日本自1964年新潟地震后,从1965年开始提出国家规模的地震预报计划,到1978年为止已执行了三次预报计划。综观日本历次预报计划的内容,结合这次的实地考察,并通过与日本有关地震学者的多方面交谈,对日本目前以及未来进行地震预报的基本想法和做法,有了较系统的了解。概括起来,可分别从图(1)和图(2)的纵横两个方面加以阐明。 Japan has proposed a national-scale earthquake prediction program since 1965 after the Niigata earthquake in 1964. By 1978, three forecast programs have been implemented. Based on the contents of the previous forecast plans in Japan, combined with this field visit, and through various conversations with Japanese seismologists, we have a more systematic understanding of the basic ideas and practices for earthquake prediction in Japan and in the future. To summarize, we can clarify the two aspects of aspect (1) and aspect (2) respectively.
