GNSS and InSAR Integration for 3‐D Crustal Deformation in California and Western Nevada

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract The regions of California and Nevada are shaped by dynamic tectonic and hydrologic processes that drive significant crustal deformation. In this study we use the method of Shen and Liu (2020), https://doi.org/10.1029/2019ea001036 to integrate Global Navigation Satellite System (GNSS) and Interferometric Synthetic Aperture Radar (InSAR ...

Refining 3D Displacement Fields and Coseismic Slip Models of the 2023 Kahramanmaraş Earthquakes Using Subswath and Burst Overlap Interferometry (SBOI)

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.
Abstract The 6 February 2023 Kahramanmaraş Earthquakes caused extensive deformation along the East Anatolian Fault Zone, producing significant north‐south displacements. Standard Interferometric Synthetic Aperture Radar (InSAR) methods face significant challenges in resolving near‐field deformation due to phase decorrelation caused by high displacement

Differential settlements monitoring in railway transition zones using satellite‐based remote sensing techniques

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 27, Page 4824-4844, 14 November 2025.
Abstract Railway track transitions are prone to uneven settlements and track geometry degradation. Traditional monitoring methods are limited in coverage, which highlights the need for novel solutions. This study proposes a method that systematically integrates the high spatial resolution of Persistent Scatterer Interferometric Synthetic Aperture Radar
