Consistent measurements of crustal deformation of the Taiwan Island by SAR interferometry and continuous GPS measurements

要旨：
The main goal of this study is to validate the active deformation across an ongoing collisional orogenic belt in Taiwan by space-borne SAR interferometry (InSAR) with constrains of dense continuous GPS network and previse precise leveling measurements to monitor the ground deformation. The validated deformation can provide the important knowledge for study in earthquake cycle, mountain building process and natural disaster assessment for earthquakes, active faults, land subsidence and landslide. The GPS network of Taiwan has more than 400 continuous GPS stations, which is definitively powerful for nature-hazard-related issue and even to a wider community. In addition, 42 precise leveling routes has covered major active faults with co-sited GPS stations. Nonetheless such a powerful geodetic measurements have some limitations, especially the spatial density of data and temporal coverage for a lot of applications. For this limitation, we propose herein a study to dramatically increase the spatial and temporal ground deformation at the scale of the whole Taiwan Island by SAR interferometry with the constrains of continuous GPS and precise leveling measurements.We use these results to characterize interesting transient deformations induced by hydrological change (and in the earthquake cycle occurring in several places in Taiwan. In Taipei metropolitan area, short-term fluctuation of surface deformation is revealed by high resolution X-band SAR interferometry and precise leveling. In southwestern Taiwan, recent geodetic observations (InSAR and leveling) in the Tainan area have revealed very temporal changes in the active deformation pattern of the area from the period 1996-1999 to 2005-2011. These observations definitely deserve a more systematic investigation at the scale of southwestern Taiwan. In addition, high uplift rate related to fault-related folding is observed in SW Taiwan. The combination of InSAR measurements with continuous GPS and leveling data allow us to characterize the deformation through time, leading to develop new hypothesis and models on the physical processes of transient deformations.
