Earthquake Tsunami Waves
Discussions focus on waves generated by an earthquake, debating distinctions between tsunamis, rogue waves, regular ocean waves, their physics, heights, and potential dangers like harbor evacuations.

Cool! Some info on tidal waves for water hits would be even cooler
No, waves are anticipated, tsunamis a possibility.
Ocean waves crashing against a retaining wall. It doesn't matter how many small waves come, it's only waves greater than a certain height that are dangerous.
Reading the news article, it says that the waves are about 1m in height, some are about 60cm in height. How do they distinguish that these waves are caused by the earthquake and not waves created by other causes (ocean currents, wind etc)?
water is very dampening. tsunamis are from sustained force
Sure it's a wave, but tides, swells and waves all oscillate just on different frequencies and amplitudes. When they all align you get rogue waves and to the casual observer of a tsunami, a wall of water coming your way.
You mean like a 250m high wave?https://en.wikipedia.org/wiki/Vajont_Dam#Landslide_and_wave
Maybe you get rogue waves in it too
There are pressure waves in the ocean too.
IIRC the water displacement on open seas is super modest, only when the thing hits shallower water near the coast does it become a problemEdit: https://m.youtube.com/watch?v=-VcWF8dIDj4They'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.
