Fig. 1From: 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, JapanSource fault planes of the mainshock by Asano and Iwata (2016) are projected with black rectanglesLocations of epicenters and strong-motion stations in Kumamoto region, Japan used in this study. Red circles denote epicenters of the 2016 Kumamoto earthquake sequence with magnitudes. A star with a black circle denotes an epicenter of the mainshock. Inverse triangles denote strong-motion stations of K-NET, KiK-net, and JR Kyushu, and temporary seismic stations. Temporary seismic stations were installed by Yamanaka et al. (2016) and Tsuno et al. (2017). Back to article page
