Fig. 5From: Frequency-dependent amplification of the Sanriku tsunamis in Ryori BayFourier amplitudes of the water surface elevation changes of the 2011, 1933, and 1896 tsunamis at site A specified in Fig. 1b (black, blue, and red), corresponding to the waveforms of Fig. 4a. The length and time resolutions of the waveforms are 1 h and 15 s, respectively, and the data length for the Fourier analysis is 28Back to article page
