a DNL versus V S30, b DNL versus A max, c ADNL versus A max, and d PNL versus A max. The data were separated into three groups based on different PGA levels: PGA < 200 cm/s2, 200 < PGA < 400 cm/s2, and PGA > 400 cm/s2. The relationships between DNL and A max, ADNL and A max, and PNL and A max for each group of data are presented based on linear fitting on a logarithmic scale. The correlation coefficient R is also given for each regression
