Peatland Surface Motion: Terminology, Measurement Approaches, Models and Insights From a Global Dataset

Ecohydrology, Volume 18, Issue 8, December 2025.
ABSTRACT The surface of peatlands is constantly in motion. While pristine mires are characterized by peat growth and reversible surface fluctuation, induced by water level fluctuations, drained peatlands show subsidence due to peat mineralization and physical compaction. Still, drained peatlands show smaller but marked short‐term surface fluctuation as

Integration of DInSAR and SBAS Techniques to Determine Mining-Related Deformations Using Sentinel-1 Data: The Case Study of Rydułtowy Mine in Poland

Remote Sensing, 2020
Underground coal exploitation often results in land-surface subsidence, the rate of which depends on geological characteristics, the mechanical properties of the rocks, and the applied extraction technology.

Satellite Geodesy Reveals Shallow, Transient Magma Intrusions at Sotará Volcano, Colombia

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 12, December 2025.
Abstract Sotará is a little‐known andesitic‐dacitic stratovolcano in southwestern Colombia. Although there are no recorded historical eruptions, the volcano shows clear evidence of geothermal activity, deformation, and volcano‐tectonic seismicity. Its remote location and rugged terrain pose challenges for access and routine monitoring.

Coseismic Kinematics and Early Afterslip Evolution of the 2025 Mw ${\mathbf{M}}_{\mathbf{w}}$ 7.1 Dingri Earthquake (Southern Tibet) From Space Geodesy

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract The 2025 Mw ${\mathrm{M}}_{\mathrm{w}}$ 7.1 Dingri earthquake is a large normal‐faulting event within the Southern Tibet Rift System. We use space‐borne radar interferometry to investigate both coseismic rupture and ∼3‐month early afterslip. Results show that this event ruptured a west‐dipping (48°) fault, exhibiting a predominant normal dip ...

Progressive Development of a Paraglacial Rock Slope Failure at Portage Glacier, Alaska

Journal of Geophysical Research: Earth Surface, Volume 130, Issue 11, November 2025.
Abstract Paraglacial landscapes are rapidly transforming as thinning and retreating glaciers expose adjacent slopes to new conditions. In Southcentral Alaska, a large slope instability at Portage Glacier has been deforming progressively up‐glacier over the past six decades.

Railway deformation detected by DInSAR over active sinkholes in the Ebro Valley evaporite karst, Spain [PDF]

Natural Hazards and Earth System Sciences, 2015
Subsidence was measured for the first time on railway tracks in the central sector of Ebro Valley (NE Spain) using Differential Synthetic Aperture Radar Interferometry (DInSAR) techniques. This area is affected by evaporite karst and the analysed railway

Monitoring of a multi‐span prestressed concrete bridge using satellite interferometric data and comparison with on‐site sensor results

Structural Concrete, Volume 26, Issue 5, Page 5430-5453, October 2025.
Abstract Satellite‐based Synthetic Aperture Radar Interferometry (InSAR) represents a promising supplement to traditional Structural Health Monitoring (SHM) methods, offering a non‐invasive solution that eliminates the need for sensor installations and provides extensive spatial coverage.

L2-norm deformation phase unwrapping in mining area driven by matrix pencil model

Meikuang Anquan
To address the limitations of traditional phase unwrapping (PU) approaches in differential interferometric synthetic aperture radar (DInSAR) technology which performs poorly in unwrapping low-coherence deformation interferograms in mining areas, an L2 ...

Mapping Ice Stream Sensitivity in the Amundsen Sector to Uncertainty in Ice Velocity Observations

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Satellite‐derived ice‐velocity products are essential for initializing ice‐sheet models and forecasting ice evolution in a warming climate. Understanding where sea‐level rise (SLR) projections are sensitive to observational errors is key to improve model accuracy and reduce uncertainty.
