摘要
Using the epicenter trajectory which is constructed by the arrival time difference of two seismic stations approximately meets hyperbolic equation,combined with the azimuth and epicenter distance determined by the single station,we used technical ideas of the epicenter location restricted by Voronoi diagram so as to realize that the accuracy of earthquake location gradually increase based on the 71 earthquake waveforms recorded by Shandong Seismic Network from 2009 to 2011,.Compared with the location of the epicenter in observation report of Shandong Seismic Network,the results showed that the average error of location respectively determined by a single station,two stations and three stations was 18.3 km,16.6km,and 10.7 km.
