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.

Observation of Daily Flood Hazard During the SWOT Cal/Val Orbit

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Flood peaks can develop and recede within a day, making them difficult to capture with satellites with multi‐day revisit intervals. Here, we exploit daily observations during the Calibration and Validation phase of the SWOT mission to examine a short‐lived flood in May 2023 along the Du Gouffre River in Canada. Despite channel widths below 100

Investigating Postseismic Creep in the Laboratory: Testing Dislocation‐Based Models for Transient Creep in the Upper Mantle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Studies of postseismic creep often infer a strong reduction in upper‐mantle viscosity after large earthquakes, yet the microphysical mechanism responsible for this behavior remains subject of debate. Here, we present new gas‐medium apparatus experiments at 1100–1200°C on pre‐dried, annealed Åheim dunite (grain size of 400 μ ${\upmu }$m ...

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.

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

Geophysical 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
