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 ...

Large‐Scale Deformation, Strain Characteristics, and Locking Distribution of the Qilian‐Haiyuan Fault System

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The Qilian‐Haiyuan fault system is the main tectonic boundary of the northeastern Tibetan Plateau, controlling the regional tectonic deformation and seismic activity. Extensive Sentinel‐1 SAR data (2014–2021) are used to map the regional tectonic deformation, strain distribution, and locking along primary and secondary faults.

InSAR Ground Deformation and Pumping Energy Consumption Reveal Urban Water Security

Water Resources Research, Volume 62, Issue 1, January 2026.
Abstract Water resource assessments are critical for ensuring water security (WS), particularly in rapidly urbanizing regions with increasing water demand and limited water monitoring capabilities. Earth observations and indirect indicators of surface and groundwater changes are valuable tools for developing such assessments.

A Novel Approach for Predicting Mining Subsidence in Near‐Horizontal Coal Seams by Coupling Key Stratum and Stochastic Medium Theories

Geofluids, Volume 2026, Issue 1, 2026.
With the increasing scale and intensity of coal mining, the subsidence range of the goaf continues to expand, seriously affecting the stability of surface buildings and restricting the ecological environment protection of mining areas. To enrich the discipline system of mining subsidence and improve prediction accuracy, this study clarifies the ...
