【摘要】 利用新源单台记录到的2012年6月30日新源、和静MS6.6地震序列以及震前的数字地震波资料,分析地震前后尾波Q值的变化特征。结果表明,在地震前后Q值有明显变化,而随着强震后能量的释放,Q值趋于平缓。通过对Q值变化特征的研究,可以为地震预报工作提供可靠依据。更多还原

【Abstract】 Using earthquake sequence of Xinyuan,Hejing earthquake with MS6.6 and digital seismic data recorded by Xinyuan station,this paper analyzed characteristics of coda Q value before and after the earthquake.The results show: there is an obvious change before and after the earthquake,with energy release of strong earthquake,changing tendency of Q value becoming flat.Study on characteristic of Q value will provide reliable basis for earthquake prediction.更多还原
