Abstract This study focused on the earthquake network properties of Southern California. The event synchronization method was used to create an earthquake network of the aforementioned region. Local network measurements were utilized to investigate the most active and prominent subregions and their effects on the earthquake dynamics of the region. These measurements showed that two regions (the Eastern California Shear Zone (ECSZ) and the region that begins at the South end of the San Andreas Fault Zone, continues through the San Jacinto and Elsinore Faults, and terminates at the Lugano Salada Fault) dominate the earthquake dynamics of Southern California. Both regions are seismologically active and exhibit spatial continuity from the network perspective. Additionally, many cells in these regions serve as bridges for stress transfers. It appears that not only are few of these cells responsible for the earthquake dynamics at the ECSZ but also nearly the entire ECSZ region plays an important role in earthquake activity. The Garlock Fault Zone, a small region near Los Angeles, and a small region along the San Diego Trough Fault had no large earthquake during the analyzed time region, but these measurements show their potential for future activity.

基于事件同步法的地震空间动力学分析

摘要 本研究重点研究南加州地震网络特性。事件同步方法用于创建上述区域的地震网络。当地网络测量被用来调查最活跃和最突出的子区域及其对该地区地震动力学的影响。这些测量表明,两个区域(东加利福尼亚剪切带 (ECSZ) 和从圣安德烈亚斯断层带南端开始,继续穿过圣哈辛托和埃尔西诺断层,并在卢加诺萨拉达断层处终止的区域)占主导地位南加州地震动力学。从网络的角度来看,这两个区域都具有地震活动性,并表现出空间连续性。此外,这些区域中的许多细胞充当应力传递的桥梁。似乎不仅这些细胞中很少有负责 ECSZ 地震动力学的细胞,而且几乎整个 ECSZ 区域在地震活动中都起着重要作用。Garlock 断层带、洛杉矶附近的一个小区域和圣地亚哥海槽断层沿线的一个小区域在分析的时间区域内没有发生大地震,但这些测量结果显示了它们未来活动的潜力。
