Note: not a geologist.
In the last few weeks there have been swarms of earthquakes on the mid-Atlantic ridge near Iceland. These aren't magma on the move, just tectonic strain being relieved as the plates stretch apart.
Now there's one going on under the tip of the Reykjanes peninsula.
I think within 2 weeks, this unzipping will reach where the full magma chamber near Grindavik has been looking for a way to empty itself.
I expect at least a magma intrusion.
