摘要

选取广东省‘十五’数字地震台网2007年6～9月试运行以来记录到的32次地震事件,运用地震台网地震速报及地震编目使用的几种常规地震定位软件,并将其结果与‘九五’编目产出的结果进行了比较,结果表明:对于网内地震,单纯型定位法及HYPO2000程序的定位法结果稍优于Hyposat定位法;对于网缘地震,3种定位程序得到的结果相差不大。
In this paper,32 earthquake events recorded by Guangdong Province 10th Five-year Plan digital seismic network during Jun. -Sept. 2007 are selected and analyzed using several conventional earthquake location software adopted in seismic network earthquake prompt report and cataloging. And the results were compared with the 9th Five -year Plan cataloging output results. The results show that:for the net earthquakes,the results given by the simple positioning method and HYPO2000 positioning program are slightly better than that of Hyposat positioning method; for the net margin earthquakes,the difference of the positioning results given by the three kinds of programs is minor.
