为观测地壳深部区域性波速变化,研究地壳深部波速变异与地震活动的相关性,探索地壳深部地震预报前兆信息及其技术指标,国家地震局地球物理勘探大队计划从1981年起至1983年每年在渤海海湾定期定点进行海中爆炸。 1981年8月18、19日国家地震局地球物理勘探大队完成了我国首次海上爆炸试验。他们以52台DCJ-1型低频磁带地震仪布置在南堡—赤城—康保的
In order to observe the regional wave velocity changes in the deep crust and to study the correlation between the velocity variations of the deep crust and the seismic activity and to explore the precursory information and its technical indicators of the deep crustal seismic prediction. The geophysical prospecting brigade of the State Seismological Bureau plans from 1981 to 1983 Bohai Bay regularly sentinel explosion. August 18, 1981 August 19, the State Seismological Bureau of Geophysical Exploration Brigade completed the first marine explosion test in China. They are equipped with 52 DCJ-1 low-frequency tape seismographs in Nanpu - Chicheng - Kangbao
