摘要

///Using seismic waveform data recorded at station Yingkou (YK) of Liaoning Telemetry Digital Seismic Network, this paper studied the characteristics of shear-wave splitting before and after the Xiuyan M_S5.9 (M_L5.3) earthquake on November 29, 1999, with the SAM method (Gao et al). The result shows that predominant polarization of fast shear-waves at YK is in direction of ENE-WSW, consistent with the direction of regional principal compressive stress and also consistent with the direction of regional tectonic stress field in North China.
