| Abstract: | A consistent velocity field was derived from the GPS observations carried out in north China starting from 1999.A block dislocation model was established and the characteristics of major tectonic blocks and faults were analyzed using the simulated annealing algorithm.The result shows that the Euler vectors of all tectonic blocks are relatively smaller with respect to the South China block.Fault activities are insignificant generally.Zhangjiakou Penglai Tectonic Belt is undergoing left lateral motion，with a slipping rate of 1 mm/a.The western segment and the eastern segment of the Belt are different in terms of slipping magnitude，with locking depths in 40 km and 30 km，respectively.Shanxi Fault Belt is characterized by a right lateral slipping with a rate of 1 mm/a，and a locking depth of 30 km.Tanlu Fault exhibits right lateral motion，with a slipping rate of 1 mm/a，and a locking depth of 40 km. |
