Time shift due to reverberation for crustal structures of CRUST2.0 as a function of sea depth (left), sediment thickness (center), and crust layer thickness (right). Average of the time shift in the range of ±160 m, ±400 m, and ±1 km of each point for the sea depth, sediment thickness, and crust layer thickness is indicated by a circle, and maximum and minimum values are indicated by a vertical bar. Bandpass-filtered at a central period of 2.7 s (open circle), 3.8 s (blue), 5.3 s (red), 7.5 s (green) in the top panels, 10.6 s (open circle), 15.0 s (blue) 21.2 s (red), and 30.0 s (green) in the bottom panels
