In this paper, the authors focused on global earthquakes with MW≥7.0 and hypocenter depths less than or equal to 70 km from the Harvard Centroid Moment Tensor (CMT) catalog during the period from 1976 to 2009. Based on this, the authors discussed the relationship between the direction of tidal shear stress on the real fault plane and slip direction. At the same time, the phases of tidal normal stress and Coulomb failure stresses on the fault plane in the origin time are calculated. The results show that there are obvious triggering effects when the direction of tidal shear stress is the same with the slip direction, while earthquakes rarely occur when tidal shear stress goes in the opposite directions, and reverse fault earthquakes have the closest relationship with tide.
