Simulator‐Based Bayesian Inference of Enhanced Geothermal Reservoir Properties
Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Inversions of dynamic multi‐scale multi‐physics subsurface system properties rely on the effective sampling of high‐dimensional parameter spaces and are thus notoriously difficult to perform. The associated models are defined by complex nonlinear relationships with potentially stochastic components, which lead to analytically intractable ...

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract We propose a variational autoencoder framework to directly assess uncertainties in subsurface models produced by single‐ and multiparameter full waveform inversion (FWI). The new method does not require pretraining on labeled data, thus it significantly reduces computational cost and storage requirements.

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.Abstract Full‐waveform inversion (FWI) relies on sequential‐source (SQ) workflows for high imaging precision, while simultaneous‐source (SML) encoding drastically accelerates computation but introduces irreversible wavenumber discontinuity artifacts in hybrid‐domain implementations.

Geophysical Prospecting, Volume 74, Issue 8, October 2026.ABSTRACT We developed a new experimental setup for measuring and modelling stress‐induced anisotropy and nonlinearity in cylindrical rock samples. Multidirectional ultrasonic velocity measurements were conducted under laboratory conditions and during triaxial‐stress testing to capture dynamic rock properties. This is done by placing endcap transducers (

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna Basin, preceding a regionally significant intraplate earthquake sequence ...

Segmented Moho Uplift and Implications for Magmatic Underplating Beneath the Datong Basin
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Understanding how the deep crust responds to coupled tectonic and magmatic processes is essential for deciphering intracontinental rifting. We apply high‐resolution passive‐source reverse time migration to teleseismic P‐wave receiver functions recorded by a dense seismic array to image the Moho beneath the Datong Basin. Our observations reveal

Enhancing multiparameter elastic full-waveform inversion with a Siamese network
Using the proper data misfit measure within full-waveform inversion (FWI) is crucial for achieving robust inversion performance. This choice is complicated by the fact that our simulations are often based on simplified assumptions of the earth admitting ...

Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract The Pamir, located at the northwestern margin of the Tibetan Plateau, is undergoing E–W extension within its interior, accommodated by micro‐block motions along major fault systems; however, the mechanisms governing this modern block kinematics remain elusive.

Source‐Unbiased Subsurface Monitoring With Seismic Noise
Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract This study addresses a key limitation of seismic noise interferometry for subsurface monitoring: the impact of non‐stationary sources on seismic velocity change estimates. Conventional methods rely on time‐period references, which can inherit source‐related effects when source conditions vary, biasing the estimated velocity changes.
