Abstract:The current crustal deformation of the Tangshan area was analyzed with FEA numerical method under constraint of GPS observation,using physical contact model to obtain the discontinuous motion of faults.The results of simulation show that the movement of the faults in Tangshan area is different from each others.The faults in Tangshan area are right lateral slipping for Tangshan Block is pushed by Shanhaiguan plate.Jiyunhe fault zone has accumulated higher stain,therefore seismic risk there is higher.
