Abstract：Marine seismic monitoring,one of the most important contents of earthquake prevention and disaster reduction,is a technical methodology to improve the positioning accuracy and monitoring capacity of earthquakes in the sea area,and can provide valuable basic information for basic geological research such as geotectonics and geodynamics.Based on the development status of marine seismic monitoring technology at home and abroad,by combining the technical characteristics of modern marine data buoys and submarine fiber-optic cables,this paper focuses on the marine seismic monitoring technology and method based on three-anchor large buoy platform.The study shows that it is more feasible and operable to construct the seismic monitoring system based on marine buoy platform,and it is more suitable to use three-anchor diameter large buoys as the"communication and electronic supply system".The research has also shown that the security of the marine seismic monitoring project is related to the stable operation of the entire system,and the safety and security measures for the connection between the"communication and electronic supply system"and the"seismic observation technology subsystem"should be paid special attention to.The quality assurance of the marine seismic monitoring project is related to the completion of the whole system.In the submarine installation of the"seismic observation technology subsystem",attention should be paid to the two important aspects of protection against ocean currents and earth coupling of seismic equipment.
