| Abstract: | By the inversion method of uneven slippage of faults in the depths(Liu et al ., 1995) and using the crustal deformation data of six phases, the movement states of seismic fault of the Tangshan earthquake in five time periods before, during and after that earthquake are computed. The result of computation has revealed the movement process of seismic fault, during which the fault moved at an increasing rate before the quake, slipped suddenly during the quake, and became relaxed, adjusted and stabilized gradually after the quake. Moreover, the recurrence period of earthquakes in Tangshan is computed using the relation that the slippage of seismic fault bears with strain energy. |
