Through analyzing the data of Fujian Shunchang ML4.9, 4.7 earthquake on March 13, 2007, which of seismic sequence analysis, the focal mechanism solution, isoseismal of seismic intensity, seismogeology and seismogenic structure analysis, P-wave velocity structure around the epicentre, we can generally conclude that: Firstly, sequence indicates the characteristic of isolated seismic sequence. Secondly, the seismogenic structure is Zhengfang (f2) fault. Thirdly, Nanping - Ninghua fault zone should be valued as the main seismotectonics of Fujian. Finally, the moderately strong earthquake may occur  in Shunchang – Nanping area  in the  future .
