Abstract
The Linfen–Yuncheng basin is an area prone to geological disasters, such as surface subsidence, ground fissuring, fault activity, and earthquakes. For the purpose of disaster prevention and mitigation, Interferometric Synthetic Aperture Radar (InSAR) was used to map ground deformation in this area. After the ground deformation characteristics over the Linfen–Yuncheng basin were obtained, the cross-correlations among regional ground subsidence, fault activity, and underground water level were analyzed in detail. Additionally, an area of abnormal deformation was found and examined. Through time series deformation monitoring and mechanism inversion, we found that the abnormal deformation was related mainly to excessive groundwater exploitation.
Highlights
The Shanxi fault belt basin is a Cenozoic fault basin that has strong earthquake activity.The Linfen–Yuncheng basin is located in the south-central region of the Shanxi fault belt basin, where the crustal structure is especially complex and seismic activity is very strong [1,2] (Figure 1).In total, 10 earthquakes with Ms ě 5.0 have been recorded since A

Linfen–Yuncheng basin has suffered from severe geo-hazards, including large scale land subsidence and small scale fault activity, which has caused serious infrastructure damages and property losses
Summary
The Shanxi fault belt basin is a Cenozoic fault basin that has strong earthquake activity.The Linfen–Yuncheng basin is located in the south-central region of the Shanxi fault belt basin, where the crustal structure is especially complex and seismic activity is very strong [1,2] (Figure 1).In total, 10 earthquakes with Ms ě 5.0 have been recorded since A. The Shanxi fault belt basin is a Cenozoic fault basin that has strong earthquake activity. The Linfen–Yuncheng basin is located in the south-central region of the Shanxi fault belt basin, where the crustal structure is especially complex and seismic activity is very strong [1,2] (Figure 1). 10 earthquakes with Ms ě 5.0 have been recorded since A. According to modern seismic network records, moderate–small earthquakes have been more frequent in this area in the recent past [3,4] (Figure 1). Ground subsidence, ground fissuring, fault activity, and abnormal deformation have been observed and have received substantial attention from the local government [5,6]. For the purpose of disaster prevention and mitigation, there is an urgent need to characterize the ground deformation characteristics within the basin
