Model‐Predicted Shear‐Wave‐Splitting Parameters in NE Japan: Comparison With Observations

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract We model olivine crystal preferred orientation (CPO) and shear wave splitting (SWS) in the mantle wedge, using the results of a 3‐D numerical thermomechanical model for the NE Japan subduction zone. The model predicts a quasi‐2‐D trench‐normal (E‐W) mantle wedge flow pattern beneath Tohoku, given the trench‐normal subduction, but a more ...

A Spatio‐Temporal Neural Kernel Function Model for Earthquake Clustering: Bridging ETAS and Neural Point Processes

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Modeling earthquake clustering in space and time is central to understanding seismicity patterns and improving forecasting. The Epidemic‐Type Aftershock Sequence (ETAS) model, grounded in the Hawkes process, has long been the standard approach for describing aftershock triggering through fixed, empirically defined kernel functions.

Diffusion Priors Enhanced Velocity Model Building From Time‐Lag Images Using a Neural Operator

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Velocity model building (VMB) serves as a crucial component for achieving high precision subsurface imaging. However, conventional VMB methods are often computationally expensive and time consuming. In recent years, with the rapid advancement of deep learning, particularly the success of generative models and neural operators (NOs), deep ...

ECOMAN: an open-source package for geodynamic and seismological modelling of mechanical anisotropy [PDF]

Solid Earth
Mechanical anisotropy related to rock fabrics is a proxy for constraining the Earth's deformation patterns. However, the forward and inverse modelling of mechanical anisotropy in 3D large-scale domains has been traditionally hampered by the intensive ...

Full‐Waveform Seismic Tomography of the Upper Mantle Beneath the Arabia‐Eurasia Collision Zone

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Despite being one of the most recent major orogenic events, the timing of the Arabia‐Eurasia collision is still debated. Much of the discrepancy arises due to uncertainties over the amount of continental subduction of the Arabian passive margin and the timing of a hard collision of cratonic Arabian lithosphere with Eurasia.

Episodic Change, Quiescence, and Recovery of Earth's Inner Core Surface

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract While a consensus has emerged that the hypothesis of inner core differential rotation cannot provide a consistent explanation for the seismic data, it remains debated whether the seismic data indicate a concurrence of a temporal change of inner core surface with an inner core differential rotation or the temporal change of inner core surface ...
