《日本经济新闻》1980年9月16日刊登一篇文章,题为《高密度观测地震波——建设省土木研究所在几百米见方地面上安装十几台强震仪》,摘译如下:调查因地基和地形的差别,地震造成的晃动有什么不同,以有助于建筑物的耐震设计。为此,建设省的土木研究所决定从明年度开始执行“高密度强震观测计划”。在几 The Nihon Keizai Shimbun published an article on September 16, 1980 titled “High Density Observation Seismic Wave - The Institute of Civil Engineering of the Ministry of Construction installed more than a dozen of strongholds on a ground of several hundred meters and meters” as follows: Investigate the difference between the ground and topography, the shaking caused by the earthquake to help earthquake-resistant design of the building. To this end, the Civil Engineering Institute of the Ministry of Construction decided to implement the “High-Density Strong Earthquake Observation Program” from the next fiscal year. In a few
