The von Neumann Stability Analysis of the Fixed‐Stress Schemes in Poroelastodynamics

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 4, Page 1939-1951, March 2026.
ABSTRACT We investigate splitting schemes based on the fixed‐stress sequential approach for poroelastodynamic problems. To assess numerical stability, we perform the von Neumann stability analysis on several fixed‐stress schemes for poroelastodynamics, including staggered, stabilized, and iterative methods. Our analysis reveals that while the staggered

Induced Earthquakes in the Southern Delaware Basin, Texas, Are Bound by a Geomechanically Controlled Maximum Magnitude

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract In this paper we document the first example‐the southern Delaware Basin‐where widespread induced triggered (as opposed to “driven”) seismicity across a large area exhibits a maximum magnitude truncation. The most likely cause of this truncation is that although the shallow faults in this area are many km in length, they are structurally ...

4D Electrical Resistivity Imaging of Stress Perturbations Induced During High‐Pressure Shear Stimulation Tests

Geophysical Research Letters
Fluid flow through fractured media is typically governed by the distribution of fracture apertures, which are in turn governed by stress. Consequently, understanding subsurface stress is critical for understanding and predicting subsurface fluid flow ...

Cycled Fluid Injection Limits Maximum Earthquake Size by Controlling the Cadence of Seismic Moment Release

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Controlling fluid injection is widely considered a key to limiting the size of injection‐induced seismicity, yet whether and how it limits earthquake size remains debated. We perform injection‐reactivation experiments on critically stressed faults to test how different injection strategies shape slip and seismic moment release.

Stress and Rock Failure Near Salt Bodies: Insights From Field Observations, Kinematic Modeling, and Mechanical Analysis Near Arches National Park, Paradox Basin, Utah

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Salt's inherent weakness and capacity for ductile deformation create significant mechanical contrasts that locally perturb the stress field in surrounding rocks, often leading to deviations from regional tectonic stresses. Variations in local stress are a critical factor for wellbore stability, seal integrity, and fluid flow in subsurface ...

Inversion of Short‐Period Seismic Signals as a Tool to Understand Small‐Volume Rockslide Mechanics: The Case Study of the 26 January 2023, Lorgino (Crevoladossola, NW Italy) Rockslide

Earth and Space Science, Volume 13, Issue 2, February 2026.
Abstract A small‐volume 6,000 m3 rockslide struck the Lorgino hamlet of Crevoladossola (NW Italy) just before 23:00 UTC on 26 January 2023, at the boundary of a nearby marble quarry. The rockslide severely damaged the mining infrastructure and halted operations for months, fortunately without causing injuries or casualties.
