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)

Spatiotemporal Variations in the Interplate Slip Rate Around Kodiak Island, Alaska

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Monitoring spatiotemporal variations in the interplate slip rate during the interseismic period, such as transient strain release by slow slip events (SSEs), is crucial for characterizing the physical properties of faults. We analyze 10 years of Global Navigation Satellite System (GNSS) data in the region of Kodiak Island, Alaska.

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 ...

Crustal Heat Flow Drives the Earthquake Magnitude Distribution

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Earthquake magnitude‐frequency distributions exhibit significant space‐time variations, which can provide critical insights into the physical processes driving seismicity. Understanding these variations is crucial for assessing seismic hazards and uncovering the physical processes driving earthquakes.

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 ...
