【摘要】 使用河北省遥测台网记录的三分量宽频带数字波形资料,在时间域反演2014年9月6日河北涿鹿M4.3地震的矩张量解,深度14km时得到最佳解,Variance（VR）为92.2、Double-couple（Pdc）值为88、Compensation linear vector dipole（CLVD）值为12,Residual/double-couple（RES/Pdc）达到9.54×10^-12,震源机制解呈右旋走滑,与格点尝试法计算结果一致,文章结合涿鹿地区的地质资料和构造背景对发震断层进行了讨论。更多还原

【Abstract】 Using Three-component broadband digital waveform data from Hebei Digital Seismograph Network,we inversed the seismic moment tensor of Hebei Zhuolu M4.3earthquake on September 6,2014 in time domain,obtain the optimum solution at the depth of 14 km.The results show that the Variance（VR）is 92.2,the Double-couple（Pdc）value is 88,the Compensation linear vector dipole（CLVD）is 12 and the Residual/double-couple（RES/Pdc）is 9.54×10^-12.The focal mechanism solution is of right-lateral strikeslip type which is consistent with the result from grid method.The seismogenic structure of the earthquake is discussed combining with geological data and background tectonic of the Zhuolu area.更多还原
