根据地震活动表现出的网络动力学行为和地震系统所具有的时空复杂性，从复杂网络的角度分析地震活动。采用基于时空影响域的地震网络构造方法，对地震网络进行 k-核解析。实验结果表明，对地震网络进行 k-核解析得到的最高核的节点彼此聚集在一起。通过分析最高核节点与大地震的位置关系，发现大地震发生的地点与最高核节点所在的位置相邻。在一些大地震发生前，地震网络的最高核数会迅速增加，在大地震发生时最高核数达到最大值，大地震发生后最高核数又恢复到稳定状态。地震网络的 k-核解析为我们分析地震系统和研究地震的发生规律提供了一种新的途径。

According to the dynamical behavior of seismic activity and the spatio-temporal complexity of seismic system,this paper analyzed the seismic activities from the perspective of complex network.Using the solution based on space-time influence domain to construct earthquake network,a method of k-core de-composition was applied to the earthquake networks.The experiment result shows that the nodes in the highest layer cluster together.An important phe-nomenon is found that the strong quakes tend to occur at the location where the nodes in the highest layer are by analyzing their location information.What is more,the value of the highest layer will rapidly increase before a strong quake, then it will reach the maximum when a strong quake occurs,finally it will re-turn to a stable state.k-core decomposition of earthquake networks will provide a new way for us to analyze and research the seismological system.
