1976年和林格尔6.3级地震前后震兆特征分析
|
摘要
从时空变化特征、震源参数、地震波谱特征、b值、Vp Vs、Q值、持续时间衰减比、Ap As等方面对1976年 4月 6日和林格尔 6 3级地震进行了较为全面的分析 ,着重分析了地震前后 2年左右出现的运动学和动力学变化特征 ,以提取和林格尔 6 3级地震的短临信息。分析后认为此次地震出现的震兆特征与包头 6 4级地震、张北 6 2级地震某些方面有相似处 ,对探讨分析未来阴山、燕山地震带浅源中强震的孕育过程及提取临震信息 ,具有参考意义
A relatively overall analysis on the Ms 6 3 Holinger earthquake on April 6,1976 is made from time-space variation,source parameters,spectral features,b value,Vp/Vs ratio,Q value,T H/T V and Ap/As,stressing variation characteristics of kinematics and dynamics about 2 years before and after the earthquake in order to extract short-impending information about the Ms 6 3 Holinger earthquake.The authors think that seismic precursor features for the Holinger earthquake were similar to ones of the Ms 6 4 Zhangbei earthquake in some ways,which has reference significance for studying the seismogenic process and extracting impending information of future shallow-focus middle and strong earthquakes in the Yinshan and Yanshan seismic zones.
