地震序列提取的时空耦合距离方法研究
|
摘要
提出一种从地震目录中以时空耦合距离分析方法为基础,识别强震的前震和余震,并形成序列目录的新方法。在动态迭代计算时空关联系数与时空耦合距离过程中,定义在时空耦合距离构架中,由小于或等于截止长度的地震构成该强震的地震序列。用此方法,可以按强震逐个识别其前震余震,形成序列目录。我们用它识别处理了唐山7.8级强震的余震,并为该强震建立了序列目录。
In this paper, a method for extracting an earthquake sequence from earthquake catalogue is presented based on the spatio-temporal coupling distance. In the dynamic calculation of spatio-temporal transfer coefficient and spatio-temporal coupling distance, a strong earthquake sequence is defined as the earthquakes with spatio-temporal distance that is equal to or less than the cut-off distance. With this method, the aftershock of Tangshan earthquake was distinguished and an earthquake sequence was set up.
