Basin-induced Surface Wave
Basin-induced Surface Wave :
Surface waves generated at the edges of a basin or at a tronglateral discontinuity inside the basin by incident body (S or P) waves. Their amplitude and waveform depend on the basin structure along the ray path from the edge (or the discontinuity) to the site. If the site lies in the central part of a large sedimentary basin, the basin-induced surface waves appear much later than the direct and reverberated S waves. The term secondary surface waves sometimes used for them is not appropriate since their amplitudes can be of primary importance
