On 4 July 2019 southern California was rattled by the largest earthquake to occur in the region in nearly 20 yr, a moment magnitude (⁠MW⁠) 6.4 earthquake that occurred near Ridgecrest approximately 200 km north of Los Angeles. It was followed on 6 July by a larger MW 7.1 earthquake. The distribution of aftershocks made it clear from the beginning that this was a complex earthquake sequence involving rupture on multiple faults. Unraveling the secrets of the sequence, consisting of over 100,000 events, will undoubtedly require years of research. Fortunately, researchers will be enabled...

关于2019年里奇克莱斯特地震序列的地震研究快报数据矿山焦点部分的序言

2019年7月4日，南加州受到该地区近20年内发生的最大地震的震撼，这是在洛杉矶以北200公里处的里奇克莱斯特附近发生的6.4级地震。随后在7月6日发生了7.1兆瓦以上的大地震。余震的分布从一开始就清楚表明，这是一个复杂的地震序列，涉及多个断层的破裂。揭开该序列的秘密，包括100,000多个事件，无疑将需要多年的研究。幸运的是，研究人员将被启用...
