摘要
本文在二维平面上设计了一个模拟地震活动性的细胞自动机模型，分析了模拟地震序列的地震活动性，并探讨了强震前场兆和源兆的物理机制。结果表明，模型的地震序列很好地反映了实际地震的丛集特性、幂律关系和空间转移概率的稳定性等特点。
In this paper a 2-D cellular automation model of seismicity is designed,the seismicity of the synthetic earthquakes is analyzed and the physical mechanisms of field precursors and source precursors before a strong earthquake are discussed.The results show that the cluster-ing,frequency-magnitude power law relation and spatial transfer probability of synthetic earth-quakes are consistent with the actual earthquakes.
