Structural Heterogeneity Shapes Segmentation of Megathrust Earthquakes and Volcanism in Central America

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The mechanisms underlying the patchy distribution of forearc megathrust earthquakes and arc volcanoes in subduction zones remain poorly understood. Here we present a high‐resolution seismic tomographic model of the Central American subduction zone, derived from a joint inversion of local body‐wave and teleseismic Rayleigh‐wave data.

Hydrogen‐Bond Symmetrization in Hydrous Aluminous Silica Enhances Deep‐Mantle Water Cycle

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract (Al, H)‐bearing CaCl2‐type SiO2 serves as a key water carrier in Earth's deep‐water cycle. Evolution of hydrogen‐bond symmetrization in this phase was measured up to 62 GPa and 800 K by synchrotron infrared and Raman spectroscopy, and X‐ray diffraction.

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.

The Role of Tectonic Inheritance in Active Rift Seismicity and Magmatism: Constraints From 3‐D Gravity Inversion and D‐InSAR Modeling of the 2025 Fentale Swarm, Ethiopia

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The role of inherited lithospheric structures in active rift seismicity and magma intrusion remains a key uncertainty in continental breakup dynamics. We investigate the January 2025 Northern Main Ethiopian Rift swarm using constrained 3‐D gravity inversion and D‐InSAR observations to characterize crustal architecture, seismicity, and active ...

Aseismic Slip Along the Evaporite‐Rich Strike‐Slip Katouna‐Stamna Fault in Greece

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Aseismic slip has been observed on many active faults globally, but its controlling mechanisms remain unclear. This study focuses on the NW‐striking, left‐lateral Katouna‐Stamna Fault in Western Greece. We use InSAR surface deformation measurements to confirm the presence of aseismic slip and compare this behavior with structural evidence from

Unexpected Global Prevalence of Mesopelagic Particle Layers Detected by BGC‐Argo Floats

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Particulate organic carbon transported to the deep ocean forms a critical component of the Earth's carbon cycle. The concentration of these particles is generally parameterized in models to decrease continuously with depth, but isolated layers of small particles (≤ ${\le} $20 μm ${\upmu }\mathrm{m}$) observed within the mesopelagic challenge ...

Fluid Injection Triggers Large‐Scale Slow‐Slip Activation of the Rocky Mountain Fold and Thrust Belt

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Using interferometric synthetic aperture radar (InSAR) we show that hydraulic fracturing treatments near the subsurface deformation limit of the Rocky Mountain Fold and Thrust Belt produced 12 intraplate, aseismic, slow‐slip events with magnitudes Mw ${M}_{w}$ 4.71–5.06 at 1,640–2,410 m depths.

Fault‐Controlled Plumbing System Beneath Lipari Volcanic Island Revealed by Seismic Matrix Imaging

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Lipari Island hosts an active magmatic–hydrothermal system, but its deep plumbing architecture remains poorly resolved due to strong seismic scattering. We apply passive seismic matrix imaging to public vertical‐component cross‐correlation functions from the dense 2018 Lipari nodal array, recovering relative‐reflectivity structures to ∼10 km ...
