【摘要】 本文从构造地质学、地震学和地球动力学的角度出发,论述了青岛及邻区的地质构造背景,阐述了青岛马山—王哥庄断裂带的构造活动特征,分析了青岛地区的地震活动性.通过分析2003年6月和2004年11月的崂山震群活动特征,进一步确定了马山—王哥庄断裂带的构造活动性.受来自南黄海的区域构造应力作用,该断裂带尤其是其东南段表现出较强的构造活动性,具有引发有感乃至中等地震的可能性.更多还原

【Abstract】 According to the structure geology,seismology and geodynamics,this paper discuses the seismic and geological background of Qingdao and its adjacent areas,expounds the geological and structural characteristics of Mashan—Wanggezhuang Fracture zone in Qingdao.The seismic activity in the area is analyzed.Based on the analysis on two earthquake groups generated in Wanggezhuang Town,Mountain Laoshan separately in June of 2003 and November of 2004,the tectonic activity of Mashan—Wanggezhuang Fracture zone is determined.Affected by the regional tectonic stress field in South Yellow Sea area,the fracture zone mentioned above,especially its southeast segment,behaves more intensive tectonic activity,with ability to cause the felt-middle earthquake.更多还原
