This invention discloses an alternating electromagnetic field seismic monitoring network, comprising receiving electromagnetic field signals from high-power artificial and natural sources, and an alternating electromagnetic observation network composed of multiple receiving stations. The network receives electromagnetic field signals from artificial and natural sources through multiple observation stations deployed based on seismic distribution trends, and processes the observation data, including spectral analysis of the observed electromagnetic field time series to obtain the spectrum and self-power spectrum of each electromagnetic field component, as well as the cross-power spectrum between different components. This allows for the calculation of impedance reflecting underground electrical properties, as well as parameters such as apparent resistivity and impedance phase.
