Trench‐Breaching Rupture of the 2025 Mw 8.8 Kamchatka Earthquake and How It Repeats the 1952 Event

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The 29 July 2025 Mw 8.8 Kamchatka earthquake generated a trans‐Pacific tsunami. The hypocenter was nearly at the same location as the 1952 great earthquake (Mw 8.8–9.0). Determining whether the 2025 rupture reached the trench and how it relates to the 1952 event is crucial for understanding slip behavior along the Kamchatka subduction zone. We

A Novel Technique for Extracting the Tidal Magnetic Field: Methodology and Application to a Pre‐Processed Dataset of CSES and Swarm

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The oceanic tidal magnetic field, mainly driven by the circular orbital motion of the Moon, is an essential part of the time‐varying geomagnetic field. The previously adopted time‐harmonic (TH) base worked well in fitting the primary M2 ${M}_{2}$ tidal field, but extracting the other weaker modes like the N2 ${N}_{2}$ was difficult with only a

The Slip Distributions of the 1952 and 2025 Kamchatka Earthquakes From Tsunami Waveforms Recorded Around the Pacific Ocean

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract The July 2025 Kamchatka earthquake (Mw 8.8) generated Pacific‐wide tsunamis. Inversion of 40 DART bottom pressure records revealed a large (∼9 m) slip at 200–400 km southwest of the epicenter. This model reproduces the local geodetic data, and is similar to other finite fault models based on teleseismic and geodetic data. Inversion of the tide

Ostwald Ripening in Underground Gas Storage

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Underground gas storage supports the energy transition, enabling long‐term CO2 ${\text{CO}}_{2}$ sequestration and seasonal H2 ${\mathrm{H}}_{2}$ storage. A key process shaping the fate of injected gases is Ostwald ripening—the curvature‐driven mass transfer between trapped ganglia—yet its behavior in confined porous structures remains poorly ...

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

open access: yesGeophysical 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.

Comparative Analysis of Seismicity Across Three Depth‐Dependent Slip Regimes in the Japan Trench Subduction Zone

open access: yesGeophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Understanding the cause of spatial variations in seismicity is crucial for comprehending the physics governing earthquake activity. Off Iwate, in the northern Japan Trench subduction zone, the plate boundary can be divided into three distinct zones based on depth‐dependent slip regimes: the slow earthquake, asperity, and stable creeping zones.
