Olami-Feder-Christensen模型的复发事件网络
Network of recurrent events for the Olami-Feder-Christensen model
摘要：
我们数值研究的离散弹簧块模型引入Olami，Feder和Christensen（OFC）模拟地震的动力学，并调查在何种程度上这个简单的模型是能够重现所观察到的时空聚集的地震。根据最近提出的方法来表征这种集群网络的经常性事件[地球物理。保留信函{ \bf 33}，L1304，2006]，我们发现，对于由OFC模型生成的合成目录，这些网络具有许多非平凡的统计性质。这包括特征度分布--与实际地震活动观察到的非常相似。然而，OFC模型和地震目录之间也存在显着差异，表明这种简单的模型不足以解释地震活动时空聚类的某些方面。
英文摘要：
We numerically study the dynamics of a discrete spring-block model introduced by Olami, Feder and Christensen (OFC) to mimic earthquakes and investigate to which extent this simple model is able to reproduce the observed spatiotemporal clustering of seismicty. Following a recently proposed method to characterize such clustering by networks of recurrent events [Geophys. Res. Lett. {\bf 33}, L1304, 2006], we find that for synthetic catalogs generated by the OFC model these networks have many non-trivial statistical properties. This includes characteristic degree distributions -- very similar to what has been observed for real seismicity. There are, however, also significant differences between the OFC model and earthquake catalogs indicating that this simple model is insufficient to account for certain aspects of the spatiotemporal clustering of seismicity.
