Comparison of weak-motion (PGA < 20 cm/s2) mean spectral ratios with strong-motion spectral ratios from four individual events recorded with PGA > 100 cm/s2 at the a KNG201 and b KNG203 sites. The black lines denote the weak-motion mean spectral ratios. The gray lines denote the range of one standard deviation. The red lines denote the strong-motion spectral ratios for individual events. The magnitude, focal depth, epicentral distance, PGA, and DNL for each strong-motion event are provided inside each frame
