And the fissure is opening up now rapidly.
We currently have a fissure open from 20 to 2.5km, that would make magma rise straight up from the mantle to the top. Probably intense decompression melt driving what we are seeing now. It looks like the eruption will occur 13km due east of Kistufell. This means that this is not a normal fissure eruption that will take the magma out of the central volcano, instead the main bulk would come up directly from the mantle.
The fissure seems to be narrow enough in extension to follow in line with Irpsits idea above.
I expect that the first part will be explosive since it would contain evolved Bárdarbunga magma, but that it in a few hours would go down into a far less explosive stage as pristine mantle derived magma comes into play.
Also, the Glacier is not particularly thick there so expect it to pop up rather fast.
Caveat, I do not yet know 100 percent that it will blow at this stage.*
