Today (08-June-2017) there have been deep earthquakes in Trölladyngja (volcano). This earthquake swarm was shallower than last earthquake swarm that took place in Trölladyngja. Several months ago the earthquakes in Trölladyngja where happening at 28 km depth, but now they are at the depth range of 18,6 – 23,3 km, this means that the magma under Trölladyngja is migrating upwards at fast phase, a lot faster then I thought was possible. Earthquake swarm in November-2015 where slight off to the side, those earthquakes had the depth of 15 – 18 km as I wrote about here. Since November-2015 here has been other activity in Trölladyngja, but that has been in the form of one or two earthquakes so I have not written about it (I never bother with just one or two earthquakes at location due to the amount that happens daily in Iceland).
Last eruption in Trölladyngja was according to GVP (under Bárðarbunga volcano history) was 7000 years ago. Since then nothing has happened. There has been a lot more eruption in Dyngjuháls area and that area is also having deep earthquakes. That area is also covered with ~200 meters of glacier. It remains to be seen what happens next in the Bárðarbunga volcano saga.
Please remember to support my work. As it currently stands I’m completely broke and that’s no good at the start of the month. Thanks for the support. 🙂
