摘要
应用磁暴月相二倍法对1998年5月~2001年1月期间全球发生的MS≥7.5大地震进行研究.在16次大地震中发生于磁暴月相二倍法得出的计算发震日期(±5天)有13次;在15次计算发震日期中有11次对应MS≥7.5大地震,2次对应7.0≤MS≤7.4地震.研究表明K指数大的起倍磁暴日与MS≥7.8特大地震的发生有较好的相关性,发生在月相的磁暴与MS≥7.5大地震相关关系较好.
From May, 1998 to January, 2001, there were 16 large earthquakes (MS≥7.5) over the world. Based on the twotime method of magnetic storm related to lunar phase,15 earthquake corresponding time intervals (±5 days) can be computed, and among them 13 occurred in 11 computed time intervals.Meanwhile,other 2 computed time intervals,correspond to 2 earthquakes (7.0≤MS≤7.4).The research result shows that the first magnetic storm with large storm index (K) correlate to the occurrence of M≥7.8 large earthquake,and the magnetic storms occurred in the lunar phase demonstrate good correlation to the M≥7.5 large earthquakes.
