3D coseismic Displacement of 2010 Darfield, New Zealand earthquake estimated from multi-aperture InSAR and D-InSAR measurements

, 2012
Differential interferometric synthetic aperture radar (D-InSAR) measures ground deformation only along the line-of-sight (LOS) of the radar, which limits the capability of D-InSAR in investigating the surface damages and the focus mechanisms of ...

ESTIMATION OF ATMOSPHERIC EFFECTS OF RADARSAT-2 D-InSAR PRODUCT USING GROUNDBASEDAND SPACEBORNE METEROLOGICAL DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Differential Interferometric synthetic aperture RADAR (D-InSAR) has emerged as one of the influential tools for the measurement of Earth’s topography deformation. The temporal variability of atmosphere plays a contaminative role in degrading the accuracy

Water Storage Capacity Dynamics in Drained Boreal Peatlands: Responses to Rewetting and Climate Change

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Historical peatland drainage resulted in surface subsidence and reduced water storage capacity (WSC), a process that can be exacerbated by climate change. We assessed the effects of rewetting on WSC using mesocosm experiments in climate chambers, field measurements, and Interferometric Synthetic Aperture Radar (InSAR) analysis.

Mining Subsidence Monitoring Based on Combination Method of Multi-Look and Full-Resolution Interferogram

Meikuang Anquan, 2020
In view of the characteristics of mining subsidence with large amplitude and small scope, a method of mining subsidence monitoring by combining multi-look with full-resolution interferogram is put forward.

Assessing Co‐Located NISAR and Sentinel‐1 Observations for Atmospheric Characterization

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 19, 16 October 2026.
Abstract Tropospheric delay remains one of the largest sources of uncertainty in repeat‐pass Interferometric Synthetic Aperture Radar (InSAR) measurements, while accurate three‐dimensional deformation retrieval continues to be limited by the geometry of current spaceborne SAR systems.

Shortcomings of InSAR for studying megathrust earthquakes: The case of the M w 9.0 Tohoku-Oki earthquake [PDF]

, 2012
Interferometric Synthetic Aperture Radar (InSAR) observations are sometimes the only geodetic data of large subduction-zone earthquakes. However, these data usually suffer from spatially long-wavelength orbital and atmospheric errors that can be ...

Adaptive Fusion of Aspect Constraint and Strain Model for InSAR 3-D Deformation Inversion

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Accurate and high-resolution monitoring of 3-D surface deformation is essential for analyzing and mitigating geological hazards. Interferometric synthetic aperture radar (InSAR) has become a pivotal technique for monitoring surface deformation due to its

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, Volume 37, Issue 4, Page 692-712, October/December 2026.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.
