摘要
利用中法合作建立的微震数字地震台的资料研究了海原西断层松山附近地区的微震尾波的衰减特征．计算了１７０次地震的７个频带的尾波Ｑｃ值，得出该地区尾波衰减可用Ｑｃ＝５２ｆ１．０９表示，表明这个地区是构造活动水平较高的地区．
Using the data of the digital network monitoring micro earthquake cooperatively set up by China and France, the attenuation characteristics of the Q value of coda of microearthquakes in the area along western Haiyuan fault near Songshan have been studied. The coda Q c values on 7 frequency bands of 170 earthquakes have been calculated. The coda attenuation in the area can be represented by Q c=52f 1.09 . It is shown that this area is a highly tectonic activity area.
