West Coast tsunami watch.

I was on an Alaskan cruise a couple of weeks ago when the 7.6 magnitude earthquake hit. The captain getting on the intercom to tell us that we were on tsunami watch was about the most helpless feeling in my life. No internet, no news, no goodbye phone calls, no way out. Made me reassess some things in life.
 
Typical. TWC blew off and slept through the Hill Country floods near Kerrville, TX.
Cable television networks have been in a steady decline for a long time, but post-covid most of them have just turned into complete shit. Channel after channel it's just reality-show crap that gets more and more crass and vulgar and exploitative every year, fewer and fewer scripted series, and just the most shallow and superficial stuff possible. And that's true whether it's traditional networks, "news" networks, and former specialty networks - educational, sci-fi, history, movies, you name it. Streaming is really about the only way to go now.

Watching Fox Weather for updates and there’s papa bear Bill O’Reilly informing me that insomnia is “escalating into a nationwide health crisis.”

Were you in deep water? If so you may not even notice it.

Unlike normal waves tsunamis are a high pressure wave that runs the depth of the ocean. In deep waters this is often unnoticeable. When you get near shore, that volume of water caused by the high pressure that exists miles under water has nowhere to go but up.

Edit: I think describing it as a high pressure wave is incorrect.

The meteorologist on Fox Weather Channel just asked the guest tsunami expert if a watch or warning indicates the greater threat.

Watching the same channel…woman meteorologist just advised people on Maui to head towards Haleakala…that they would probably be safe if they could get a mile above sea level. Absolutely ridiculous. She’s also been absolutely butchering the names of Hawaiian cities and towns…I mean I understand to some degree but someone needs to be in her ear giving g her the correct pronunciations.
 
In the classic movie the Poseidon Adventure the ship was hit by a Tidal Wave.
It appeared that they were in deep waters since it took so long for help to get there.
Movie likely was not realistic.........but a great movie though.
I have wondered if a big ship with a large underwater surface area that is hit broadside by such a pressure gradient could be in trouble.

I think smaller ships are probably safer in a tsunami. I don’t know that for sure but I am sure someone here has more fluid dynamics knowledge than I do.

My mother and her parents were on an ocean liner that had departed Yokohama shortly before a tsunami from the 1923 7.9 Earthquake that killed 140,000 people hit Yokohama and Tokyo. My grandmother told me that because the liner was in deep water, the people on the ship didn't know they had passed over a tsunami. She said they only learned of it when the ship's captain told them about it, which he had learned from radio traffic. And she didn't learn how terrible it was until they arrived in Vancouver. That really surprised me as a young boy, but when I later learned in school about how tsunamis actually worked, I was already primed to believe it.
 
Just arrived in Atl after leaving Oahu yesterday afternoon. Gave car keys and townhouse keys to visiting stepdaughter and her boyfriend about 30 mins after the warning. His first time there and this happens.
