【摘要】 以汶川地震为例,统计分析2008年5月12日—2009年9月30日5级以上强余震与引潮力的关系,发现平行断层方向的线应变引潮力峰(谷)值时间与汶川地震及强余震发震时间的对应关系较好,且其对应程度与断层性质有关。综合分析认为,引潮力可能是地震的诱发因素之一。更多还原

【Abstract】 Wenchuan earthquake is taken as example, relation between strong aftershock above M 5.0 of wenchuan earthquake and tidal force has been counted and analyzed. The results show occurrence time of wave crest/trough on linear strain of tidal force paralleled fault is corre-sponded with Wenchuan earthquake and strong aftershocks, and correspondence is related with fault character. Composite analyses indicate tidal force maybe is one of factors drew in earthquake occurrence.更多还原
