Earlier quoted context omitted.

Do you mean 22:17:15? Thank you for posting this! The moment of the eruption is really amazing to watch!

Oops, yes, corrected, thanks!

Is there a way to time link to live YT videos? Looks like t= is ignored.

Is there a significant chance this turns into another Eyjafjallajökull situation with huge disruption to global travel, just in time for Christmas?

Only if magma starts erupting in the ocean, then it will make significant amounts of ash. It doesn't appear to be making large amounts of ash now, and I think the general consensus is it will not.

Does the footage look slo-mo to anyone else? Is that really how lava (magma, idk what its called) actually move through the air?

I think it’s a trick of the mind. The “flames” can be 100 meters tall, hence the magma just looks as it moves slowly at a distance.

Is it normal for there to be such a long (4km!) fissure with lava erupting? I always was under the impression a pit formed and then filled with lava which would then overflow out the sides, rather than a long rip in the earth like this.

Yes, this is pretty normal for a basaltic volcano such as this one [0]. This is also what happened on Mauna Loa recently [1].

This is naturally much, much bigger than the eruption in Fagradalsfjall...the fissure is about 2.8 to 6 kilometers long and still growing. https://www-mbl-is.translate.goog/frettir/erlent/2023/12/19/...

If you scrub the live stream you can watch the fissure expand.

Starts at around 22:55 for fifteen or so minutes. Pretty terrifying, but they seem to have it all under control.

It’s difficult to get any sense of scale, but there’s some good panning shots where you see how close the power station is.
