     Based on the burst theory of seismic structure, the mechanism of impending precursor wave has been revealed. The seismic occlusion body(SOB) is an energy storage structure, when its fluid pressure reaches the sum of breaking strength of rock strata and gravity, the localized rupture of SOB which occurs under the impact of the tidal force and the expansion of cracks will result in the rupture flow and rupture wave; the alternating shock loadings and unloading collapses superposed by the tidal wave will form the resonant wave as the earthquake precursors, and the resonant wave will spread to the surrounding rocks in phase and group velocity; the vibration frequency and period of the tidal wave are the characterizations of the intrinsic frequency and period of the SOB. The wave velocity and period can be acquired by the high precision and antiinterference geoelectric instrument PS100HRT before the outbreak of an earthquake, and thus the epicenter and magnitude can be determined. Based on the resonant wave amplitude increasing with time after the emergence of the wave and the lunitidal rule, earthquakes occurrence time can be determined. The theory of earthquake and impending earthquake and their diagnostic techniques are already mature; China is expected first to achieve the earthquake prediction in the world. By exploring and identifying the seismic occlusion body, we will be able to utilize the seismic energy just like oil and gas someday.
