- Abstract:
- In this paper,the result of the study about the aftershock-swarm of the MS6.4 earthquake occurred on June 3,2007 in Ning'er,Yunnan Province was given and the existence of both shear-wave splitting and the extensive dilatancy anisotropy in the upper crust of Ning'er region were recognized.The fast shear wave has two preponderant polarization-directions—NW140°and NW150°,which agree with the regional principal compressive stress.The delay time of the shear wave dynamically responds to the variation of stress field and increases before strong aftershocks.
