Abstract: The project of the “Research on Key Technologies of Seismic Zoning in Sea Areas” supported by the National Key R&D Program of China has been implemented for three years and has entered the final stage of the project, and the research has formed the method and technical system of seismic zoning in sea area. The research results will provide technical support for the ongoing compilation of the China seismic zoning map in sea area. The basis and existing problems of seismic zoning in the sea area were analyzed and discussed, and the main research achievements and progress were introduced and analyzed in combination with the key scientific and technical issues concerned, including fault activity detection and seismic structure in the sea area, earthquake catalogue and seismic activity characteristics in China sea and adjacent areas, ground motion characteristics and attenuation relation in the sea area, site conditions and influence on ground motion in the sea area, and methods and techniques for compiling seismic zoning maps in the sea area, etc. A series of related maps, databases and computing software programs were developed, including the active tectonics framework maps of the eastern and southern seas of China and seismic tectonics maps of three typical China sea areas (located in the Yellow Sea, Taiwan Strait and South China Sea), the unified earthquake catalogue in China sea area and adjacent areas, the map of potential seismic source zone in China sea area and its comparison scheme considering uncertainty, and the seismic hazard analysis software program considering the three-dimensional potential seismic source model. The research project developed a seismic tectonics model of subduction zone in China sea area and adjacent area, a ground motion attenuation relationship for intraplate earthquakes in the subduction zones of the South China Sea based on strong motion observation records and seismic simulation data, and long-period ground motion attenuation relationships for interface and intraslab earthquakes in subduction zone using strong-motion acceleration records combined with broadband velocity records, and proposed a site classification method and corresponding ground motion adjustment scheme for continental shelf based on the site overlaying depth and the equivalent shear wave velocity of soil layers. The principles, technical requirements, and technical methods for the compilation of seismic zoning maps in the sea area were put forward, the first draft of the Technical Regulations for compilating seismic zoning maps in the sea area was completed, and the compilation of the seismic zoning maps of three typical China sea areas was basically completed.
