In order to use the synthetic ground motions calculated from the fault model as input motion for earthquake resistant design of structures, it is necessary to estimate the characteristics of the source time function correctly. In this paper, the estimation method of the source time function by applying the auto regressive (AR) model to the observed ground motions for the purpose of estimating the dynamic properties of the ground surface and the seismic path is proposed. Further, this procedure is applied to the synthetic waves calculated from the fault model in order to verify this method. As a result, the waveform obtained by using this method corresponds to the source time function of the seismic moment. These results agree with the condition given for the fault model analysis and it is pointed that this analytical method using the AR model is available to estimate the source time function from the observed ground motions.
