【摘要】 应用广东数字遥测地震台网数据,通过对广东省周边50 km以外的62次地震重新定位,对比研究广东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,初步认为:中国东南部、西北部地区及国外距广东地区较近的位于中国东南方向的印尼、日本等地区的地震,3种定位方法均可对其进行定位;而分布在国外较远地区的地震,用Hyposat及locSAT定位程序尚可,且locSAT优于Hyposat定位程序,而单纯型定位程序几乎不能用。更多还原

【Abstract】 Based seismic waveform data of Guangdong digital network,through relocating of 62 distant earthquakes over 50km to Guangdong province,the three earthquake locating methods used in Guangdong digital seismic network are contrasted with each other.The result shows that to the earthquakes in east-southern China,west-northern China,and earthquakes not far from Guangdong area in Indonesia and Japan,all the three earthquake location methods are effective.As to the earthquakes far from China in abroad,the Hyposat method and locSAT method are also effective,but the simplex location method is out of action.更多还原
