Slab Dehydration Linked to Great Earthquake Rupture Barriers Along the Alaska Peninsula

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The amount of water entering subduction zones and how it is stored within the slab is debated. This limits our understanding of where subducted fluids are released and therefore how pore pressure influences slip behavior along megathrusts. Here we present 3‐D compressional and shear‐wave velocity models, and their ratio Vp/Vs, of the Alaska ...

Phanerozoic Onset of Massive Continental Weathering

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Continental weathering acts as a nexus of global biogeochemical cycles yet its long‐term evolution remains unclear. Here we show that continental weathering may not have operated on a massive scale until the early Paleozoic based on a large‐number data compilation of mudstone geochemistry.

Petrogenetic and geochemical characteristics of some auriferous granitoids in the Kumasi Basin, Ghana: Implications for geodynamic settings and controls of orogenic gold mineralization in the Edikan Gold Mine

Deep Underground Science and Engineering, Volume 4, Issue 3, Page 406-421, September 2025.
The Fobinso granitoids are granodiorites, while the Esuajah granitoids are granites based on their mineralogical composition. The granitoids are generally enriched in LILE and LREE than HFSE, MREE, and HREE, indicating mixing with crustal sources during their evolution.

Integration of Physics‐Based and Data‐Driven Approaches for Landslide Susceptibility Assessment

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 13, Page 3060-3097, September 2025.
ABSTRACT Rainfall‐triggered landslides pose a significant threat to communities and infrastructure around the world. Various data‐driven and machine learning (ML) based algorithms have been applied to assess landslide susceptibility. However, purely data‐driven methods are affected by issues such as uncertainty in the selection of landslide ...
