摘要

这里主要分析首都圈及周围地区地磁垂直分量Z等变线变化与该区1～2年尺度中强地震的关系。经过分析得出:正常情况下年变线分布均匀,在首都圈及邻近地区较强地震发生前1～2年内出现等变线密集区域,未来地震就发生在区域的边缘,特别是等变线长轴所指方向的活动构造带上。
In this article,the relationship between the variation of magnetic isoporic lines and moderately strong earthquake activity in 1~2 year scale in Beijing and its neighboring area is mainly analyzes. The conclusion is that the distribution of magnetic isoporic lines is homogeneous under the normal condition,while the magnetic isoporic lines become dense about 1~2 years before the moderately strong earthquakes in Beijing and its neighboring area. The earthquakes would occur on the edge of this area,especially the active tectonic zone which pointed by the macroaxis of the magnetic isoporic lines.
