根据近10多年来地球内部电磁性质及构造活动产生某些局部地磁异常的观测研究情况,国际大地测量和地球物理联合会于1979年12月召开的全体大会上决定把构造磁学作为一个重要问题加以讨论。进一步明确这一问题的意义,不仅在于解决现代地质学基本任务之一是建立地球的物理模型,而且在构造磁学用于可能解决破坏性地球物理现象的预报问题上(如强震发生、火山喷发、海啸侵袭及一些瞬时电磁现象等)更有实际的应用价值。会议议题中有长期变化异常及其与构造活动区和地壳垂直
According to the observation and study of some local geomagnetic anomalies caused by electromagnetic properties and tectonic activities in the past 10 years or so, the International Geodetic and Geophysical Union decided at the plenary meeting held in December 1979 to consider the construction of magnetism as an important issue Discuss it. The significance of further clarifying this issue lies not only in the resolution of one of the basic tasks of modern geology in establishing the physical model of the Earth but also in the application of the constructed magnetism to the prediction of possible devastating geophysical phenomena (such as strong earthquakes, volcanoes Eruption, tsunami invasion and some transient electromagnetic phenomena, etc.) more practical value. Long-term changes in the conference topics are anomalous and vertical to the tectonic activity zone and the crust
