近年来,日本在国际上积极参加国际地球观测年、国际地球内部开发计划、地球大气开发计划、世界磁测等各种国际合作观测工作,在国内大力开展地球物理、地震地质、地球化学、大地测量、日地空间物理等方面综合性研究,重视观测技术、观测和观测资料收集处理系统的研究,因此,日本地震学研究在观测手段、测定方法、观测精度,以及在理论上应用上都有了较大的发展。日本地震学中的研究课题包括以下几个方面。 In recent years, Japan has actively participated in various international cooperation and observational events such as the International Earth Observation Year, the International Earth’s Internal Development Plan, the Earth’s Atmosphere Development Plan, and the World Magnetic Survey. In the country, Japan vigorously conducts earth observation, geology, geochemistry, Measurement, space science and other aspects of comprehensive research, emphasis on observation technology, observation and observation data collection and processing system research, therefore, the Japanese seismological studies in the observation methods, measurement methods, observation accuracy, and in theory have A larger development. Seismology in Japan research topics include the following aspects.
