摘要
应用云南通海地磁台K≥6的磁暴数据,对云南省内M≥5.0地震发震时间关系进行统计分析发现:K≥7的大磁暴对云南省M≥5.0地震触发作用显著,且不同强度的磁暴对地震的触发作用有差异,磁暴强度增加,触发作用也增大。这一分析结果对云南地区5级以上地震发生时间的预测有一定的意义。
Based on the relative statistic analysis of the K≥6 magnetic data observed at the Tonghai station and the occurrence times of M≥5 earthquakes in Yunnan, it is found that the K≥7 magnetic storms obviously contribute to the occurrences of M≥5 earthquake in the area, and the trigger is different with various strength of magnetic storm, the stronger the strength, the lager the earthquake. The result has some realistic significance for the prediction of the occurrence time of M≥5 earthquake in Yunnan.
