长春地震台记录国内5级以上地震波形及震相特征分析

Characteristics of seismic waveform and phases of M_s≥5.0 earthquakes in China recorded by Changchun Seismic Station

从地质构造、波列特征、S-P到时差、震中距、主要震相、震源深度等方面对长春地震台2000年以来记录到的国内5级以上地震进行分析研究,总结出国内不同区域地震在长春地震台的波形记录特征和分析方法。

In this paper,the geological structure,feature of seismic wave train,arrival S-P time difference,opicentral distance,major seismic phase,focal depth,etc.of MS≥5. 0 earth-quakes in China recorded by Changchun Seismic Station after 2000 are studied.Then the characteristics of seismic waveform and the way of analysis are summarized.
