摘要
In this article,we have inverted local broadband waveform data to determine the foca1 mechanism of 2011 Anqing Ms4.8 earthquake.Our result shows that the best double couple solution of the Ms4.8 event is 16°,74° and 120° for strike,dip and rake angles respectively.The other nodal plane is 131°,33°,30°;the estimated focal depth is about 3km.The both strikes of the two nodal plane are significantly different with the strike of the Susong-Zongyang fault,which has a low level of seismic activity since Late Quaternary.This implies that this earthquake may not occur on the Susong-Zongyang fault,and we infer that a buried fault with strike of NNE may be the seismogenic structure of this event.
