Fig. 1From: V S30, slope, H 800 and f 0: performance of various site-condition proxies in reducing ground-motion aleatory variability and predicting nonlinear site responseDistribution of the KiK-net data set considered in this study. The three top plots correspond to the magnitude (M w)–distance (R JB) distribution. For these three plots, the bins with different colours correspond to seven sample-size subsets with increasing PGA values from 0.001 to 1 g. On the three bottom plots, the distribution of PGA versus distance (R JB) is shown. In these plots, the distribution is given by bins of Magnitude, M w = [4–8]. On the left we take all data sets, in the middle plots the show data correspond to V S30 < 300 m/s and in the right plots the data are given for V S30 > 800 m/sBack to article page
