The paper studies the shear wave splitting on the basis of the digital waveform of three seismic stations DJS, SZD and WUJ, which were set up after the Jiujiang-Ruichang MsS. 7 earthquake of November 26, 2005 around the epicenter site. The result shows that the time delays of slow wave of the DJS station, which is not far from the epicenter with the complex distribution of the faults nearby, are relatively larger and the polarization direction of fast wave is not concentrated; the predominant polarization direction of fast wave of WUJ station, with single fault distributed near there, has a difference of 35~ to the strike of the fault and is inconsistent with the direction of regional principal compressive stress. The predominant polarization direction of fast wave of SZI） station with no fault nearby is in accordance with regional principal compressive stress. There is no obviously regular relation between the delay time and the focal depth.[著者文摘]
