Fig. 7.

Surface height and velocity distribution for a large source (L = 2a = 60 km). The permanent sea-bottom deformation is given by d₀ exp (−x²/a²), where d₀ = 1 m, and the source duration is T = 31 s. The water height at the surface is shown in the upper panel, and the velocity distribution from the sea bottom to the sea surface is shown in the lower panel, for each elapsed time t from the start of sea-bottom deformation, (a) t = 1 s, (b) 10 s, (c) 30 s, (d) 90 s, (e) 400 s, and (f) 600 s. The vectors indicate the direction of the flow velocity in the fluid in the lower panel.
