摘　　要：利用台网测震观测资料集中的优势，通过一些震例，探讨了对震级偏小、震相清晰度差的地震，利用 Ｓｇ 波到时，求出震中距，解决定位的方法。Making use of superiority of concentrated seismolographic rec ord in seismic station network and based on several earthquake examples, the method to determine epicenter and to l ocate have been obtained by means of S g wave arrival time for some earthquakes with small magnitude and un clear initial motion
