Abstract：At present，two main stochastic models，point-source model and finite-fault model，are adopted to simulate ground motions. In this article，the stochastic point-source model is adopted to simulate the minor-moderate magnitude Sunan earthquake (ML=4.5，19 December 1988) and the result is reasonable. The stochastic point-source model and finite-fault model are used to simulate near-source strong ground motions for Sunan strong earthquake (Ms=5.7，22 November 1988)，and the results show that the finite-fault effect should be considered in near-source ground motion estimation.
