Seismicity of the Longmenshan fault zone and its vicinity before the 12 May 2008 Wenchuan MS8.0 earthquake is studied. Based on the digital data of seismic waveform observed from regional seismic networks and mobile stations, earthquake focal mechanism solutions are determined. The results obtained show that the seismicity of Longmenshan fault zone before the 12 May 2008 Wenchuan MS8.0 earthquake were in a stable state. No obviously intensified seismic activity appeared. According to focal mechanism solutions of some small earthquakes before the Wenchuan earthquake, the direction of principal compressive stress axis was WNW-ESE. The earthquake fault planes had both NE-SW and NW-SE strikes. The strike of the NE-SW planes is among N50°—70°E, their dip angles are 60°—70°, being quite steep. Most earthquakes were characterized by dip-slip reverse faults, and minor were of strike-slip faults. The directions of principal compressive stress axes, the strikes of fault planes and the faulting types of some small earthquakes before the Wenchuan earthquake are in accordance with that of the main shock. The average stress field along the Longmenshan fault zone before the Wenchuan earthquake is also consistent with that obtained from focal mechanism analysis of the main shock. Zipingpu Dam is located 20 km east to the initial rupture area of the Wenchuan earthquake. The increase of small earthquakes in Zipingpu Dam area before the main shock may be attributed to that the reservoir was just in the period of water discharging. Focal depths of the small earthquakes occurred near the initial rupture area of the main shock are in the range of 5 to 14 kilometers, and are identical with that of the Wenchuan earthquake.
