| 摘 要： | 在北东东向分布的华南地震带内,从巴士海峡到闽粤赣三省交界有呈北西向分布的地震密集带。它与北西向分布的巴士系断裂构造相一致。此组构造与华南地区其他北西向构造的重要区别在于,它起自菲律宾海板块的边缘,其动力主要来自该板块向欧亚板块不均匀的推挤作用。巴士系构造是华南地区新构造活动性最强的构造,沿着此组断裂曾有过大量强烈的地震活(?),包括6级、7级和8级地震。在未来10年内,此带的强震活动有逼近粤东、闽南沿海地区的趋势。

| Abstract: | In the South China seismic belt of NEE, there is a seismic closely spaced belt which distributed along the direction of NW in the place from Bashi Straits to the area where three provinces meet (Fujian, Guangdong and Jiangxi ) . The offset structure in the belt is in consistent with thatin Bashi system of NW. The important difference between this structure and other structutes of NW in South China area is that the former starts from the edge of Philippine sea plate and its force comes from uneven push of its plate to Eurasia plate. The motion in the structure of Bashi system is the most strongest during the neotectonics in South China area. Along this fault, there are many strong earthquakes, including earthquakes of Ms= 6 , 7 and 8. But in the coming decade, it is possible for the strong earthquakes will occur in. the coastal areas of east part in Guangdong and south part in Fujian. |
