复杂地震台网的泛聚结构与C~0.85标度

Universal clustering structure and C~0.85 scaling in complex earthquake networks

Sumiyoshi Abe, Norikazu Suzuki

摘要:

地震台网以一种特殊的方式捕捉到了地震活动的复杂性。给出了一个地震资料,并讨论了[S. Abe,N,Suzuki,Europhys. Lett. 65(2004)581]包含小区的大小作为单个参数,所考虑的地理区域被划分成小区。然后,网络的特性通常取决于小区的大小。在这里,网络的聚类系数,C,对细胞大小的依赖关系进行了研究。值得注意的是,由取自加利福尼亚、日本和伊朗的地震资料构建的地震台网的C对于重新标度的无量纲单元尺寸的每个值都很好地吻合。结果发现,在加利福尼亚州和日本的网络是三维的,而在伊朗的一个是二维的。此外,当无量纲单元尺寸大于某一共同值时,这三种网络的C值单调收敛到C~0.85,突出了地震网络概念的普遍性。的结果,以了解地震活动的物理意义进行了讨论。

英文摘要:

Earthquake network captures the complexity of seismicity in a peculiar manner. Given a seismic data, the procedure of constructing an earthquake network proposed in [S. Abe, N, Suzuki, Europhys. Lett. 65 (2004) 581] contains as a single parameter the size of the cells, into which a geographical region under consideration is divided. Then, the characteristics of the network depend on the cell size, in general. Here, the dependency of the clustering coefficient, C, of network on the cell size is studied. Remarkably, C of the earthquake networks constructed from the seismic data taken from California, Japan and Iran well coincide for each value of the rescaled dimensionless cell size. It is found that the networks in California and Japan are three-dimensional, whereas the one in Iran is rather two-dimensional. In addition, the values of C of all these three networks monotonically converge to C~0.85 as the dimensionless cell size becomes larger than a common value, highlighting a universal aspect of the concept of earthquake network. An implication of the result to understanding the physics of seismicity is discussed.
