摘要
应用成都数字遥测地震台网数据 ,通过对震中距大于 30 0千米的 5 5次地震重新定位 ,对比研究成都数字遥测地震台网数据处理软件提供的几种地震定位程序以及原模拟台网使用的地震定位程序 ,初步认为 :震中距在 30 0千米 <Δ≤ 10°时 ,Genetic、Gerlor -P、Gelor-I程序优于Front和loc2 12程序 ,而Telloc、loc312程序基本不能用 ;震中距在 10° <Δ≤ 2 0°和 2 0° <Δ≤ 5 0°时的地震定位 ,Front优于loc2 12程序 ,而Telloc程序不能用。
By comparing 55 seismic events re-locating results,in which the epicenter distances of them are greater than 300 kilometers,from the telemetering digital seismograph recordings with the results of same earthquakes from the simulant seismograph recordings,we find that the locating programs such as Genetic,Gerlor-P and Gelor-I are better than Front and Loc212 programs when the epicenter distance is less than 300 kilometers.The Telloc,Loc312 locating programs are no use.The locating program Front is better than Loc212 when the epicenter distances are from 10 degree to 50 degree.
