https://tidesandcurrents.noaa.gov/tsunami/plot.html?stnid=94... So far so good.

Could you clarify what you mean by "good" here? I see a sine wave when I click now, with an amplitude of about .75 meters.

This sine wave is expected:

Since the danger seems to be receding -- I hope NWS & related agencies can use this as a good drill to fix their web properties.

Tsunami.gov couldn't handle the load, and many other official links (like mobile.weather.gov) just dump you into a government shutdown notice. Cell.weather.gov isn't even resolving.

I'm sure someone thought the critical products would still be easily available even with a government shutdown, it sure didn't work out that way.

Wow 15 hours to australia, that thing is moving fast.

Will this wave affect boats? Imagine being on a yacht in the middle of the Pacific (not Atlantic Doh!) when a 10m wave moving at 20m/s hits (figures not accurate just guesses)

Yeah, no more than a bit of swell does though. Best example I can find is this -> https://youtu.be/ZS6EmSxncz4?t=78

Most of the labor contracts (not to mention ADA litigation) for the government require a certain level of service if the property is in use. With the government shut down that's not the case. It's the same reason for the infamous "this website is only available from ~9am to ~5pm" nonsense you can find on certain Social Security/IRS pages.

https://twitter.com/SF_emergency/status/955764708442714113 San Francisco Department of Emergency Management has tweeted that people within three blocks of the coast or five blocks of the San Francisco Bay should be prepared to evacuate. Tsunami Watch for #SF. If you are w/in SF & 3 blocks of the Pacific Coast or w/in 5 blocks of SF Bay, PREPARE TO EVACUATE SO YOU ARE READY IF EVACUATION IS NEEDED. Check on neighbors…

I'm a recent newcomer to the Bay area. What is the Tsunami situation for places like Mountain View? Places like the GooglePlex are pretty close to the Bay. Is there even any real high ground in the area?? If something happens for real, do sirens sound?

Why would a website go down during a government shutdown? It actually takes more work to turn it off, doesn't it?

We like to laugh about the Tuesday siren tests, but times like this are why we do them. If a tsunami really does hit WA and OR expect the waterfront sirens to make a pre-dawn announcement.

Except that was not a test

Is Twitter really the official way to notify people of danger? Or is there also a cell phone warning system?

Earlier quoted context omitted.

There probably won't be 10m waves in the middle of the ocean. The waves will only be a few inches tall, but moving FAST. Then they get dramatically taller as they are forced to slow down in shallow water.

This is the North Pacific in Winter. I'd be surprised if there weren't 10m waves out there.

Well, those waves have nothing to do with the earthquake anyway, and they aren't traveling at the speed of a jet plane :)
