You see, they're all connected to the same body of water. And if the tsunami was directional towards the Japanese coast it would've caused issues there.

I think we all know that.

I just don't see how this had anything to do with typhoons and surf contests in Japan, seemed silly.

I guess I didn't get the "joke"

Tsunamis from the 1964 Alaska earthquake (M9.2) killed 12 people in California and caused damage in Japan and Hawaii. Tsunamis can travel for a very long distance in open ocean.

Alaska is pretty close to Asia, especially if you look at the great circle distance.

Cargo planes from China, Korea, and Japan normally refuel in Anchorage, and before the extended range of modern passenger jets, most passenger planes also had a refueling stop there.

In 1983, KAL Flight 007, a Boeing 747 passenger airliner en route from New York to Seoul, was shot down by the Soviet Union after departing Anchorage and inadvertently entering Soviet airspace.

Here's the big Japanese tsunami that devastated Fukushima arriving in California.

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.

In Japan, TV advisory was extra rough seas (no tsunami) on pacific side throughout the day tomorrow (Friday) as a result of this earthquake.
