Monitoring and early-warning of surface deformation in mine goaf based on InSAR
To study the monitoring and early warning ability of DInSAR and SBAS InSAR for mine earthquake collapse in goaf area, this paper uses the two InSAR techniques to process the 11 scene C-band Sentinel-1A SAR images before and after the mine earthquake to ...

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