摘要

在收集整理全球大震数据目录资料的基础上,利用贵阳地磁台地磁报告分析资料和FHD数字化磁力仪记录资料绘制图,统计分析了磁情指数K、磁暴与地震的关系,认为K指数<5时,磁暴次数少,地震多;反之,K指数≥5时,磁暴次数多,地震发生的次数少。根据有关专家研究统计对比模拟记录与数字化记录,两种仪器的观测记录资料基本一致。
Based on the data of the world large earthquakes,the geomagnetic report and the chart drawing by the FHD digital magnetometer,the relationship between the magnetic index K,the magnetic storms and the earthquakes is analyzed.The paper discussed a rule that when index K<5,the possibility of magnetic storms’ happening reduced;whereas,the index K≥5,the possibility of magnetic storms’ happening increased.According to the professors’ study on the contrast between the simulative records and the digital records,the data recorded by the two different magnetometers are basically consistent.
