| 摘 要： | 通过对1971年以来福建政和-海丰断裂带地震活动特征分析后认为：北东向的政和-海丰断裂带和次一级北西向的永安-晋江断裂带相互交汇,形成了4～5级中强地震反复发生的潜在震源区：在该断裂带主干上所发生的地震活动基本上具有前-主-余-震型和震群型的特点：在该断裂带主干上的M≥3．0以上的中等地震主要发生在北西向永安-晋江断裂的以南地区;该断裂带的地震活动在空间分布上是中段地震活动性强,北段地震活动性弱。

| Abstract: | Through analysis on characteristics of earthquake activities,it is considered that the primary cracking section of the northeast Zhenghe-Haifeng fault zone interacts with the secondary cracking section of the northwest Yongan-Jinjiang fault zone,and a potential source zone with frequent occurrence of medium and strong earthquakes has been formed. |
