EQ Earthquake swarm north of Svalbard

[tanstaafl]

I'm a little surprised no one has posted about this swarm that is taking place north of Svalbard/northeast of Greenland. As far as I know there's no land where these are taking place, so I suspect an energetic volcanic eruption on the seafloor. There have been quite a few earthquakes in the last few years scattered over the far northern Arctic (including at least one at a known seafloor volcano), so maybe it's just various fault lines letting go and this swarm is just the latest and most active of the lot. (note that the times shown are for the West Coast, not UTC or earthquake local time)

First I've heard of them happening.

Any relation to the swarms in Iceland?

Good question! I don't know but others here may have more answers.

From the screenshot I posted in the OP it's on the same plate boundary as Iceland but these earthquakes appear to be more than 1,000 miles from Iceland (which is southeast of Greenland). By the way, there's now a 4.1 earthquake in northeastern Greenland (2022-05-21, 11:02:44 (UTC-07:00)) that's relatively close to the new swarm, although I can't imagine how it might be connected.
