First worry is always a tsunami, but in this case it seems like it only generated a max of ~20cm: https://www.tsunami.gov/events/PAAQ/2021/07/29/qwzteb/7/WEAK...

However, I wonder if this quake so up north would accelerate the breaking of icebergs.

There is old joke that if you use metric when announcing a 50mm tsunami, half of Americans will run for the hills. "~20cm" could mean half a foot or 20 hundred meters depending on how much you remember from highschool. Many agencies have policies on how and where metric should be used in public announcements.

We got an alert in Jefferson county letting us know specifically that there was no Tsunami.

Could have made the olympic surfing competitions interesting (which they moved sooner because of the storm that passed by)

The Tsunami was in Alaska, not Japan.
