Abstract

The waveform cross correlation technique is used to detect signals from aftershocks of the ML = 6.1, August 14, 2016, Sakhalin earthquake using regional seismic network data. Regular P- and S-wave phase arrivals are associated with seismic sources; the resulting cross correlation bulletin is compared with a standard seismic bulletin for the same aftershock sequence. An advantage of the cross correlation bulletin is that it has more detected seismic events tied to three or more stations and a lower catalog completeness threshold; even the epicenters of the weakest aftershocks are located with greater accuracy. The exact aftershock locations tend to cluster along a narrow zone related to the Central Sakhalin Fault.

使用波形互相关重建2016年8月14日萨哈林地震的余震序列

摘要

波形互相关技术用于使用区域地震网络数据检测2016年8月14日萨哈林地震ML = 6.1余震的信号。常规的P波和S波相位到达与地震源有关。对于相同的余震序列，将得到的互相关公告与标准地震公告进行比较。互相关公告的一个优点是，它具有更多的与三个或更多站点相关的检测地震事件，并且目录完整性阈值较低。即使是最弱余震的震中也能以更高的精度定位。确切的余震位置倾向于聚集在与萨哈林中央断裂有关的狭窄区域。
