本文讨论了广西海岸带的新构造活动特征与地震的关系,认为,1.新生代以来,北西向和北东向断裂所围限的断块间的差异活动,控制着区内地质和地貌的发育。与北东向断裂相比较,北西向断裂具有较新、活动性较强的特点;2.地震主要分布在地貌反差较大的盆地边缘和两组断裂的交汇部位;3.全新世以来,断块之间在垂向上表现为整体抬升,水平方向上的活动性减弱,因此区内不会有较大地震发生。
This paper discusses the relationship between the tectonic features of the new tectonic movement of Guangxi coast and earthquakes and argues that since the Cenozoic, the differential activities between fault blocks limited by NW and NE faults control the geology and geomorphology of the area development. Compared with the NE-trending faults, the NW-trending faults are relatively new and highly active. 2. The earthquakes are mainly distributed at the margin of the basin with contrasting geomorphic features and the intersections of two faults. 3. Since the Holocene, The blocks are vertically uplifted and the activities in the horizontal direction are weakened, so that no major earthquakes will occur in the area.
