Amateur footage of a Japanese coast guard boat riding up and over large tsunami waves after the March 2011 Tohoku earthquake. It is short and unedited.

Cited in threads about earthquakes and tsunami warnings as a visceral view of what a tsunami wave looks like at sea.

Same video with normal controls: link Longer & unedited video from cited source: ▶ this video . based on the translation of what folks are saying, this is a 10 meter wave at 38 meter sea depth.

IIRC the water displacement on open seas is super modest, only when the thing hits shallower water near the coast does it become a problem Edit: ▶ this video They're a few miles off the coast, ~10 m high waves, 38 m deep water according to some comment that translates the audio. pretty scary vid, for sure.
