Poromechanical and Crack Evolution of Olivine‐Rich Rock During Serpentinization

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Serpentinization alters the strength, fracture behavior, and rheology of ultramafic rocks, yet the coupled evolution of mineral reactions, cracking, and mechanical softening remains poorly constrained. We experimentally simulated serpentinization in dunite at 220°C and 15 MPa for 14 and 30 days and compared the reacted specimens with dry heat ...

Seismic Precursors to the Blatten, Switzerland Landslide Revealed by Unsupervised Machine Learning

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The transition from stable to unstable states in geological systems, such as landslides and fault zones, remains poorly understood. Seismic precursors and foreshocks related to the transition, if present, are often difficult to observe, and their interpretation remains challenging.

First Detection of the Two‐Dimensional Vertical Propagation of Traveling Ionospheric Disturbances Associated With Atmospheric Gravity Waves in the Martian Ionosphere

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We report the detection of a traveling ionospheric disturbance (TID) captured by the Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) Active Ionospheric Sounding (AIS) instrument aboard the Mars Express spacecraft at 150–250 km altitude.

Dynamic Coupling Between Faulting, Rifting and Magmatism During 2021‐2025 Unrest on Reykjanes Peninsula, Iceland

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Interactions among faulting, earthquakes, and eruptions are fundamental to plate tectonics and hazard forecasting yet rarely observed along mid‐ocean ridges. On Iceland's Reykjanes Peninsula, seismotectonic–volcanic unrest resumed after nearly 800‐year hiatus, providing an opportunity to observe these interactions during 2021–2025 activity. By

Deformation of δ‐AlOOH and Its Solid Solution With Phase H as a Potential Source of Intra‐Slab Seismic Anisotropy in the Mid‐Mantle

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Seismic anisotropy is widely observed near subduction zones in the mantle transition zone and uppermost lower mantle, particularly along the western Pacific rim and tracks slabs geometries, implying an additional slab‐related source. Hydrous phases such as δ‐AlOOH and phase H (MgSiO4H2), which form a solid solution (δ‐H) and are stable in cool,
