As usual, they got a whole bunch of details wrong. To start with, the *south* side of Kauai faces south, not towards Alaska. It does, however, point towards New Zealand. About 155,000 years ago, the northeast corner of New Zealand had what is called the Ruatōria Giant Avalanche, a submarine (underwater) collapse of part of its ocean shelf into a trench. Some of the blocks of rock involved were more than 18 kilometers across and traveled 50km underwater. Definitely able to create a tsunami. While such gigantic collapses are rare, smaller ones happen far more often. Even though its tsunami likely hit some or all of Hawaii, its direction of force would be mostly towards South America.
