英文摘要	Traditional earthquake location methods usually need to pick first arrivals of signals, which have a low precision when these arrivals are unremarkable or submerged by strong noise. In this paper, we employ the 3-D varying-grid Gaussian beam migration imaging method to determine seismic source locations. We apply this method to deal with the synthetic seismograms and real seismic events in the Capital Circle region around Beijing to verify the validity of this method.
