山西太原东山地震台附近地区地震尾波Q_c值变化特征研究
Study on Variation Characteristics of Seismic Coda Wave Q_c in Area Around Dongshan Seismic Station,Shanxi
【摘要】 采用Aki单次散射模型,用太原东山地震台记录到的ML2.0~5.0地震,计算得到Qc值随频率的变化结果。得出,随着尾波窗长增大,平均采样体深度增加,Q0值增大,η值减小。当尾波窗长取20 s时,Q0值为70.1,η值为1.03,是东山台附近地区最佳的研究结果。
【Abstract】 Based on earthquakes of ML 2.0-5.0,recorded by Dongshan Seismic Station,Taiyuan,and Aki single dispersion model,Qc varied with frequency is calculated.The result shows that with the increasing of window width of coda wave,the average deepness of sampled body will increase,meanwhile,Q0 increases and η decreases.When the window width of coda wave is 20 s,Q0 is 70.1 and η is 1.03,which is the optimal research result for area around Dongshan Seismic Station,Shanxi.
