摘　　要：利用玉门5.9级地震震区临时台网和甘肃数字台网监测资料,用两种方法对地震序列进行了定位,并对结果的误差进行了分析。结果表明,利用“双差法”可以大大提高定位精度特别是震源深度的定位精度。The locating of the seismic sequence of Yumen earthquake,M =5.9 using two methods have been done using the data of the temporal network and the Gansu digital seismic network. And the locating error analysis have been studied. The results show that the locating precision obtained by hypoDD can be advanced greatly especially for the locations of the depths.
