Cessation of Nearby Low‐Frequency Earthquake Activity Following the December 2024 Mw 7.0 Mendocino Earthquake: The Likely Role of Pore Pressure Reductions

open access: yesGeophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Earthquakes affect surrounding fault systems through multiple mechanisms. Here, we examine a rare cessation of activity in 27 families of low‐frequency earthquakes (LFEs) that likely reflect fault creep at the southern edge of Cascadia subduction, near the Mendocino triple junction.

Shallow Poroelastic Hydrothermal Deformation at Changbaishan Volcano Before the 2020 Unrest Revealed by Sentinel‐1 InSAR Time Series

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Ground deformation of dormant volcanoes provides critical insights into subsurface processes and potential hazards. Here we present Sentinel‐1 Interferometric Synthetic Aperture Radar (InSAR) time series (2015–2020) for Changbaishan volcano, the largest intraplate volcanic system in East Asia. We detect persistent subsidence of up to 3.5 mm/yr

An Innovative Approach for Estimating Coseismic Surface Uplifts Using Ionospheric Observations From Remote GNSS Stations: First Application for the 2025 Myanmar Earthquake

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The Mw 7.7 Myanmar earthquake on 28 March 2025 ruptured ∼480 km of the Sagaing Fault. Its fault slip distribution remains poorly constrained by three‐dimensional surface displacement data due to sparse GNSS‐coverage near the fault. Satellite‐based synthetic aperture radars capture meters of right‐lateral displacements but isolating vertical ...

Rare Synchronization Among Recurring Earthquakes

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Earthquakes are notoriously irregular, yet occasionally neighboring faults rupture in close succession, repeatedly, as if synchronized. Over successive cycles, differences in recurrence intervals, overall irregularity and external stressors should all drive neighboring faults out of phase.

State of Stress in Subduction Zone Forearcs: Influence of the Mantle Wedge Corner and Serpentinization

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract We investigate the role of the elasticity and density of the forearc mantle wedge corner on the stress distribution in the forearc region of subduction zones, using numerical quasi‐2D lithospheric deformation models for the Cascadia, Nankai, NE Japan, and Costa Rica subduction zones. We incorporate the forearc mantle wedge corner as an elastic

In Situ Observation of Pressure‐Enhanced Hydrous–Anhydrous Solid Solution in Lower‐Mantle SiO2–AlOOH Phases

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Water plays a critical role in Earth's mantle dynamics and evolution, yet lower‐mantle storage mechanisms remain debated. δ‐AlOOH and SiO2 phases have been independently proposed as high‐pressure water hosts. Here, we conducted in situ synchrotron X‐ray diffraction experiments with a multi‐anvil apparatus and sintered diamond anvils to ...

Quantifying Land–Sea Connectivity Through Remotely Sensed River Plumes

open access: yesGeophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Coastal ecosystems are highly influenced by riverine freshwater inputs, but the nature of these influences is dynamic and hard to characterize. Here we present a method that leverages remote sensing data of river plumes to quantify land–sea connectivity.
