Two‐dimensional finite element modelling of subsurface anomalies at shallow depth has been done to obtain the response to incident SH‐waves. Vertically incident SH and obliquely incident SH have been examined. Power spectral ratios were studied to determine the effect on the surface seismograms of the position, shape, depth, size and material composition of the anomaly. A number of relationships between the surface response and the anomaly has been identified. These relationships may be used in solving the inverse problem: given the seismic motion of the ground surface, determine the physical properties of the underground structure.
