Spatial variations of simulated coda amplitudes for Event 1. Coda amplitudes were evaluated by calculating the average of amplitudes at lapse times of 70 s–90 s. The upper panels are the map view plots of horizontal coda amplitudes for frequency ranges 1.o–2 Hz and 2.0–4.0 Hz. The blue contour lines are the thickness of the JIVSM sedimentary layer. The bottom panels show the horizontal coda amplitudes as a function of sediment thickness. The colors in circles of the bottom panels represent the bathymetric depths
