福建省东部紧连西太平洋地震带,历史上曾发生过多次强震,震级最大达8级,近来弱震活动也很频繁。这些地震绝大多数发生在福建东南部沿海一带,尤以近岸海域地区最甚。它们多沿活动断裂带分布,与第四纪以来,特别是现今的地壳活动密切相关。本文就近岸海域断裂的存在、基本特征及其与地震的关系,进行初步探讨。 Fujian Province, east of the Western Pacific seismic belt, the history of many strong earthquakes have occurred, the magnitude up to 8, the recent weak earthquake activity is also frequent. The vast majority of these earthquakes occurred in the coastal area of ​​southeastern Fujian, especially in the coastal areas. They are mostly distributed along active fault zones, which are closely related to the crustal activity since Quaternary, especially nowadays. In this paper, the existence of offshore faults, the basic characteristics and its relationship with the earthquake, to conduct a preliminary discussion.
