Ever since I was a kid I’ve been fascinated with natural disasters. This is the one of the most fascinating ones. Can you imagine a giant wall of water this size coming at you?

Maybe OT, but to demonstrate a similar thing I once experienced: Been bicycling in the forest like ever so often, and something was off. Stopped. Thought someone suddenly built a large, long wall or building there within a few days, because it wasn't there before. Went about 100 to 150 meters into the forest to investigate what it was. A massive wall of whitegrey smoke, with many nests of flames between 50cm and one meter high. Didn't recognize it as such until I saw the flames shining through. Really thought of it as a wall until then.
