| 摘 要： | 基于Sato模型,采用2016年3月至2018年6月内蒙古东北部及临近地区发生的526次地震事件,挑选M_L≥2.0、记录清晰且信噪比较高的102次地震事件,拟合得到内蒙古东北部地区尾波Q值,得到Q_C(f)=(64.74±29.09)f(0.8925±0.0765);Q值与依赖指数η成反比,且该区北部Q值偏高,南部Q值偏低,可能与地质构造及地震活动性有关。

| Abstract: | Based on the Sato model, 102 earthquake events with ML ≥ 2.0 and waveform clear records and high signal-to-noise ratio were selected from 526 earthquake events in the northeast of Inner Mongolia and adjacent areas from March 2016 to June 2018. The results of fitting Q value of coda wave in the northeast of Inner Mongolia is QC( f )=(64.74 ± 29.09) f^(0.8925 ± 0.0765). The Q value is inversely proportional to the dependence index η, and the Q value in the north is higher and the Q value in the south is lower. May be related to tectonic and seismic activity. |
