摘要
利用大同台网1990~2000年的地震记录资料,系统地分析了大同地震序列尾波Q值随时间的变化,着重分析了尾波Q值在中强地震前的短期变化特征。结果表明,分频率的尾波Q值在几次中强地震前都不同程度出现了低值,并与大同震情"窗口"出现同步的异常。
Based on the seismic recording data of the Telemetric Seismic Network of Datong from 1990~2000, the variation characteristics of seismic code Q value of Datong earthquake sequence with time, especially the short-term variation characteristics before moderate strong earthquakes are systematically analyzed. The results indicate that the code Q value of earth frequency show low value before several moderate strong earthquakes and show the anomaly with Datong seismic condition "window" synchronously.
