Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Seismic ruptures that extend over kilometers along faults originate in shear zones only millimeters thick. We present a hybrid numerical framework coupling the spectral boundary integral method (SBIM) for the poroelastic bulk with a staggered‐grid finite difference method (FDM) for the fault gouge.

Ground motion scenarios for the 1997 Colfiorito, central Italy, earthquake
Annals of Geophysics, 2008 In this paper we report the results of several investigations aimed at evaluating ground motion scenarios for the September 26th, 1997 Colfiorito earthquake (Mw 6.0, 09:40 UTC).

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Understanding fault‐zone permeability is crucial in model‐based assessment of fluid migration, earthquake nucleation, and hydrothermal or hydrocarbon systems. Vertical seismic profiling (VSP) often captures Stoneley (tube) waves generated by fluid‐formation coupling in and around a borehole.

Stress and Strain in Magma‐Mush Reservoirs: Implications for Reservoir Failure and Magma Propagation
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Investigating the mechanical stability and failure of magma reservoirs following magma supply is critical for volcanic hazard assessment. While magma reservoirs were traditionally modeled as melt‐filled cavities, they are now more often described as crystal mushes where melt flows and is stored in porous networks.

The Influence of Grain Crushing and Pore Collapse on the Formation of Faults
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract During an earthquake, slip occurs in a localized shear zone that features a heavily granulated fault core that can be characterized as a shear band. We study the formation of this fault core in a granular rock such as sandstone by developing a model of crushable granular media within the framework of Breakage Mechanics. This model accounts for

Dynamic Earthquake Source Inversion With Generative Adversarial Network Priors
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract Dynamic earthquake source inversion consists of inferring frictional parameters and initial stress on a fault consistent with recorded seismological and geodetic data and with dynamic earthquake rupture models. In a Bayesian inversion approach, the nonlinear relationship between model parameters and data requires a computationally demanding ...

Fault Roughness Controls Seismicity Front Migration During Fluid Injection
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.Abstract The increasing occurrence of injection‐induced earthquakes has raised public concern and highlighted the importance of understanding subsurface processes and mechanisms to assess induced seismic hazards and risks. We develop a simple physics‐based model to investigate how fault roughness controls the migration of seismicity during fluid ...

Tectonics, Volume 45, Issue 3, March 2026.Abstract The strength of the intracontinental lower crust exerts a primary control on regional‐scale deformation during continent‐continent collision. Because of the nominally anhydrous nature of much of the intracontinental lower crust, it is generally considered to be more viscous than lower crust in hydrated tectonic margins.
