Yeah that's it, I couldn't remember details about that show. Where was the Alaska thing?
There are two Alaska tsunamis..that interest scientists.. A big one thousands of years ago..and a smaller one that occured in the 50's in a bay..It was over 1700 feet high. That one showed scientists that in waves caused by landslides, the maximum height of the wave is about equal to the height of the landslide..That's why the Canary Island scenario is so scary..
