摘要
对山东地区胶东、沂沭、鲁西南等各分区小区域综合震源机制进行了计算分析,结合以往的工作结果,研究了山东区域背景应力场方向的总体特征和各分区主压和主张应力轴方向的动态变化,简单分析了应力场方向动态变化与本区中强地震的可能关系。
The comprehensive focal mechanism solutions in each subregion of Shandong area, such as Jiaodong, Yishu Southeast Shandong region, are analyzed. Combined with some previous results, the characteristics of stress field direction in Shandong area and the variation in the directions of principal tensional and compressive stress axis are studied, and the relation between the variation of stress field direction and local moderate strong earthquakes are also studied.
