Wow 15 hours to australia, that thing is moving fast.
- raverbashing 9y agoSlower than the speed of sound in water, but still very impressive
- jedberg 9y agoFaster than an airplane though.
- yitchelle 9y agoPerhaps, the arc distance traveled for the wave is a smaller than the plane's. The plane is flying 10Km in the sky.
- joe-aws 9y agoThe difference in arc lengths is less than you'd think-- It's only about 20km further assuming Alaska is 1/3 of the world's circumference away from Australia. (1/3)*(2*pi*(r+10) - 2*pi*r) = (1/3)(20*pi) ~= 20
- yitchelle 9y agoWow, that is surprising. I should have thought about it further. The radius of earth is 6371Km and 10Km works out to be 0.15% of it. So 20Km is reasonable.
- Jedi72 9y agoWill this wave affect boats? Imagine being on a yacht in the middle of the Pacific (not Atlantic Doh!) when a 10m wave moving at 20m/s hits (figures not accurate just guesses)
- pimmen 9y agoIt will absolutely affect boats in the Pacific.

- kijin 9y agoThere probably won't be 10m waves in the middle of the ocean. The waves will only be a few inches tall, but moving FAST. Then they get dramatically taller as they are forced to slow down in shallow water.
- jraut 9y agoThe disturbation will be less than 1 meter at open. The actual wave gains altitude only when it hits the shallow waters.
- wiredfool 9y agoPicture a 1m high wave with a crest to crest wavelength of 100km. That is pretty much what an open water tsunami looks like. This is why when there's a tsunami warning, boats are supposed to leave the harbor, where it's dangerous, and get to sea where they won't notice the wave.
- poooogles 9y agoYeah, no more than a bit of swell does though. Best example I can find is this -> https://youtu.be/ZS6EmSxncz4?t=78 https://youtu.be/ZS6EmSxncz4?t=78
