Abstract：The 667 earthquakes occurred in Fujian Xianyou from August 4,2010 to April 24,2013. The largest earthquake is ML4.1 on April 15 , 2012. In this paper, the focal mechanism solutions of the ML4.1 Xianyou earthquake on April 15, 2012 and ML3.8 Xianyou earthquake on November 25, 2012 are calculated by using the seismic moment tensor inverse method. The results show that the focal faults of the two earthquakes are strike slip faults with the fault strike to the north west and the principal compressive stress axis near to NS. The focal depth of ML4.1 Xianyou earthquake is determined by waveform fitting method and sPL phase method.
