The Role of Normal Stress and Shear Stress Heterogeneity in the Inferred Depth‐Independence of Stress Drop

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Earthquake stress drops are inferred to be independent of source depth, contradicting linear scaling predictions for earthquakes as frictional stick‐slip instabilities that assume increasing fault normal stress due to overburden. Here, we examine the scaling between averaged stress drops and increasing normal stress for simulated earthquake ...

Sound Velocities of FeO‐Bearing Ringwoodite and Majorite: Implication for Martian Mantle Seismic Profiles

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Compressional and shear wave velocities (Vp, Vs) of candidate Martian deep‐mantle minerals, FeO‐rich ringwoodite ((Mg0.66Fe0.34)2SiO4) and majorite (Mg0.75Fe0.10Al0.26Ca0.07Si0.84O3), were measured up to 25 GPa and 700 K using Brillouin light scattering coupled with externally‐heated diamond anvil cells.

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

open access: yesGeophysical 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.

The Magnetic Signature of Stress in Rocks

open access: yesGeophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Magnetic signatures preserved in rocks have long provided insight into Earth's evolution, revealing processes from plate tectonics to the habitability of Earth. While large impacts are known to impose extreme stresses (>1 GPa) and heat that fundamentally alters magnetic records, lower stresses typical of earthquakes have been considered ...

Salt Precipitation‐Driven Rock Failure Mode Transition During Geological CO2 Sequestration

open access: yesGeophysical 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 ...
