Modulation of Slow Slip Event Characteristics Throughout the Costa Rica Subduction Zone Earthquake Cycle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Slow slip events (SSEs) represent an aseismic transient slip mode that repeats quasi‐periodically, near or partially overlapping with the megathrust earthquake zone. However, the process of stress interaction between SSEs and earthquake zones is not clearly understood.

Assimilation of 5G Base Station Networks as Ultra‐Dense Atmospheric Sensors for Advancing Heavy Rainfall Prediction

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract The zenith total delay (ZTD) retrieved from 5G communication base stations represents a novel observation source for numerical weather prediction (NWP), leveraging the extensive global deployment of 5G infrastructure. In this study, the direct assimilation of 5G‐ZTD observations into a high‐resolution NWP system was accomplished for the first ...

Correcting Unwrapping Errors Toward Reliable Rock Glacier Velocity From InSAR Time Series

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Rock Glacier Velocity is an Essential Climate Variable Permafrost Quantity, providing a quantifiable indicator of mountain permafrost evolution. Despite its wide usage, multi‐temporal InSAR often substantially underestimates rock glacier velocities compared to ground‐based measurements, limiting its reliability.

Long‐Term Increase in Equatorial Rayleigh‐Taylor Instability: Synergistic Effects of Greenhouse Gas Cooling and Geomagnetic Field Secular Variation

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Equatorial plasma bubbles (EPBs) are ionospheric irregularities generated by Rayleigh–Taylor instability (RTI) that disrupt satellite communications. We quantify secular change of RTI growth rates and isolate underlying drivers using WACCM‐X simulations.

Decadal Creep Acceleration on the Northern Japan Trench Driven by Erosion of Heterogeneously Locked Asperities

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Geodetic and seismic observations before the 2011 Mw 9.0 Tohoku‐oki earthquake indicate decadal‐scale acceleration of aseismic slip along the northern Japan Trench, but the mechanism remains debated. We show that this transient can be explained by creep‐front propagation that progressively erodes heterogeneously locked asperities.
