I remember in 2015 watching this great tsunami video at a harbor. It was about 11 minutes long.
At the start, there's just a white line at the horizon. Then the fishing boats in the harbor start rocking and jangling. Then water starts pouring over some walkways and sea walls.
Eventually the cameraman backs away and starts climbing a concrete tower; water starts to flood over the area where they had been standing. I think they climb a couple stories and are safe up there.
I haven't been able to find the video in years, but I remember being fascinated by it and I'd love to watch it again.
Edit: I never expected to find that video again, but here it is. A little more terrifying than I remember.
It never got above the boats, cant be more than a few feet tall
The port's wall slow down the entry of the water and the boats can float. The "tide" caused by the tsunami was several meters.
I feel like you're making a bad joke. Did you drop your /s?
