This is just a short piece about mounting unrest along the extension of the Veidivötn Fissure Swarm as it is running through the Torfajökull volcano.
Torfajökull has two known magma reservoirs, one on the south east side that is mainly andesite-basalt, and a rhyolite chamber towards the south-west.
The current lineament is having the rhyolite reservoir at the southern tip. The rhyolite is believed to be gas poor, but an intrusion of fresh basalt from depth might reactivate the magma.
This is obviously very early, and quite likely to end up with a whole lotta nothing happening, but this is Iceland so you never know.
What we think we can see in this early stage is the start of a deep root filling with fresh basalt, combined with shallow tectonic activity as the southern tip of Veidivötn is moving slightly.
That´s all folks. I will let the plots of Andrej Flis and graphics from IMO talk instead.
Updates will be provided if needed and as we go.
This is still very early. The only thing meriting writing about this is the location, it is a risky place that could mean that an eruption would come. But, this is so early that we are still lacking a lot of things before an eruption could occur.
Before an eruption here we will see quite a bit of change on the nearby GPSes surrounding the aseismic area containing Veidivötn, Eldgjá and Lakí fissure swarms, colloquially known as The Dead Zone. And when I say changes I mean quite a bit, several meters.
Also, there would be a lot of seismic activity. Thousands of earthquakes, some ranging into the M5 range. Tearing apart one of the major seams of the planet would be a noisy thing indeed.
Also, we would see major seismic activity at Bardarbunga.
So far we have not seen any of this. Only a minor smattering along the southern tip of Veidivötn as it transects Torfajökull. It is also possible that even if an eruption happened (still small risk), that it would be a lazy slow extrusion of a slow sticky rhyolite flow.
So, no need to run screaming to tip of the Daily Fail.
