Short summary
Land subsidence due to groundwater extraction and tectonic activity is separated by using the conceptual model proposed in this study. The contributions of land subsidence quantity from different factors at different locations are different due to the complex tectonic situation in this area. The assessment results show that the deep deformation is induced not only by tectonic activity but also by hydraulic loading. An increase of rainfall could induce a compressed deep deformation.
