| Summary: | 碩士 === 國立中央大學 === 地球物理研究所 === 100 === I used the PSInSAR and Small baseline techniques to investigate the surface deformation of the northern Taiwan area, including the Taipei basin and its surrounding mountain areas. Integrating the Persistent Scatterer Interferometry (PSInSAR) and Small baseline subset InSAR (SBAS) results, I observed some deformation events in northern Taiwan including: 1) The Taipei basin had experienced uplift from 1993 to 2001, which may relate to aquifer rebound. 2) In contrast the Taipei basin had subsided from 2003 to 2008 possibly due to massive pumping of groundwater. 3) In the western of Taipei basin, the ground subsidence from 1993 to 2008 may be caused by the compaction of shallow sediments and interseismic deformation of the Sanchiao fault. 4) The Da-You-Kan area had been uplifted from 2003 to 2008 that may be caused by magmatic or geothermal activities. Further comparisons between the PSInSAR, Small baseline, and the corresponding leveling data show a coincident pattern, and therefore largely improve the authenticity of radar interferometry.
