This is a short overview of activity in week 44 in Iceland.
Tjörnes Fracture Zone (TFZ)
Earthquake swarm took place in TFZ in week 44. Largest earthquake had the magnitude of 3,5 and other earthquakes had the magnitude of 3,1. Other earthquakes where smaller in magnitude.

A second smaller earthquake swarm took place south of Grímsey. It is not connected to the stronger earthquake swarm east of Grímsey island.
Bárðarbunga volcano
A magnitude 3,0 earthquake took place in Bárðarbunga volcano. This suggests increased pressure inside Bárðarbunga volcano. I forgot to save image of last week activity in Bárðarbunga volcano.
Tungnafellsjökull volcano
Earthquake activity continues in Tungnafellsjökull volcano. As before all of the earthquakes taking place are small in magnitude. At the moment the earthquake swarm activity appears to be centered around the top of the volcano, one of the main craters. Earthquake activity is steady in Tungafellsjökull volcano at the moment. It sometimes drop down, as is to be expected when magma moves inside volcano.

Skaftárkatlar cauldrons in Vatnajökull glacier
Recent survey of Skaftárkatlar cauldrons in Vatnajökull glacier has shown that the eastern cauldron has grown considerable in size. This is now thought to be the main reason why the glacier flood from eastern skaftárkatlar cauldron was the largest in recorded history. The cauldron is now 2,5 sq/km in size and 150 meters deep. Video of the overflight can be found here (Facebook). Measurements and other details can be found here at University of Iceland Earth science website (Icelandic). This are early results from recent survey.
Other things
Please remember to support my work with donations or by using Amazon. Due to problems with the Danish tax authorities I did not get my social welfare paid out this month in Iceland. Reason being that I have not got my copy of the tax statement for the year 2014, that I have . I hope this is resolved in November as has been promised to me. This however means that I have to use the salary for last months work to survive this month, money that I was saving in order to pay for moving cost when I move back to Denmark. If this is not resolved by December, I have to go on emergency income from my municipality. I won’t move to Denmark until this issue with the Danish tax is resolved. The temporary work that I was in is over so I’m going to be updating now when things happen in Iceland or close to it.
Once I’m back in Denmark I can start uploading detailed images of earthquakes and keep a real time watch about what is going on in Iceland. Its difficult for me to do that at the moment.
