Ground deformation investigation over Taiyuan Basin (China) by InSAR technology

Taiyuan Basin is one of the regions with complex geological structure and frequent seismic activities in China. Because of groundwater exploitation and tectonic activity, land subsidence has occurred widely in this region. For disaster prevention and mitigation, obtaining ground deformation characteristics within the basin is an urgent requirement. The Interferometric Synthetic Aperture Radar (InSAR) was used for mapping the ground deformation in this area. The ground deformation characteristics over Taiyuan Basin from 2007 to 2011 were obtained and the cross-correlation between the regional ground subsidence and fault activity were analyzed.
