六十年代美、日、苏等国几乎同时开始海底地震仪器及海底地震的观测研究工作。七十年代初进入初步试验及实际观测研究阶段。八十年代达到大量推广应用及深入观测研究阶段。现已发展成为地震学的一个重要分支“海底地震学”。日本以很大的人力物力投入该项观测研究工作。海底地震学在美国已成为主要研究课题,苏联及其他欧洲国家也很重视这项研究工作。目前世界上至少有20多个研究组在
In the 1960s, the United States, Japan and the Soviet Union and other countries started the seabed seismic instruments and undersea earthquake observation and research work. The early seventies into the preliminary test and the actual observation of the research phase. Eighties to achieve a large number of promotion and application of in-depth observation and research phase. Has now developed into an important branch of seismology, “seabed seismology.” Japan invested a lot of manpower and resources in the observational work. Seabed seismology in the United States has become a major research topic, the Soviet Union and other European countries also attach great importance to this research. At present there are at least more than 20 research groups in the world
