摘    要:基于Sato单次散射模型,利用安徽省数字化测震台网2001年以来记录到的ML≥2.3级地震的波形资料,计算得到了安徽地区不同台站周围地壳介质的尾波Qc值,发现省内不同地区尾波Qc值存在着明显的差异,霍山地区尾波Qc值相对省内其余地区较低,拟合得到了安徽地区尾波Qc值与频率之间的依赖关系,为Qc=(104.9±36.4)...

关 键 词:尾波Qc值  Sato模型  震群序列  延续时间

Abstract:Based on digital waveform data of ML≥2.3 earthquakes recorded by Anhui digital seismic network,the Qc value of the medium below seismic stations in Anhui area is calculated using the Sato single scattering model.The results show that the Qc value is inhomogeneous and much lower in Huoshan area.The formula for the relationship between Qc value and frequency in Anhui area is determined using curve fitting,which isQc=(104.9±36.4)f~((0.85±0.08)).Particularly,the Qc value of Huoshan earthquake swarm sequences occurred from February to December of 2009 is calculated and analyzed, which shows significant difference between before and after the main shock.
Keywords:the Qc value of code wave  the Sato model  earthquake swarm sequences  duration
