摘要
选取2001年1月至2011年12月山西地震台网记录的ML≥2.0地震的数字地震波资料,运用单次散射Aki模型,计算得到山西地区尾波Q值,拟合Q值对频率的依赖关系。其中,右玉、代县、夏县、东山4个地震台站属于低Q值、高η值,为特质的构造运动活跃地区的尾波性质。
Based on the Aki single scatter model, using digital wave data of earthquakes with ML ~〉 2. 0 from January,2001 to December, 2011 ,recorded by Shanxi Seismic Network, the Q values of coda wave in Shanxi region are calculated and the relationship between Q value and frequency is figured out by fitting . Four seismological stations, Youyu, Daixian, Xiaxian, Dongshan, where Q values are low and η value are high, which mean that tectonic movement in those areas are active.
