| 摘 要： | 上海市地震局设计、建设的中国第1个真正意义上的海洋深井地震观测台位于东海石油平台上,井深780 m,安装2套JDF-1型地震计进行观测。通过对陆域地震台站记录的大地震进行分析比较、方位校准,采用单台地震分析方法,确定2009年5月—2011年6月记录到的136个地震参数,总结海域地震波形特征。结果表明,该海域地震活动性特征与当地地质构造一致。

| Abstract: | Bajiaoting, the first authentic ocean deep well seismic station, designed and constructed by Shanghai Earthquake Agency, is located in the East China Sea Oil platform, with a well depth of 780 km. And two sets of seismometer JDF-1 were installed on the bottom of the well. After comparing the position results of those great earthquakes that can be recorded simultaneously by the land seismic stations and Bajiaoting, the azimuth was calibrated. Then 136 earthquakes, which took place during the period from May 2009 to June 2011, were determined by single station position method and the waveform characteristics of the sea area earthquakes were summarized. It is certifed that the seismic activity of the sea area is consistent with the local geological structure. |
