摘要
震中距100°左右的地震,位于远震与极远震之间,特征既像远震又像极远震,震相较难分析。为了提高对该震中距地震的速报能力,对山西省地震局太原基准地震台记录的该震中距的地震事件进行了分析,总结了其震相特征及规律。
The earthquakes with epicenter distance around 100 degree are of characteristics of both teleseismic and far-teleseismic ones,usually difficult to be analyzed.In order to report more rapidly for earthquakes around this distance,the earthquake traces recorded by Taiyuan Reference Seismological Station of Earthquake Administration of Shanxi Province are analyzed,and the characteristics and rule of their seismic phases are summarized.
