  • This paper focuses on numerical simulation of the seismic electro-magnetic anomaly generation process in isotropic layered medium by means of propagation-matrix method. For the layered model, some are fluid-saturated porous medium, and the others are linear elastic medium. During the simulation, the solid field is taken as a principal field and calculated individually, and its deformation is taken as the equivalent fluid source. The simulation results show that when the seismic wave goes through the boundary of the fluid-saturated porous medium, the electromagnetic (EM) wave is generated simultaneously, which can be used to illustrate the seismic EM anomaly accompanied by seismic source or the seismic wave. On the other hand, it can elucidate EM signal coupled with the foreshock or the tremor.
