南澎列岛及其附近海域、岛屿地震构造上属东南沿海泉州——汕头地震构造带东支的南段,近年来地震,地质和海洋部门很多学者和研究者对该地震构造带做了很多调查研究工作,使对该地震构造带的认识愈来愈深入。但上述研究大部分主要限于沿岸第四纪盆地及其附近地带,对海域内及岛屿上的地震地质特点论述不多,因此详细地研究该带在海域内和岛屿上的地震地质特点,对于深入了解东南沿海的地震构造,震源物理和地震活动,对于沿海国民经济建设都有重要意义。
In the southern part of the Nanpeng archipelago and its adjacent sea areas, the seismotectonics of the islands belongs to the southern segment of the east branch of the Quanzhou-Shantou seismic belt in the southeast coast. In recent years, many scholars and researchers in the seismological, geological and marine sectors have done a lot of investigations into the seismotectonic belt Research work has deepened the understanding of the earthquake zone. However, most of the above studies are mainly confined to the Quaternary basins along the coast and the surrounding areas. There are not many expositions on the seismic geologic features in the sea areas and on the islands. Therefore, the seismic geological features of the sea areas and the islands are studied in detail. Understanding the seismic structure, source physics and seismic activity of the southeast coast is of great significance to the economic construction of coastal areas.
