Fig. 12From: Microtremor array surveys and development of the velocity model in the Hakodate Plain, Hokkaido, JapanComparison of the Fourier amplitude spectra of observed and simulated velocity waveforms. The observed Fourier spectra are plotted with gray lines. The Fourier amplitude spectra of the simulated waveforms with J-SHIS V2 model and our new model are plotted with purple lines and red lines, respectivelyBack to article page
