| 摘 要： | 本文用对应分析方法对秦岭北缘大断裂各段的断层气(水溶气)进行了分析,由此确定的该断裂地震危险段顺序为,贵德—循化段大于临潼—咸阳段,清水区在两者之间,天水—和政段大于眉县—兰田段。并进一步得出,贵德—循化段和清水区为强震危险区,而眉县—兰田段不会发生7级以上大震。

| Abstract: | This paper analyses the fault gases of each segment of large faults in the northern fringe of Qinling Mountain, determines the segment order of strong earthquake risk: the earthquake risk is stronger in the Guide-Xunhua segment than that in the Lintong-Xianyang segment; the earthquake risk in the Qingshui segment is between above-mentioned two segments; and the earthquake risk is stronger in the Tianshui-Hezheng segment than that in the Meixian-Lantian segment. The authors further determine that the Guide-Xunhua segment and Qingshui area are strong earthquake risk areas, and in the Meixian-Lantian segment there will not occur any earthquake (M≥7). |
