Fig. 8From: Evidence of strong long-period ground motions of engineering importance for Nankai Trough plate boundary earthquakes: comparison of ground motions of two moderate-magnitude earthquakesPlot of radial (left panel), transverse (middle panel), and vertical (right panel) component velocity Fourier amplitude spectra at the AICH15 site (see Fig. 1 for location) for the 2004 (black curve) and 2016 (red curve) events. See Fig. 7 for the bandpass-filtered velocity seismograms and Fig. 6 for the accelerograms at the siteBack to article page
