银川地震台地震波记录特征
|
摘要
通过对银川台具有代表性的１００个典型地震记录图的震相分析，按震中位置不同分区展示了银川台地震波记录的“影区不影”、灵武地震方位异常，东北方向的近震ＰＮ波缺失以及极远震的ＳＮＫＳ波记录，文章还分区概述了银川台对全球不同地区发生的地震所记录的地震波的记录特征。
In this paper,by analysing the seismic phases of 100 typical and representative seismograms recorded at Yinchuan Seismostation,“Shadow zone has no shadow”of seismic wave records of Yinchuan Seismostation,directional abnormality of Lingwu Earthquake,lack of PN wave of near shocks along northeast direction and SNKS wave records of the farthest shocks are showed according to different divided regions and epicentral positions.And record features of earthquake waves of earthquakes occurred in different regions of the whole globe recorded at Yinchuan Seismostation are described roughly according to divided regions in this paper.
