Tonga eruption....

I have had people call me a liar over this but its absolutely true. Was living on a houseboat on Lake Union in Seattle when the Ak quake hit and we were first on the long dock that just was built on piling.
The lake level actually rose and fell just a bit, not much, and also our dock started to "snake" back and forth, all the houseboats were moving around etc.
Long ways from Anchorage but it did have an impact.
Strange stuff...

My father was on the Bremerton ferry during the Alaska quake. He said it felt like the ferry hit something very hard. It came to a stop so they could check for damage. Then they got the news about the quake.

That's interesting, I was on USCG cutters in the PNW Inland passage during tsunami alerts and the only things we felt were like going over a small wave. Like a speed bump.

As they get into shallow water, the wave(s) slows and builds.

Not quite sure between the alert and obvious or not so obvious wave a ferry would think it hit something. Maybe they actually did if they were in a bay just before it hit and the water level dropped dramatically.
