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。
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.
