensing (DAS) Waveforms: Effects of Source Signature, Geometry, and Attenuation

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Distributed acoustic sensing (DAS) records strain integrated over a finite gauge length depending on incidence angle, frequency, material velocities, fiber curvature, and gauge length. The DAS responses to a monofrequency plane wave of these are well understood.

Active Hydrothermal Hydrogen Emissions in Continental Collision Settings: Insights From the Southeastern Tibetan Plateau

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract Natural hydrogen (H2) is a promising clean energy resource and a significant component of geothermal gases, yet its origins and release mechanisms remain poorly constrained. Here, we present geochemical and isotopic data (CO2, N2, Ar, H2, He, CH4, 3He/4He, δ13C‐CO2, and δ13C‐CH4) for hydrothermal gases from the Changning–Menglian suture (CMS),

The Role of Crustal Rheology and Mantle Fluids on the Interseismic Behavior of the Main Marmara Fault

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Faults can release tectonic loading either in the form of seismic events or via aseismic creep. The Main Marmara Fault (MMF) in the Sea of Marmara exhibits both locked and creeping behavior and poses a significant hazard to the megacity of Istanbul.

Stress Drop and Seismic Efficiency Distributions Over the Adriatic Indenter (European Southeastern Alps)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Seismic source parameters, such as seismic moment, stress drop, and radiated energy, are key to understanding earthquake dynamics and rupture processes. In this study, we apply a non‐parametric Generalized Inversion Technique (GIT) to characterize the source properties of 735 earthquakes (local magnitudes 1.65 ≤ ML ≤ 4.55) recorded between ...
