In the paper,some analyses about the failure of rocks are made.It is suggested that earthquakes are actually the instability of nonlinear system,and that load-unload response ratio (LU RR) reflects the closeness of rocks to the peak of stress and marks the danger level of some earthquake prone areas.It is found that the difficulty of impending earthquake prediction happens after the peak of stress.The possibility of impending earthquake prediction is also discussed.
