摘要
分析1988年库尔勒和阳霞台地震尾波资料发现,地方震尾波衰减系数α值、尾波持续时间比τ值,在中强震前确有异常显示。
Through the analysis of coda of earthquakes observed at Kuerle and Yangxia station in 1988, It is found that the attenuation coefficient a and the duration time of local earthquakes have obvious anomaly before moderate and strong earthquakes.
