This paper discusses the topographic effects on magnetotelluric response. The authors hcre calculated several magnetotelluric response curves on different topography with finite e ement method, using quadratic triangular element. In the case of Ex-polarization, the effects occur only on the frequency band in which the length of wave propagated under ground is comparable with the amplitude of undulation of topography. In the case of Hx-polarization, the topographic effects are severer than that in Ex-polarization, and it becomes stable as the period increases. The effects are severer on convex place than on concave place. More
