本文提出一种从地震目录中识别强震的前震和余震并形成序列目录的新方法,即:以单键群(SLC)分析方法为基础,定义在SLC构架中,由小于或等于特征键长的键所形成的许多链中,那些处在与某个强震联通的链上的地震就与该强震构成一个地震序列;在此序列中,该强震为主震,发生于它之前的事件为前震,之后的为余震。用此方法,可以按强震逐个识别其前震余震,并形成其序列目录。我们用它识别处理了海城74级和昆仑山—阿尔金山弧型顶部地区60级以上强震的前震和余震,并为各强震建立了序列目录。
In this paper, we propose a new method to identify foreshock and aftershocks of strong earthquakes from seismic catalogs and form sequence catalogs based on single-bond cluster analysis (SLC), which is defined in the SLC framework and consists of less than or equal to the characteristic bond length Among the many chains formed by the keys, the earthquakes in the chain linked to a strong earthquake form an earthquake sequence with the strong earthquake; in this sequence the strong earthquake is the main shock that took place before it The event was a foreshock, followed by an aftershock. With this method, one can identify the foreshock aftershock one by one according to the strong earthquake and form its sequence catalog. We use it to identify and process the foreshocks and aftershocks of the Haicheng 74 and Kunlun Mountains-Altun arc top-level strong earthquakes of magnitude 60 and establish a sequence catalog for each strong earthquake.
