| 摘 要： | ＮＥ、ＮＷ 向断裂是青岛及其邻区两组重要的区域性断裂构造。通过野外地质和地貌观察，依据所测的地震活动和断裂活动的绝对年龄，认为青岛地区ＮＥ向断裂自晚更新—全新世以来处于相对稳定的阶段。并根据ＮＷ 向断裂对海岸线方向、海底地貌，特别是ＮＷ 向断裂对地震的控制作用，认为青岛及其邻区ＮＷ 向断裂是一组区域性活动断裂。鳌山卫—即墨微震带是ＮＷ 向断裂的现代活动性的表现。在地震监测工作中应加强对ＮＷ 向断裂活动性的监测与研究。

| Abstract: | NE and NW faults are two major regional faults in the Qingdao area and its neighbourhood. Based on field work, geographic feature, earthquake records and faults forming chronology, the NE faults in the Qingdao area have been relatively stable since the Q 3~Q 4. The coast line direction and geographic shape of the sea bottom, especially the earthquakes are controlled by the NW faults. Therefore, the NW faults in the Qingdao area and its neighbourhood are active and regional. Their present activity mainly occurs along the Aoshanwei Jino weak belt. More attention should be paid to the activity of the NW faults in earthquake prediction in this area. |
