Retrieving Three‐Dimensional Deformation in Groundwater Pumping Areas Based on InSAR Data

Water Resources Research, Volume 62, Issue 2, February 2026.
Abstract Monitoring three‐dimensional (3D) surface deformation in groundwater pumping areas remains a significant challenge, as conventional InSAR techniques are constrained by their limited sensitivity to north‐south displacement. This study develops an inversion approach—the Vertical Gradient‐Constrained Strain Model (VG‐SM3D)—that combines multi ...

REDEFINING SUBSIDENCE AND UPLIFT HOTSPOTS ON JAVA ISLAND, INDONESIA: MULTI-TEMPORAL INSAR FOR LARGE-SCALE LAND DEFORMATION MAPPING

Rudarsko-geološko-naftni Zbornik
Java Island experiences complex and nonlinear land deformation resulting from the interplay of natural and anthropogenic factors. Previous studies predominantly investigated urban subsidence, leaving island-wide patterns less understood.

Surface ruptures and building damage of the 2003 Bam, Iran earthquake mapped by satellite synthetic apeerture radar interferometric correlation [PDF]

, 2005
We use the interferometric correlation from Envisat synthetic aperture radar (SAR) images to map the details of the surface ruptures related to the 26 December 2003 earthquake that devastated Bam, Iran.

Dynamic Boundaries of Antarctic Active Subglacial Lakes Reveal Underestimated Water Volume Change and Overestimated Lakebed Active Area

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract This study revisited 158 documented active subglacial lakes across Antarctica, applying a height‐change anomaly delineation algorithm to CryoSat‐2 and ICESat‐2 satellite altimetry data to assemble a 14.75‐year (2010.5–2025.25) time series of active subglacial lake dynamics.

Reservoir characterization in an underground gas storage field using joint inversion of flow and geodetic data [PDF]

, 2015
Characterization of reservoir properties like porosity and permeability in reservoir models typically relies on history matching of production data, well pressure data, and possibly other fluid-dynamical data.

Supershear Transitions and Bilateral Asymmetric Rupture of the 2025 Sagaing (Myanmar) Earthquake Revealed by Geodetic and Seismic Observations

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The Sagaing Fault (SF) accommodates major plate motion in Myanmar, yet large earthquakes along it have rarely been captured by modern geodetic and seismic observations. The 2025 Sagaing earthquake generated an exceptionally long rupture (∼535 km), offering a rare opportunity to investigate rupture dynamics along continental transform fault. We

Glacier motion estimation using SAR offset-tracking procedures [PDF]

, 2002
Two image-to-image patch offset techniques for estimating feature motion between satellite synthetic aperture radar (SAR) images are discussed. Intensity tracking, based on patch intensity cross-correlation optimization, and coherence tracking, based on

Characterization of Crustal Deformation During the May 2021 Nyiragongo Eruption Using InSAR and GNSS Data

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract We analyze Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite System (GNSS) data to characterize ground deformation and dike opening associated with the May 2021 Nyiragongo eruption. Despite documented eruptions in 1977 and 2002, Nyiragongo's magmatic system and its interaction with regional rifting remain poorly ...

Feature Enhancement of Interferometric Synthetic Aperture Radar Image Formation Using Sparse Bayesian Learning in Joint Sparsity Approach

Leida xuebao, 2018
A novel sparse Bayesian learning approach with a joint sparsity model is proposed for Interferometric Synthetic Aperture Radar (InSAR) image formation to realize the feature enhancements of interferometric phase denoising and speckle reduction.
