摘要
利用山东数字地震台网和青岛数字地震台网的地震波形资料,基于单次散射模型的尾波小波包分析方法,计算了青岛地区4个台站附近的尾波Q值,拟合得到青岛地区及附近海域尾波Q值随频率的变化关系为:Q=123.5×f0.9;并对2003年6月青岛市王哥庄的4级震群序列的Q值进行计算分析,结果表明,在震群期间Q值变化不大。
Based on seismic waveform data of digital seismic networks of Shandong and Qingdao, the Q values of coda wave of the area around 4 seismic stations of Qingdao are calculated by using analysis method of wavelet package on single scattering model. The variation relationship Q-values with frequency of coda wave （Q） in Qingdao and its adjacent see area is obtained by fitting, be ing. Also, the Q-value for Wanggezhuang M4.0 earthquake swarm sequentze in 2003 June in Qingdao city is also calculated and analyzed, indicating that the Q-values did not change much during the earthquake swarm.
