Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract The mantle transition zone (MTZ; ∼410–660 km depth) is a major reservoir of water and mid‐ocean ridge basalt (MORB)‐like materials, yet how composition and hydration regulate its physical stability remains unclear. Using geodynamical modeling, we examine the joint effect of water content and dense MORB fraction on the density, viscosity, and ...

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Fault‐slip reversals indicate transient stress changes and may illuminate earthquake preparation processes. Here we present high‐resolution observations of sub‐millimetric creep and slip reversals on the Altaquelle Fault, a Quaternary normal fault in the southern Vienna Basin, preceding a regionally significant intraplate earthquake sequence ...

Segmented Moho Uplift and Implications for Magmatic Underplating Beneath the Datong Basin
Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.Abstract Understanding how the deep crust responds to coupled tectonic and magmatic processes is essential for deciphering intracontinental rifting. We apply high‐resolution passive‐source reverse time migration to teleseismic P‐wave receiver functions recorded by a dense seismic array to image the Moho beneath the Datong Basin. Our observations reveal

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.

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 ...

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.Abstract The Pamir, located at the northwestern margin of the Tibetan Plateau, is undergoing E–W extension within its interior, accommodated by micro‐block motions along major fault systems; however, the mechanisms governing this modern block kinematics remain elusive.

Reviews of Geophysics, Volume 64, Issue 3, September 2026.Abstract Understanding the coastal zone of the Antarctic Ice Sheet (AIS), where it interacts with the Southern Ocean and warmer air masses, is crucial for predicting Antarctica's influence on the global climate and sea level. This region has multiple tipping mechanisms that could trigger large, rapid, and potentially irreversible changes in the AIS ...

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract The 2024 Mw 7.5 Noto Peninsula earthquake provided an opportunity to investigate postseismic deformation in a tectonically complex back‐arc region in central Japan, where Miocene normal faults are reactivated under present‐day compression.

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract In July 2021, an episode of uplift started at Askja caldera, Iceland, following over 50 years of subsidence. The initial inflation rate was approximately 700mm/yr $700\hspace*{.5em}\mathrm{m}\mathrm{m}/\mathrm{y}\mathrm{r}$, declining to 350mm/yr $350\hspace*{.5em}\mathrm{m}\mathrm{m}/\mathrm{y}\mathrm{r}$ within 1 month.

Imaging the Alpine Collision With Seismic Radial Anisotropy
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.Abstract The Alpine region and the adjacent Northern Apennines (NA) and Northern Dinarides record the complex tectonic evolution associated with the collision between the Eurasian and Adriatic plates. We combine Rayleigh and Love surface waves from ambient noise and earthquake data recorded at over 3,300 seismic stations to construct a high‐resolution ...
