Based on the broadband waveforms recorded by Xinjiang Digital Seismic Networks,we inversed the focal mechanism solutions of the Aketao M_S6.7 main shock,foreshock and M_S ≥ 3.6 aftershocks by using CAP method. The results shows that the focal mechanism of the M_S6.7 strong earthquake had the nodal plane Ⅰ with strike 20°/dip 69°/rake -10° and the nodal plane Ⅱ with strike 114°/dip 81°/rake -159°. Combining with the seismo-tectonic background of the seismic area,nodal plane Ⅱ was identified to be the seismogenic fault plane of the main shock. The direction of P-axis for the main shock is 339°,which is close to the NW,preferred direction of the P-axis of historical earthquakes in this area. The focal mechanism solution of M_S4.8 foreshock is in high consistency with main shock. About six aftershocks are strike-slip type earthquakes,three aftershocks are thrust type earthquakes,one aftershock is normal type earthquake,and one aftershock is hybrid type earthquake. The P-axis of most earthquakes in the sequence yields the NW direction. The focal depth of this M_S6.7 earthquake sequence distributed at 6~16km,and most of the earthquakes occurred within the depth range at 9~13km,which is close to the focal depth of 10km of mainshock we calculated. Finally,we conducted a preliminary analysis on the relationship between the strong earthquakes in Hindu Kush Pamir region and this Aketao 6.7 earthquake.
