Al2O3 in Anorthositic Slabs: A New Perspective on LLSVPs and Seismic Velocity Variations

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Aluminum is a key component of crustal and mantle minerals, influencing melting and geochemical evolution within the Earth. Al2O3 exists as corundum at the surface and in upper mantle conditions, but transforms into high‐pressure phases like Rh2O3(II) at lower mantle depths, enabling stability over a wide pressure range.

The Role of Fluids in Fault Mechanics: A 16‐Year Analysis of the Irpinia Seismicity (Southern Italy)

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Fluids in the crust influence earthquake nucleation by affecting fault strength and rupture dynamics, but direct observations at seismogenic depths are rare. We study the Irpinia Fault System in Southern Italy, site of the 1980 M 6.9 earthquake, to understand how fluid overpressure, fault orientation, and regional stress control earthquake ...

Fault Kinematic Controls on the Spatio‐Temporal Proximity of the 2023 Mw 7.8‐7.7 Türkiye Earthquakes

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The mechanism governing the spatio‐temporal proximity of the 2023 Mw 7.8‐7.7 Türkiye earthquakes remains enigmatic. Here, we used dense geodetic observations integrated with dual‐fault screw dislocation, Euler‐vector‐constrained block, and strain‐rate models to investigate the interseismic kinematics and pre‐stress state of the East Anatolian ...

A >300 Myr Long‐Lived Topographic Highland Along the Northern North China Craton Margin Driven by Multistage Continental Convergence

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Topographic highlands commonly develop along convergent plate boundaries through long‐term processes such as subduction and continental collision. However, the pre‐Cenozoic mountain‐building history of deep‐time orogenic systems in northeastern Pangaea remains poorly constrained due to later tectonic overprinting and denudation.

The Detection of Transient Subduction Zone Interface Properties Using Teleseismic Data

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The physical properties of subduction zone interfaces govern the transition between stable aseismic slip, episodic slow slip events (SSEs), and large earthquakes. Ultraslow velocity layers (USVLs) along the megathrust are commonly interpreted as indicators of elevated pore‐fluid pressures that promote slow slip, but their temporal variability ...
