The author has put forward the hypothesis that the driving force of platesmovement is given by tidal force and gravity co-operatlon. In this paper,the hypothe-sis principle is also applied to research seismic mechanism. The authors mainly study the reason whv most of the continental earthquarke oc-curied within 20°-50°S,and explain the reason why seismic time of shallow-focusearthquake is associated with earth tidal.Both of the reasons would be regard as the re-sult of tidal attraction and gravity co-operation,The authers try to prove that tidalforce-gravity co-operation detonates or breeds earthquake.
