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.

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.

On the Use of Anisotropic Covariance Models in Estimating Atmospheric DInSAR Contributions

IEEE Geoscience and Remote Sensing Letters, 2011
When studying geophysical processes through Differential SAR Interferometry (DInSAR), it is often necessary to estimate and subtract signals due to atmospheric inhomogeneities. To this end, stochastic models are often used to describe atmospheric phase delays in DInSAR data. As a first approximation, these can be modelled as isotropic, though this is a

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.

3D Volumetric Strain Distribution of the Cerro Prieto Geothermal Field Inferred From Inverse Modeling of InSAR and Leveling Data

Geophysical Research Letters, Volume 52, Issue 13, 16 July 2025.
Abstract Advanced Interferometric Synthetic Aperture Radar (InSAR) data has led to an extensive observation of Earth's surface displacements. Whereas the combined use of high‐resolution InSAR, leveling and GPS data may enable highly detailed three‐dimensional deformation models, publicly available modeling and inversion algorithms either seek a single ...
