Abstract:Using Three-component broadband digital waveform data from Hebei Digital Seismograph Net-work,we inversed the seismic moment tensor of Hebei Zhuolu M4.3 earthquake on September 6,2014 in time domain,obtain the optimum solution at the depth of 14km.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 strike-slip type which is consistent with the result from grid method.The seismogenic structure of the earth-quake is discussed combining with geological data and background tectonic of the Zhuolu area.
