据日本《科学新闻》1980年8月15日报道,日本科技厅1980年度地震方面特定研究实施计划是菲律宾板块北端有关大地构造的综合研究,目的是搞清楚其周围地区的地震机制。第一期以三年时间根据伊豆半岛、相模湾及骏河湾地区地壳构造、构造运动及地壳活动等的调查,结合已有知识,综合地阐明该地区地震机制,同时研究开发用于该地区海域的观测系统等地震预报方面的必要技术。关于地壳构造,为了搞清楚板块潜入状
According to Japan’s Science News reported on August 15, 1980, Japan’s Science and Technology Agency’s 1980 Earthquake Specific Research Implementation Plan is a comprehensive study of the tectonics at the northern end of the Philippines Plate in order to clarify the seismic mechanisms in the surrounding areas. Based on the investigation of the crustal structure, tectonic movement and crustal activity in the Izu Peninsula, Sagami Bay and Suruga Bay areas in the first phase, combining with the existing knowledge, we comprehensively clarify the earthquake mechanism in this area, and at the same time, research and development for the area Sea area observation system and other seismic prediction aspects of the necessary technologies. On the crustal structure, in order to find out the submerged plate
