---- fairly big one for the region, although I'm not sure how concerning it is.
No tsunami warnings issued thus far and not located on land

That's a big one.. lucky it was far enough out to sea... as you say I am seeing no tsunami warnings.

I'd hate to be a ship in that area right now.

Me too, but I thought that the big waves would be more where that hopefully virtual ship isn't right now.

We were in a small boat in a small lake in Alaska when a small quake hit. It was a tiny jolt with a tiny noise, but it was a very big reminder of how vulnerable we all are, in pretty much all things.

Fishy

This is a volcanic island, they are prone to earthquakes. The depth is deep. It may not have been felt. The popuilation of that island and the sandwich islands together is 30.

Why?

That's certainly a doozy for down there. Not unheard of, IIR, though. Wonder if anywhere on other plates is going to react? Should be interesting to see where another crops up, if at all. Though I'm wondering if this might be a reaction to the biggie in the... where was it, Tonga? Fiji? Not too far back & near one of them. Maybe this one is a plate re-situating itself kind in response of thing.

I don't think you quite understand how a tsunami works in this case. A couple hundred feet of water depth or deeper & boats are fine. It's the shallow areas where the water has nowhere to go but up the shelf & onto land that is the risky place to be.

Yes , it's near other plate boundaries. Couldn't get my pic to upload for illustration. I did wonder if it can set off another plate to move.

PS I need to fix my op link , I see it's a 404
