We investigated the relationship between the characteristics of nonlinear soil response and site conditions at various seismic stations using a large number of strong motion records and a simple index of soil nonlinearity, DNL, which can be derived from seismic record only. We found that stations which show considerable amplification during weak motion tend to show the evidence of nonlinear soil response clearly in terms of DNL, while the stations with smaller soil amplification during weak motion did not show nonlinear soil response clearly even during strong motion. The relationship between soil parameters, averaged shear-wave velocity for soil layers for example, showed poor relationship to the nonlinear soil response characteristics at a station.
