Average maximum amplitude of the stacked waveforms for each frequency band. The average was taken for each of the analyzed frequency bands, except for the case that noise was dominant. Blue inverted triangles, red diamonds, and yellow squares represent the results of this study, the BSE model (Ide 2019), and the omega-square model (Aki 1967), respectively. Green pentagons and hexagons represent data from Cascadia (Bostock et al. 2015), as presented by Ide (2019)
