Stochastic properties of broadband strong motions are investigated using the fractal source model. The model is described by the limited dynamic data reflecting uncertainty and heterogeneity on the fault plane. The soil ground model for source-site path is presented by the theoretical Green's function of the multi-layered half space. The simultaneous simulation test has been tried for the recorded ground motions at some sites in the 1994 Northridge earthquake and the 2000 Western Tottori prefecture earthquake. The average spectra and the duration time of the synthetics correspond well with those of the observed within 20 kilometers from the fault region.
