CHARACTERISTICS OF EARTHQUAKE ACTIVITY IN QINGDAO AND ITS ADJACENT REGION

摘要: 对青岛及邻近地区的地震地质背景和地震活动情况进行了分析, 并结合本区的小震综合机制解的特点, 分析了P、T轴时序变化与邻区地震活动之间关系, 发现中强地震的发生可导致研究区域内P、T轴方位的变化。P、T轴方位变化的时间较为同步, 而P轴方位变化幅度更为明显。Abstract: The seismogeological background and seismic activity in Qingdao and its adjacent area are analyzed.Combined the focal mechanism of small earthquakes in the region, the relation between time sequence variation of P and T axes and earthquake activities in adjacent area is studied.The results show that the occurrence of strong earthquakes can cause the variation of P and T axis direction.The variation of P and T axes is synchronous, but the magnitude of P axis change is more obvious.
