Fig. 8From: 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, JapanPredicted Fourier amplitude spectra of S-waves for the earthquake of Mj 5.8 on April 18, 2016 at the strong-motion stations. Different time-window lengths of 0.64, 1.28, and 2.56 s of P-waves observed in real-time were used. a Strong-motion stations of K-NET, KiK-net, and JR Kyushu. b Temporary seismic stationsBack to article page
