| 摘 要： | 基于相对强度算法提出了一种量化地震活动状态变化的方法,数值试验表明,该方法可以综合反映地震活动在空间上和强度上的某些特征.应用该方法对华东地区(30°～37°N,114°～120°E)1970年以来地震活动情况进行了研究,结果表明:研究区内的4次中强地震都发生在地震活动状态的相似度曲线低值回升阶段;中强地震前2～3年的...

| Abstract: | A new method has been proposed to analyse quantitative changes of earthquake activities based on relative intensity(RI) algorithm.Numeric tests indicate that this method can reflect some characteristics of seismic activities on space and strength.This method is applied to investigate earthquake activities in east China area since 1970.The results demonstrate that 4 moderate earthquake events all occurred at the uplift stage of similarity curves of the regional earthquake activities.2~3 years before the mode... |
