黑龙江省有时会发生震源深度300-600 km的深源地震，且地震释放能量及有感范围均较大。该地区发生M > 6.0深源地震会产生较大社会影响，对于深源地震，快速准确地确定震源参数具有重要意义。利用黑龙江省测震台网自"十五"项目投入运行以来记录的31条深源地震数据，采用LocSAT和HypoSAT定位方法进行重新定位，将定位结果与中国地震台网中心统一编目给出的目录数据进行对比，寻求更加适用该区深震的定位方法。分析表明，对于黑龙江省测震台网记录的东北地区深源地震，使用HypoSAT方法进行定位结果优于LocSAT定位方法。
In Heilongjiang Province, sometimes a deep-source earthquake with a depth of 300 km to 600 km will occur, and the energy released by the earthquake and the range of sense are large. The occurrence of M >6.0 deep-source earthquake in this region will have a great social impact, which is of great significance for the rapid and accurate determination of the seismic parameters of deep-source earthquakes. The 31 deep-source seismic data recorded by heilongjiang seismographic network since the tenth five-year plan project was put into operation were relocated by using LocSAT and HypoSAT positioning methods, and the positioning results were compared with the catalogue data given by China Earthquake Networks Center to find a more suitable location method for deep earthquake in this area. The analysis shows that the HypoSAT method is superior to the LocSAT method in locating the deep-source earthquakes recorded in Heilongjiang Province.
