Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Swarms are microearthquake clusters governed by aseismic deformation, fluid migration, and stress changes, but the underlying mechanisms for their recurrence remain elusive. In 2008, abundant swarms were observed on the westernmost Gofar transform fault.

Penetration of Warm Slabs Across the 660 km Boundary: The Potential Role of Hydrous Stishovite
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract We investigate the phase boundary of hydrous/anhydrous post‐spinel transition at conditions relevant to the 660 km boundary. For the hydrous ringwoodite decomposition, the slope is found to range from negative to positive values depending on the distribution of water between the final products, namely, bridgmanite, periclase (mostly anhydrous)

Regional‐to‐Global Tectonic and Trench‐Morphology Effects of Oceanic Plateau Subduction
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract Regional geodynamic modeling has shown that oceanic plateau subduction can modify the slab behavior. However, few studies have explored these interactions beyond 100 Myr in 3‐D spherical models. Using 3‐D spherical mantle convection models with self‐consistent plate‐like behavior, we investigate how the geometry and rheological properties of ...

A Shape Optimization Approach for Inferring Sources of Volcano Ground Deformation
Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract One of the main goals of volcano geodesy is to improve the understanding of how an increase in pressure related to magma accumulation causes ground deformation in order to evaluate volcanic unrest. The inversion methods used for this purpose rely on a parametrization of the shape of the crustal volume in which pressure changes due to magma ...

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.Abstract The Yingxiu–Beichuan Fault Zone (YBFZ), located in the Longmen Shan Thrust Belt (LSTB) on the eastern Tibetan Plateau, is highly seismically active. However, direct evidence of large earthquakes at depth is scarce. Here, we present rock magnetic, microstructural, and geochemical analyses of four fault zones from the Wenchuan Earthquake Fault ...
