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

Tide‐Modulated Ocean‐to‐Earth Energy Conversion Quantified With Coastal Fiber Sensing
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Quantifying how incident ocean waves transfer energy into seismic surface waves along the nearshore is essential for understanding coastal hazards and Earth–ocean coupling, yet time‐resolved in situ estimates have been scarce. Here we use a beach‐deployed distributed acoustic sensing array co‐located with an ocean‐bottom node to directly ...

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.

Monitoring rock freezing and thawing by novel geoelectrical and acoustic techniques [PDF]
, 2016 Automated monitoring of freeze-thaw cycles and fracture propagation in mountain rockwalls is 23 needed to provide early warning about rockfall hazards. Conventional geoelectrical methods 24 such as electrical resistivity tomography (ERT) are limited by ...

Salt Precipitation‐Driven Rock Failure Mode Transition During Geological CO2 Sequestration
Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.Abstract Salt precipitation has emerged as a critical factor affecting injectivity, reservoir stability, and the potential to trigger near‐wellbore microseismic activity during geological CO2 sequestration. While previous studies have primarily focused on the brine acidification induced by CO2 injection, triggering geochemical reactions in carbonate ...

A Bayesian method for microseismic source inversion [PDF]
, 2016 Earthquake source inversion is highly dependent on location determination and velocity models. Uncertainties in both the model parameters and the observations need to be rigorously incorporated into an inversion approach.
