【摘要】 通过对1971年以来福建政和-海丰断裂地震活动特征分析,认为政和-海丰断裂的地震活动是:在主体北东向政和-海丰断裂带和次级北西向永安-晋江断裂带相互交汇的构造格局下,形成了4～5级中强地震反复发生的潜在震源区。更多还原

【Abstract】 Through the characteristics analysis on the earthquake activity of Zhenghe-Haifeng fault zone,it is found that under the interacting structure between the primary cracking section of Zhenghe-Haifeng fault,which is in northeast orientation,and secondary cracking section of Yongan-Jinjiang,which is towards the northwest,the potential earthquake source of fre- quent occurrence at medium and strong level has been formed.更多还原
