Fig. 8From: Subsurface velocity structure and site amplification characteristics in Mashiki Town, Kumamoto Prefecture, Japan, inferred from microtremor and aftershock recordings of the 2016 Kumamoto earthquakesAcceleration response spectra with 5% of damping ratio derived from recordings of event EQ18 in Mashiki. Yellow, purple, blue and red traces indicate the response spectra at sites S1, S6, S7 and KMMH16. Dashed line shows the geometric mean of the response spectra derived using observed accelerograms at S1–S3 and S5–S8Back to article page
