Spatiotemporal characteristics analysis of ground subsidence in Wuhan based on SBAS-InSAR

IOP Conference Series: Earth and Environmental Science, 2022
Abstract Aiming at the problem of uneven ground subsidence in Wuhan, using the Sentinel-1A SAR image data of 36 scenes from July 2017 to June 2020, the SBAS-InSAR was used to extract the ground subsidence information in Wuhan. Influence of factors such as urban construction, industrial development, rainfall, and carbonate karstification ...

Intelligent Environmental Hazards Detection in Transmission Line Construction Area Based on Remote Sensing and GIS

Engineering Reports, Volume 8, Issue 4, April 2026.
The test results displayed reveal that the proposed method efficiently accomplishes the remote sensing image processing of the area, yielding a differential interferogram of the image. This interferogram accurately represents the area and provides a solid foundation for calculating the environmental hazard zone within the construction area.

Beyond Rock Glaciers: Investigating Meltwater Contribution and Water Quality in High‐Mountain Springs From Different Landforms

Hydrological Processes, Volume 40, Issue 4, April 2026.
We investigated the water chemistry of springs from different landforms in high‐elevation Alpine catchments. Only in predisposing lithological settings, springs from landforms most likely influenced by ice had a poor water quality with high dissolved concentrations of metals.

Surface Deformation of the Nanga Parbat Crustal Diapir in the Northwestern Himalaya Imaged With GNSS and InSAR

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract The Nanga Parbat–Haramosh Massif located in the northwestern syntaxis of the Himalaya is an antiformal structure considered as a crustal diapir undergoing exhumation at a rate larger than 10 mm/yr since 1 Ma. Using GNSS horizontal surface velocities and a vertical and east–west decomposition of the Sentinel‐1 interferometric line‐of‐sight ...

Quantifying Seasonal Deformation Signals Using InSAR and Groundwater Models in the Mississippi River Delta, Baton Rouge, Louisiana

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 4, April 2026.
Abstract Seasonal land motion can be caused by processes above or below Earth's surface, often linked to natural changes in the hydrological cycle. In coastal deltaic systems, the coupling of water level changes between rivers and aquifers may cause significant surface deformation, but this process is poorly understood.

Frictional Heterogeneity Governs Slip Partitioning and Seismic Hazard in the 2023 Turkey Earthquake Doublet

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Quantifying fault frictional properties is fundamental to understanding slip behavior and seismic hazard. We analyze 2 years of Sentinel‐1 SAR data following the 2023 Turkey earthquake doublet using Independent Component Analysis‐enhanced Small Baseline Subset‐InSAR, to resolve postseismic deformation and invert for afterslip on the East ...
