英文摘要	While seismic wave velocity shows large-scale deterministic geological structures, ubiquitous small-scale micro-fractures often cause statistic variations. Although seismic waves traveling through the Earth act as a low-pass filter and smooth out some small indeterministic components, those statistic in other words self-organized features exist underground. Six types of self-organized media are frequently used in seismology such as Gaussian, Exponential, self-similar, white noise, Flicker noise and Brown noise. From their filters, we compare different self-organized models with seismic recordings in conjunction with finite difference methods. The results show that various self-organized models of amplitude, energy and frequency will produce different synthetic seismograms. Thus we can make good use of this complex information to interpret field data well.
