How fast is that moving? From the timer on the bottom of the screen it looks like it was only minutes from Alaska to the Atlantic!

This animation is significantly sped up. The red text is showing the time in hr:min:sec, so the waves took about 35 minutes to cross the U.S.

I got there in the end. First I was trying to slow down the timer in my head then I just watched the beginning time and the end to figure it out. Still - pretty damn fast!
