Abstract

Focal mechanism provides key information on seismogenic fault and helps to understand tectonic stress field and . First-motion of direct P wave recorded at regional seismic station and teleseismic body wave were employed to invert focal mechanism of Lushan Ms 7.0 earthquake, April 20, 2013. The strike, dip and rake of fault planes of our results are 208°/41°/98°and 220°/46°/93°respectively. Both fault plane and centroid depth are close to results provided by other institutes with different methods and dataset.

Key words： Lushan Ms 7.0 earthquake; focal mechanism solution; centroid depth
