通过漳州盆地的新生性、断裂活动性、晚第四纪地壳运动、盆地内部新构造差异活动和强震活动周期等初步探讨了该盆地的地震危险性。结果表明 ,该盆地晚更新世开始突破北东向断裂的限制 ,继续向南东方向发展 ;展布于盆地内部的北东、北西向断裂在晚更新世期间活动较为强烈 ;晚第四纪地壳升降运动频繁 ;盆地内部新构造差异活动强烈 ;最后一次历史强震距今已有 4 0 0a ,大大超过了该地区历史记录中 2 6 0a的强震活动最大间隔。因此 ,该盆地具有较大的地震危险性
The seismogenic hazard of the basin has been primarily discussed through the neogenesis of the Zhangzhou basin, the activity of the fault, the Late Quaternary crustal movement, the new tectonic dis- tribution in the basin and the period of strong earthquakes. The results show that the Late Pleistocene in the basin started to break the limitation of NE-trending faults and continued to develop in the south-east direction. The NE and NW-trending faults within the basin were more active during the Late Pleistocene. The Late Quaternary crust There are frequent new movements in the basin; the neotectonic difference in the interior of the basin is intense; the last strong earthquake has lasted 400a, far exceeding the maximum interval of strong earthquakes of 260a in the historical record of the area. Therefore, the basin has a greater seismic risk
