I only know this because I clicked on some more stuff after looking at that but the Fukushima tsunami caused a fair amount of damage in the Santa Cruz, CA harbor both to docks and boats. Apparently the waves can get magnified when they go into a narrow channel or harbor. Another thing I only learned today reading the comments of that video is that tsunami literally means harbor wave in Japanese.
