This article presents the domain reduction method, a two-step finite element methodology for modeling earthquake ground motion in highly heterogeneous localized regions, and its application to hill topography. Four hill models, considering a surface weathered soft layer and layered system under the hill, are excited by a point source and plane waves. The amplification of seismic ground motion on and around 3-dimensional hills are compared to those of 2-dimensional hills and simple 1-dimensional amplification. The complicated pattern of amplification generated by collaboration of hill topography with layers are illustrated and quantified. The peak values and peak frequencies of amplification factor around the top of 3-D hills are larger than those of 2-D hills and 1-D amplification. It suggests that 1-D approximation of subsurface structure under a hill is inadequate when 3-D effect is significant.
