Tectonic Re‐Organization and Onset of South Caspian Escape Tectonics at 1.8–2.4 Ma

Basin Research, Volume 38, Issue 6, November‐December 2026.
We show that the presently active tectonics of the South Caspian began relatively recently, likely in the range 1.8–2.4 Myr and replacing an older tectonic configuration ending in the Miocene at ~6 Ma. The various short‐lived stages in the destruction of the South Caspian have potential for insight into the late stages of basin closure and the ...

Revealing the Hydrothermal System of La Soufrière Volcano (Guadeloupe) Through Nodal Ambient Noise Tomography

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract La Soufri'ere de Guadeloupe is an active volcano of the Lesser Antilles Volcanic Arc. Its last eruption halted in 1977, yet hydrothermal activity has increased over recent years, raising summit instability hazards. The link between hydrothermal fluids and detachment landslide surfaces is well established and exacerbated by inflation ...

Assessment of the potential of MERIS near-infrared water vapour products to correct ASAR interferometric measurements [PDF]

, 2006
Atmospheric water vapour is a major limitation for high precision Interferometric Synthetic Aperture Radar (InSAR) applications due to its significant impact on microwave signals.

Constraining Fault Kinematics and India‐Tarim Convergence Partitioning in Southwestern Tibet With Geodetic Block Modeling

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract How the convergent strain between the India Plate and the Tarim basin is partitioned by active faults and off‐fault deformation in southwestern Tibet is poorly understood due to limited knowledge of strain localisation and fault kinematics. In this study, we derive high‐resolution velocity fields for the southwestern Tibetan Plateau using both

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.

Estimation of the fault geometry of the Median Tectonic Line (MTL) in Eastern Shikoku, Southwestern Japan, via GNSS and InSAR time series analysis

Earth, Planets and Space
The Median Tectonic Line (MTL) is one of the largest active fault systems in Japan. Whether the active MTL fault is north-dipping or near-vertical is still under debate.

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

Applicability of two grey models in earth-surface subsidence prediction of mining area

Gong-kuang zidonghua, 2020
Existing dynamic single-point subsidence prediction methods of mining area earth-surface are mainly based on traditional leveling measurement data, which have single monitoring mode, high cost and easily destroyed observation points, and cannot guarantee

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

Geophysical 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 ...
