Abstract

Using the interferometric fringes generated by the phase difference among three SAR images acquired by the ERS-1/2 satellite, based on a standard elastic dislocation formation for coseismic displacement, the seismic fault parameters of Zhangbei-Shangyi earthquake are estimated. It is suggested that the seismic fault of Zhangbei-Shangyi earthquake is a thrust fault dipping SW with a large right-lateral displacement component. The strike, dip are 95°, 30°, respectively on a fault patch 12 km long by 14 km wide. Its hypocenter is located at N40°58´, E114°21´, 7.5 km depth. The estimated slip vector is 0.728 m with a rake of 105.95° the trend of slip is NW13.26°
