国际海洋地震观测最新进展和我国海洋地震观测发展探讨
|
摘要
海洋地震观测是全球地震观测的一个重要组成部分。论述了国际海洋地震观测的最新进展及我国海洋地震观测的发展情况:目前全球海洋地震观测已进入深海海底长期定点实时观测阶段,美国、加拿大、日本和我国台湾地区的几个环太平洋大型海底科学观测项目正在安装调试,日本还启动了海底发震带的钻探及钻孔观测以研究海底动力学过程。我国也断续开展了一些海洋地震观测试验,但目前长期海洋地震观测基本处于空白。认为,海洋地震观测技术门槛高,系统性强,但近年来在美日等国已趋于成熟,正在推广实用,未来防震减灾应用广泛,需要关注。
Marine seismic observation is an important component of global seismic observation.The progress of international marine seismic observation and development of domestic marine seismic observation are discussed in this paper.At present,the global marine seismic observation has entered the stage of long-term fixed-point real-time observation at sea bottom,and several large circum-pacific projects of sea bottom scientific observation of US,Canada,Japan and Taiwan region of China are underinstallating.In addition,Japan starts drilling and borehole observation on seafloor seismogenic zone to study the process of submarine dynamics.China also carried out some marine seismic observation experiments,but long-term marine seismic observation has never been planned yet.The authors think that marine seismic observation is a hi-tech system,but it has come close to be mature and practical in developed countries such as the U.S.and Japan.It should arouse our attention.
