谈远震特别区域震相记录特征与震相识别——以大同国家测震台观测资料为例

Seismic Phase Recording Characteristics and Seismic Phase Identification for Distant Earthquakes in Special Distance Range: Taking the Observation Data of Datong National Seismic Station as an Example

以大同国家测震台观测资料为例,总结了震中距10~°50°范围内特别区域地震震相特征和震相识别的方法,对震相识别的难点进行了说明,以图例的形式为判读震相提供了依据。

Taking the observation data of Datong national seismic station as an example,the seismic phase characteristics and seismic phase identification methods of earthquakes occurred in special distance range of 10°～50° away epicenters are summarized,and the difficulties for seismic phase identification are also explained by illustration,which can be taken as references for identifying seismic phases.
