| 摘 要： | In this article,we use the CAP method to invert the focal mechanism of Xinyuan-Hejing M S6. 6 earthquake on June 30,2012. Our result shows that the best double couple solution of the M S6. 6 event is 299°,68° and 164° for strike,dip and rake angles respectively. The other nodal plane is 35°,75° and 23°. The azimuth and dip angle of the P-axis are 166°and 5°,those of the T-axis are 258° and 26°. The moment magnitude is 6. 3. The estimated focal depth is about 21 km. The predominant rupture direction of this seismic sequence is NWW. The dip angles are between 60° and 90°. The rake angles are in the majority of ± 180°± 30°. The predominant strike of the azimuthal angle of the P-axis is near NS and T-axis is near EW. Preliminary analysis indicates that nodal plane I is the seismogenic fault,which is a NWW-trending,nearly upright left-lateral strike-slip fault.The displacement property,the principal compressive stress of this M S6. 6 earthquake and the P-axis preponderant orientation of this seismic sequence agree with the characteristics of the tectonic stress field of the focal area and its surroundings.
