Strongly depends on if it's a deep water portion or if it's shallow. In deep water, a tsunami is boring and nearly unnoticable. There's some motion, but it's essentially all low displacement coherent movement and very little other motion. When that mass of water gets to shallow water, it's essentially the opposite, there's effectively big mass of water that's pushed on land, and that's very turbulent.
