A tsunami absolutely does not fit our intuition of what waves are. It looks like a wave. But it does not stop. It just continues. That little wave goes on an on, farther and farther inland. After an hour it may still go on. It's a nightmare wave, because it doesn't not fit one's intuition of what waves are.

and it IS a wave. I don't understand the resistance here. It BOTH is a wave and looks like a wave.

But because it does not stop, it is not a "wave". Let's just stop with the strange pedantism.

I'm reacting against the word "intuition" here. Nobody said it isn't a wave. But it's not like a wave as our intuition says.

(Though it does not _always_ look like a wave - check out the timelapse video from Kuji harbor: https://www.youtube.com/watch?v=M1B1J6sgFxk - that's why you'll sometimes see people talking about it looking like a (very) high tide. As an example of the nightmare "wave" which doesn't stop, and is thus un-intuitive.. https://www.youtube.com/watch?v=3618dZoiaPE which is incidentally also from Kuji, but from 2011)

		I know what you’re talking about. But intuitively it’s still a wave.
