On 25-April-2018 and on 26-April-2018 small earthquake swarm took place in Katla volcano. The earthquake activity took place in the south part of the Katla volcano caldera.

Largest earthquake in this swarm had a magnitude of 2,1 and 1,8. All other earthquakes where smaller in magnitude. This also suggests that summer earthquake activity in Katla volcano is starting and more earthquake swarms like this can be expected in next few months.
Please remember to support my work. It helps me to keep everything working. Thanks for the support. 🙂
This article contains information about two volcanoes. There is currently also a lot of earthquake activity in Bárðarbunga volcano. But that is going to be a different article if needed.
At the moment there is a continuous minor earthquake activity happening in Öræfajökull volcano. Largest earthquake in current swarm had the magnitude of 2,0 and second largest earthquake had a magnitude of 1,5.

What worries me about Öræfajökull volcano is that it already seems to be at stage two in its path to an eruption. Article explaining that can be read here, Seismic patterns help forecast eruptions from quiet stratovolcanoes
There has been minor earthquake activity in Tungnafellsjökull volcano in recent days but mostly in last few hours. It remains unclear at the moment why this earthquake activity is happening. It is a possibility that this just tectonic stress due to Bárðarbunga volcano activity in 2014 – 2015 eruption.

As it currently stands I don’t think anything is going to happen in Tungnafellsjökull volcano for now.
Please remember to support my work. As it currently stands I am going to be super broke in May. But that is also going to be the last month that is going to be the case (I hope). Thanks for the support. 🙂
This morning (on 20-April-2018) an earthquake swarm took place in Torfajökull volcano. This was a minor earthquake swarm and largest magnitude was 2,4. All other earthquakes where smaller in magnitude.

There isn’t a lot happening in Katla volcano on this image. It is all quiet at the moment. In general it is also really quiet in Iceland at this moment.
Please remember to support my work even if it is quiet at the moment in Iceland. It is impossible to know when that changes. I also have the bill problem for May ongoing and that is explained here. Thanks for the support. 🙂
During the night of 9-April-2018 a swarm of earthquake appeared in Öræfajökull volcano. This activity has quieted down again for now. Largest earthquake in this swarm had a magnitude of 1,5 but all other earthquakes appear to be smaller than 1,0 in magnitude. Depth seems to have been at 6 – 8 km, but depth information doesn’t seems to be fully accurate. I don’t know why that is. Total number of earthquakes was 22 in this swarm.

I am not sure why this earthquake swarm activity pattern happens and then vanishes. I do find it troubling that it does this and I think this is happening more frequently now than before. Earthquake magnitudes continue to be small but that might not be the whole story of what is currently happening in Öræfajökull volcano. There is no major change in conductivity in the glacier rivers from Öræfajökull volcano.
Please remember to support my work with donations. I spend a lot of time gathering information for articles that I write, even short articles about earthquake activity. I ask for donations in a special article now because the situation in terms of money for me is considerably worse than I had hoped for April. I am also trying to save up for the bills I have to pay in May. Since in Denmark many bills are only sent every 3rd month* and that has resulted in a minor issue for me as the amounts get really high. I’ve never been able to get ahead of that issue even if I tried to do so. It also complicates this issue is the extra tax I have to pay while I am living in Denmark. Since I need to pay this extra tax it means that I lack the money for saving up for the three months bills or at best can only save little money and use as little as I can to buy food. Since I’ve been doing that for several months now and it doesn’t get any easier. This problem is going to end when I move from Denmark by the end of May-2018. When I move to Iceland I don’t have to pay the extra tax in Denmark.
I am moving to Iceland from Denmark for a short time. The long term plan now is to move to Spain** after living some time in Iceland. Moving to Spain requires more work than I have current done so I’ll be living in Iceland during that time. I just I can find somewhere to live during that time, the housing crises in Iceland is awful at the moment and I don’t think it is going to improve in next few months. The reason for moving to Spain is the cost of living in Iceland and the housing crises. I can’t afford buying a apartment in Iceland because the price is high and getting higher. Getting something rented is also a big problem in this situation. What I am going to do in Iceland is simple, pay down all the debt I currently have and save up for a payment in a condo in Valencia, Valencia, Spain. I am going to be remote running my geophone network from Spain. It is going to be considerable easier once I start upgrading to Raspberry Shake sensors from my current hardware (that hardware is getting old and needs replacing).
I do more background work in connection with this website than many people realise. Sometimes I am looking at data or maps and sometimes I am trying to organise the earthquake collection I now have. I got a backlog to 2014 that I need to short out when I have the time (to weeks rather than months). Over the last 4 years I’ve recorded well over 7000 earthquakes due to heavy activity in Iceland.
The fault valley created by the rifting activity in 1875 that triggered a eruption in Askja volcano and Bárðarbunga volcano (Tröllagígar, south-west part of Bárðarbunga volcano system). The new rift cycle has started and now it started with an eruption in Bárðarbunga volcano. The rift valley on the map is going to get bigger in the future, but it is impossible to know when that might happen.
* This means the amounts I have to pay each time is higher than if it was a monthly payment. I prefer to have all bills monthly but that is not an option in Denmark for the internet bill and electricity bill. There is one bill that is every six months and I paid that one in March. This has been a big problem for me for a long time now.
** There no extra tax for me in Spain. Instead I pay all the tax in Spain from my welfare income in Iceland in accordance with Iceland – Spain tax treaty. The tax I have to pay in Spain is also lower than in Iceland as I understand it. But I have many things to figure out before I can move to Spain for good and a lot of money to save up before that happens.
Thanks for all the support. 🙂
This is a short update on the activity in Öræfajökull volcano.
Over the past month the earthquake activity in Öræfajökull volcano has been mostly stable and majority of the earthquakes happening are small in magnitude and most in the range of 0,0 – 1,0. One magnitude 2,8 and magnitude 3,0 earthquake have happened in this time period (article here).

This earthquake activity is easily masked by strong winds and bad weather in the area. As summer approaches in Iceland risk of such storms is now smaller than during high winter. It is only when larger earthquakes start to appear that the risk of an eruption becomes serious. Until then this is just earthquake activity in Öræfajökull volcano that needs to be monitored.
Yesterday (05-April-2018) two earthquakes happened east of Grímsey island. The first earthquake had a magnitude of 3,0 (18:12 UTC) and the second earthquake had a magnitude of 3,3 (18:14 UTC). There is a good chance both earthquakes where felt in Grímsey island even if it was not reported.

Few smaller earthquakes followed the main earthquake events but since then everything has been quiet in this area.
Please remember to support my work with donations. I am currently trying to save up for May bills (since in Denmark some bills come in 3 month cycle) so I can pay them without any issues. Along with just trying to survive. This is the last time I have to deal with this type of issue since I move back to Iceland in end of May. Thanks for the support. 🙂
Yesterday (31-March-2018) at 09:35 UTC a magnitude 3,2 earthquake happened 43 km west of Grímsey island. Due to distance from land this earthquake was not felt far as I know. Second largest earthquake had a magnitude of 2,6. All other earthquakes where smaller in magnitude.

There is also a developing earthquake swarm just off the coast of Gjögurtá (red dots on the image above). So far it has not resulted in any strong earthquake and its unclear if that is going to happen.
I would have written this article sooner but I fell asleep.
Please remember to support my work with donations. Thanks for the support. 🙂
During the night a minor earthquake swarm took place on two parts of the Tjörnes Fracture Zone. The first earthquake swarm was just 19,9 km north-east of Siglufjörður village. Largest earthquake in that swarm had a magnitude of 3,1.

Today (24-March-2018) at 16:32 UTC a magnitude 3,0 earthquake happened in Öræfajökull volcano. There has been a lot of smaller earthquake activity in Öræfajökull volcano in recent days and the earthquake activity has been continuous for most of that time.

I am unclear at the moment if there is any change happening at this moment. There has been slight increase in earthquakes that have magnitude larger than 1,5 in recent days. Overall there has been no major increase in earthquake activity so far in Öræfajökull volcano. But it has been mostly continuous for last several weeks and that might be a sign of trouble in near future.
The magnitude 3,0 earthquake was felt in Öræfasveit and other nearby areas.
I’ll update this article later if anything major happens.
