    Abstract: 台灣北部的臺北盆地為人口密集、高度開發建設區域且為台灣現今政治經濟中心,西有山腳斷層,為此區域最主要的活動斷層;北有近期研究重點的大屯火山群,因此對於此區域的地表變形監測乃現今重要之課題。
    ;The triangular-shaped Taipei basin locates in the northern Taiwan and has been developed into the most densely populated area and also the capital of politics and economics in Taiwan.
    Taipei basin is well developed and amenable to research gathering using the Differential Interferometric Synthetic Aperture Radar (DInSAR) technique but the mountainous areas surrounding the basin are mostly covered with densely vegetations that reduce the signal-to-noise ratio in the InSAR interferograms.
    In this study, we aim to measure the ground deformation of northern Taiwan by processing the spaceborne radar interferometry data of ALOS acquired from 2007 to 2011 using the PSInSAR technique. The mean Line of Sight (LOS) velocity field of up to 8 mm/yr in the central Tatun volcanic area was measured, and up to 5 mm/yr inside the Taipei basin with higher rates at the hanging wall of the Sanchiao fault than the footwall was also revealed. We also integrated GPS and PSInSAR measurements to resolve a three-domensional ground motion across the study area. The result shows that the Tatun volcano and Keelung areas have experienced ground uplift, with notable horizontal extension across and perpendicular to the northern Sanchiao fault. This motion may relate to the subsurface hydrothermal activities beneath the Tatun area.
