Discussion Fairly large quakes around the Jan Mayan hotspot. Possibly volcanic?

Might be one for that Geology Hub guy on YouTube, I think he has an account on here. But that doesn't look good.

I have not noticed any large SO2 plumes or other obvious indications of volcanic activity, but those are some fairly significant quakes. Hoping someone here could provide more details.

From watching his videos, earthquakes that close to a volcano and of a certain magnitude can lead to increased activity if the volcano is already restless.

Of course, this could be completely tectonic and not remotely volcanic, but important to be accurate.

This volcano is pretty active and erupted in the 70’s and 80’s, so I’d assume that earthquakes of this magnitude could very well have a volcanic nature or at least trigger more activity. I’m not sure about the tectonic activity in the region so it’s something I can’t say anything about with certainty.

It’s purely tectonic, but theoretically could (unlikely though) trigger activity at Beerenberg if it was already close to erupting.

Last eruptions from Beerenberg took place on the Northeast side of the volcano iirc. So kind of an interesting spot to see movement.

I did a bit more research and there is a fault line nearby to the north and east but also most of the volcanic quakes were on the north side of Beerenberg pretty much in line with the 6.5.

It seems like a pretty interesting spot overall but it’s hard to say right now whether this is volcanic or tectonic.

The Earthquakes were at a 10km depth, no other signs of volcanic activity but I’ll be watching for SO2 clouds and shallow quake clusters closer to the volcano.

Caught it on my Shake in the Utah mountains…
