国际大地测量与地球物理学联合会和国际地磁学与高层大气物理协会(IUGG/IAGA)第十七届全会于1979年12月在澳大利亚堪培拉举行。会上宣读的震磁关系研究方面的论文共十五篇。其中七篇直接涉及到地震的地磁前兆问题;三篇讨论了地磁长期变化异常与地震活动性问题;二篇是讨论岩矿的压磁效应的,关于分析方法和观测干扰方面的各一篇。日本东京大学应用物理系力武常次从1976年以来一直在伊豆半岛进行地磁场的加强观测。这期间在距台网三十公里范围内,共发生 IUGG and the 17th Plenary of the International Geomagnetic and Atmospheric Physics Association (IUGG / IAGA) were held in Canberra, Australia, in December 1979. A total of 15 papers on the study of the relationship between magnetism and magnetism were presented at the conference. Seven of them are directly related to the geomagnetic precursors of earthquakes; the third one discusses the long-term changes in geomagnetic anomalies and seismicity; the second one deals with the piezomagnetic effects of rock and mine, each in terms of analytical methods and observed interferences. Department of Applied Physics, University of Tokyo, Japan Wu always performed intensive observations of the geomagnetic field in the Izu Peninsula since 1976. During this period within thirty kilometers from the network, a total of occurred
