The statistical fault model for seismic spectrum is extended to include infinite number of correlation lengths. This model, compared to the usual statistical model which has one set of temporal and spatial correlation lengths related to the fault dimension, gives much enhanced spectral amplitude for high frequency range. In constructing the model we assume self-similarity for the distribution of correlation lengths. As is expected, the spectral density in high frequency range becomes larger by introducing more coherencies in small scale range.
