This is a short update on Bárðarbunga volcano activity.
Earthquake activity continues in Bárðarbunga volcano and shows no signs of slowing down. Two swarms have appeared in Bárðarbunga volcano system. One is at location called Kistufell, while the second one is at the south-east part of the Bárðarbunga volcano. Increase in earthquake activity in south-east part of Bárðarbunga volcano seems to increase harmonic tremor. I am not sure why that is. As of now (when this is written) no eruption has been confirmed in Bárðarbunga volcano, the volcano is under glacier so confirmation is difficult at best.

Harmonic tremor remains high on the Dyngjuháls SIL station. Why that is not clear at the moment. Copyright of this image belongs to Icelandic Met Office.

So far no major eruption has started in Bárðarbunga volcano. That might change without warning as this activity continues. There is a risk of large earthquakes taking place before such eruption. Since the crust in this part of Iceland is thick (up to 40 km thick) and last eruption in Bárðarbunga volcano took place in the year 1794. The eruption in the year 1910 took place in a volcano named Hamarinn and is south-west of Bárðarbunga volcano. Fissure eruptions are also a feature that Bárðarbunga volcano has, if this activity is going to result in such eruption is something that is impossible to know at current time.
Current status changes fast. I post new information on this activity as needed and as things get more clearer on what is happening.
Excellent summary. Thank you for the updates.
An M3.9 about 25 minutes ago. Largest so far.
Dear Jón, is there anything known on how big the 1794 andere 1910 eruptions were? Ejection of lava (how much), quantity of ash? Thanks for your answer!
Kind regards, Henk Weijerstrass
The eruption in 1910 took place in a different volcano (called Hamarinn). Size of the eruption in the year 1794 is not known or how long it lasted. This is according to Global Volcanism Program information (link in top of this article).
Things certainly looking interesting at Bardarbunga, we in the UK are in an Icelandic (ish) air flow at the moment.
I imagine UK airspace are crossing fingers that only something minor happends!
According to http://vmkerfi.vedur.is/vatn/index.html
halfway 15 august water level in Svarta has suddenly risen, carrying a sudden 10% more water. That is a bit downstream, meaning the reason (the source is upstream…) lies somewhere earlier in time.
Weird to see that the possible cause of this: heat in Bardarbunga, started a day later than I would have expected from these graphs.
(Open up that link, login with the details given on the right, and go to Norðurland: Svartá; Bárðardal; V324)
I don’t know where exactly this station is located, but Svartá is not a glacial river, the water comes from Ódáðahraun. One possible path for meltwater from Bárðarbunga would be Skjálfandafljót. But according to the location of the earthquakes, meltwater could be expected more likely in Jökulsá á Fjöllum, which is quiet right now.
In 2002 a chart was posted online of positions of an incoming planet. Having always liked to use a small telescope to see the planets I decided to look. The object was spot on the various charted positions over the time I watched. The large planet entered the inner solar system and carries with it much gravel and debris which surrounds it. Many in our back yard viewing group made official form reports but remarkably none received a reply from anyone including NASA. The source of the chart that was indeed correct made the comment that every volcano active within the last ten thousand years would go off now as the result of this long term orbit planet’s crossing.
Can you please keep this nonsense to your self. As science will tell you, no planet has entered the inner or outer solar system. Such object would have been spotted all over the world and it would have created an gravity chaos on the plants already in the inner solar system.
Planet on long orbits also have more distance between them self and the star they orbit. It is the nature of how things work in the universe. Distance also limits the effects on gravity on such objects, along with radius and mass of a object.
Forgot to mention that also conductivityy raised at the same moment, from 100 to 130 micro Siemens.
Can you tell me where exactly is Svartá, I cannot find it on google. Thanks SJ

a simply thought.Why dont scientists go there with a helicopter to see the situation of the glacier .If there is such activity the glacier will have cracks from the underneath heat
Low clouds?
they were in my mind ahahahhha they did it 🙂
