摘要
１９８４年５月２１日的南黄海地震发生在海里，地震观测台站都偏在震中的西侧，距离最近的南通台和崇明台也在１００ｋｍ左右，给地震的精细测定带来了困难。用现有测震方法，得到的南黄海地震序列观测报告，震中分布比较离散。本文在进一步发展了无走时表定位法和相对定位法的基础上，对南黄海地震序列中的３级以上地震的时空参数作了重新测定和分析，取得了较精细的结果。
It is unable to fix up temporary observing stAtion for the earthquake occurring in the South Yellow Sea on May 21, 1984. The exiting seismic stations are all located on the west of this event far from the epicenter, the distance between the epicenter and the nearest stations, Nantong station and Chongming station, are also about 100 km, this makes the accurate locating difficult. By using routine locating method, epicenters of the South Yellow Sea earthquake sequence in Bulletin of Seismological observations originally published by Shanghai telemetering seismic network are more dispersed. But accurate locating the spatial and temporal seismic parametets of the earthquake sequence is extremely important, a lot of further work are finished on the basis of it. So in this paper, on the basis of developing the no-travel-time-table method and relative locating method, the authors locate and analyze the earthquake sequence again for the magnitudes to greater than 3, the more accurate result is obtained.
