| Abstract: | In 2007, total 43 M_L>3.0 earthquake were recorded in Gansu province. Among them 17 events are selected for focal mechanism inversion, using the method of seismic moment tensor inversion with P wave onset. The basic parameters of best double-couple are gotten. Based on the result, the earthquake tectonic backgrounds and mechanism in some areas of Gansu province are discussed. The result could afford reference to earthquake prediction in the region. |
