The Aki-Larner method is extended to allow computation of seismic motions in three-dimensional (3-D) irregularly layered subsurface structures. Applying it to the incidences of plane S waves to two types of sedimentary basin models, we find various effects of 3-D structures on seismic motions such as the rapid growth of surface waves, the appearance of surface waves in localized areas, and the strong spatial variations of waveforms which result from the generation of many surface waves at the periphery. As a result of them, seismic motions in 3-D structures cannot be reproduced correctly in amplitude and duration by the simulation using 2-D subsurface structures.
