设计了２００×２００×１０网格的三维大型地震细胞自动机模型，生成了９４３０４个“地震”事件．结果表明，对于能量－频度的分形关系小地震和大地震有不同的无标度区；较大地震容易在相对较短时间、较近距离内相互互应地发生 A 3D large-scale seismic cellular automaton model with 200 × 200 × 10 grids was designed and 94,304 “earthquakes” events were generated. The results show that there is a different scale-free zone for energy-frequency fractal correlation between small earthquakes and large earthquakes; larger earthquakes are likely to interact with each other in a relatively short time and at a relatively short distance
