It is 2 compared with the famous source spectral model ( ω ) by Brune and the source spectral model with double corner frequencies by Atkinson in different magnitudes. The result shows that the source spectrum by this paper is very close to Brune’s for small magnitude and is close to Atkinson’s for large magnitude. Afterwards, the source spectral model is combined with the dynamic corner frequency to eliminate the effect of the sub-fault size on the high frequency radiating energy. The improved source spectral model was verified finally from the comparing the ground motion synthesized with the records at three rock sites in Northridge earthquake, 1994.
