A fairly small US fishing vessel is in relative proximity... https://www.marinetraffic.com/en/ais/details/ships/shipid:43...

Talked to the AI which said: MMI 4.5 in the context of an M8.7 quake, for your vessel: Danger level from shaking alone: Very low in open water. Danger from tsunami in the open ocean: Very low (unless extremely close to epicenter). Prime danger: If near shore, from tsunami run-up, NOT the shaking. Actionable advice: Remain in deep water until tsunami warnings have cleared; proceed to port only when officially safe. Monitor official maritime and tsunami alerts closely after any major earthquake.

That's interesting. Mental note, if piloting a vessel in a tsunami, head to deep water.

E.g. the 2011 tsunami may have had a height of 1.2m or so in open ocean, but when concentrated by shallower water and a bay inlet reached 40m.

		Neat video. It seems to capture the middle between "super high coastal wave" and "shallow but long duration wave in deep water". That's what you'd get with coastal waters several tens of meters deep.
