The electric field changes induced by seismic events are known as seismoelectric effects. This paper investigates the seismoelectric response in terrain with undulating geological layers induced by apoint source excitation. Through theoretical models and numerical simulations, the propagation characteristics and spatio-temporal distribution of seismoelectric effects induced by point source excitations in undulating geological layers are analyzed. The results show that the amplitude and direction of seismoelectric effects induced by point source excitations are influenced by the terrain and geological layers, while the undulations in the terrain also affect the propagation path and velocity of seismoelectric effects. These findings contribute to adeeper understanding of the interaction mechanisms between seismic and electromagnetic phenomena and provide important insights for earthquake prediction and geological exploration. Keywords: seismoelectric effects, undulating geological layers, point source excitation, propagation characteristics, numerical simulation
