Abstract：High precision GPS horizontal velocities of GPS seismic monitoring network and gravity data were used to estimate the block motion and major fault slip rate in Fujian Area.The results are as follows: Due to the influence of collision of the Eurasian, Philippine Sea and Pacific plates, crustal deformation of blocks in Fujian area are prominently in a clockwise rotation.Further, this leads to left-slip motion along the NE-striking faults and right-slip motion along the NW-striking faults. The Changle-Zhaoan, Shaowu-Heyuan and Yongan-Jinjiang faults are the most active left-lateral faults in the region, with a rate of 0.7±1.3mm/a, 0.7±1.7mm/a and 0.6±1.8 mm/a respectively, and the Jiulong river downstream area has a right-lateral slip rate of 0.5±1.7mm/a.
