Abstract StackingInSAR technology was used to measure the average crustal deformation rate of Linfen Basin and its boundary faults during 2003-2010.The results show that the inner part of Linfen Basin was subsiding and the mountains on both sides were rising relatively. The differential movement rate in middle section（YuliYucun）of Luoyunshan Fault was 4 mm/a, the rate in southern section（FanjiazhuangXiweikou）was 6 mm/a, and the rate around the Fault was about 2 mm/a, which corresponds with the result of the crossfault leveling at the same time. Within Linfen Basin, different tectonic units had different deformation patterns, the rate increased gradually from north to south. The rate in the northern part and in the southern part of HongtongLinfen Depression was 0-4 mm/a and 4-8 mm/a respectively. The Xiangfen Bulge was stable. The rate in the northeast part of Houma Depression was 4-8 mm/a, and 8-12 mm/a in the west part.
