现代观点中的余震:复杂地震网络、老化和非马尔可夫性

Aftershocks in Modern Perspectives: Complex Earthquake Network, Aging, and Non-Markovianity

Sumiyoshi Abe, Norikazu Suzuki

摘要:

从复杂性科学的角度研究余震现象。特别是,三个不同的概念进行检查:(一)复杂的网络表示的地震活动性,(二)事件事件的相关性,(三)的影响,远程记忆。关于(i),它表明复杂地震网络的聚类系数在主震前后表现出一种特殊的行为。关于(ii),它被发现,余震的经验老化,相关的缩放举行。对于(iii),一类奇异马尔可夫过程所满足的标度关系被破坏,这意味着余震过程中存在长程记忆。

英文摘要:

The phenomenon of aftershocks is studied in view of science of complexity. In particular, three different concepts are examined: (i) the complex-network representation of seismicity, (ii) the event-event correlations, and (iii) the effects of long-range memory. Regarding (i), it is shown the clustering coefficient of the complex earthquake network exhibits a peculiar behavior at and after main shocks. Regarding (ii), it is found that aftershocks experience aging, and the associated scaling holds. And regarding (iii), the scaling relation to be satisfied by a class of singular Markovian processes is violated, implying the existence of the long-range memory in processes of aftershocks.
