Tsunamis are only a foot or two in height because they are so long. They only get huge when they hit shallow water and begin to back-up on themselves.

We were a little surprised that the waves were so large. But the reason we were surprised is because this was the first time measurements had been taken of large waves.

It was very fortuitous for our moorings to be installed right in the path of Ivan. From theses measurements we have learned that waves over 90 feet are not rogue waves , but are actually...

They break up and dissipate when they start feeling the bottom. They don’t last that long. They don’t travel that far, but they can bust up everything [in their path].
