摘要
利用χ2检验方法对我国大陆6级以上地震平静与7级以上地震发生之间的关系进行了统计检验,结果表明:6级以上地震平静与我国大陆地区发生7级以上地震的关系不显著。6级以上地震平静460天与其后1年2月内我国大陆及边境地区发生7级以上地震的关系显著。
Based on the statistic test of significance of x^2, analysis of relationship between quiescence of earthquakes with Ms ≥6 in Chinese mainland and occmrrnce of earthquakes with Ms ≥7 is conducted. The results show that the relationship between the quiescence of earthquakes with Ms≥6 in Chinese mainland and the occurrence of earthquakes with Ms ≥7 in Chinese mainland is not of significance, while the relationship between 460 days quiescence of earthquakes with Ms ≥6 in Chinese mainland and the occurrence of earthquakes with Ms ≥7 in Chinese mainland and its border region one year and two months after the 460 days quiescence is of significance.
