There is a correlation between anomalous Schumann resonance and seismic activities. Pre-earthquake Schumann resonance anomaly is an important manifestation of LAIC (Lithosphere-Atmosphere-Ionosphere Coupling), which is probably connected with seismic ionospheric disturbance. The system parameters and research results of statistical and seismic case analysis observed in Yunnan Schumann resonance monitor stations are introduced in this paper. The research shows that Schumann resonance monitor is a feasible seismic electromagnetic precursory monitor method.
