Fig. 11From: Application of the on-site P-wave earthquake early warning method based on site-specific ratios of S-waves to P-waves to the 2016 Kumamoto earthquake sequence, JapanResidual standard deviations between the observations and the predictions for PGAs of S-waves against time-window lengths from P-waves arrival at the strong-motion stations. In the figure, standard deviation σ in logarithm is indicatedBack to article page
