The seismic response of some three-dimensionally irregular topographic feature is calculated successfully by the new formulation of the Discrete Wavenumber-Boundary Integral Equation Method, using the Green's function for a homogeneous half-space given by the Sommerfeld integral. Based on the consideration on the orthogonality of the horizontal wave function, the integral over wavenumber to obtain such Green's function can be truncated at a finite wavenumber. The calculation for some simple problems of surface irregularity, gives stable and reasonable wave forms. It is expected that this strategy can be applied not only to the problems of surface irregularity but also to those of irregular interfaces with arbitrary shape. ƒL[ƒ[ƒhi‰pjF - ‹LŽ–‹æ•ªF - ‹æ•ª @@@ˆÏˆõ‰ï˜_•¶W
