| 摘 要： | 台湾海峡７．３级地震发生在北东东向台湾西南分国地的北缘活动断裂带上，这里的地质构造复杂，断块差异性升降运动强烈，为台湾浅滩隆起与台湾西南断陷分国地的交替地段；也是深部布格重力异常带由北东东转折为北东向的交汇部位，地震等烈度线的轮廓形态大致反映出其发震构造的走向。

| Abstract: | A Ms=7.3 earthquake in southern Taiwan Strait occurred at the active fault zone of northern fring of southwest basin of Taiwan,which tends toward the NEE.The geological structure here is complicated and the differential elevated movement of block is very Strong,so that it became the alternating section between the upwarp of Taiwan shoal and the rift of southwest basin of Taiwan; and also the alternating part of deep Bouguer gravity anomaly zone which take a turn from NEE into NE.The outline of equal intensity curve of this earthquake may roughly reflect the strike of the seismogenic structure. |
