Earthquake activity in Öræfajökull and Kverkfjöll volcano

Since this volcanoes are in the same part of Iceland I am going to write about them in the same article.

Öræfajökull volcano

I don’t think this was a glacier earthquake activity happening in Öræfajökull volcano. I don’t know how many earthquakes took place this time around. Largest earthquakes had magnitude of 2,0 and 1,8 all other earthquakes where smaller in magnitude. Currently there is no GPS monitoring for Öræfajökull volcano that I know of.

It is noticing how this time the earthquake swarm is all on the east side of the volcano. This earthquake activity is interesting and this also seems to signal an increase in earthquake activity in Öræfajökull volcano at least for the time being. It remains a question if this activity slows down again. Earthquake activity in this part of Iceland only happens due stress changes in Öræfajökull volcano. This is most likely influx of magma into Öræfajökull volcano but it might not erupt right away or at all (at least for a long time).

Kverkfjöll volcano

A minor earthquake swarm took place in Kverkfjöll volcano today (23-September-2017). Largest earthquake in this swarm had the magnitude of 2,1 and the second strongest earthquake had a magnitude of 1,4. The earthquake swarm was in the central part of the volcano. This is the first earthquake swarm since 2015 in Kverkfjöll volcano and the activity that year was mostly due the activity happening in Bárðarbunga volcano next to it (the dike from Bárðarbunga volcano did disturb Kverkfjöll volcano). Since this earthquake activity took place everything has been quiet in Kverkfjöll volcano.

Two strong earthquakes in Bárðarbunga volcano

Today (17-September-2017) at 14:23 UTC two magnitude 3,9 earthquakes happened in Bárðarbunga volcano. This earthquake activity was at the north-east part of Bárðarbunga volcano caldera where earthquake activity has been taking place since September-2015. This earthquake activity is happening due to inflation in Bárðarbunga volcano.

Since September-2015 the rate of activity has been dropping. Now earthquake swarm happens every 11 – 18 days or so. Currently there are no clear signs that an eruption is imminent.

Small note on Þórðarhyrna volcano

On the map above a small earthquake with magnitude of 1,3 can be seen in a volcano named Þórðarhyrna. That volcano is part of Grímsfjall volcano system. Last confirmed eruption in Þórðarhyrna volcano was in the year 1902 (December) and it lasted until 12th January 1904. Not many earthquakes happen in Þórðarhyrna volcano and that suggests that an eruption might happen in this volcano without much warning. The eruption before 1902 – 1904 eruption was in 1887 and that eruption lasted until 1889. Suggesting that when eruption happen in Þórðarhyrna volcano they are long lasting and create a lot of damage as this volcano is completely covered with glacier. I make note of this because I suspect that Þórðarhyrna volcano might erupt without much warning in next few years.

Sharp increase in earthquake activity in Öræafjökull volcano

There has been increasing earthquake activity in Öræfajökull volcano in recent months. This increase is slow but it seems to be happening at faster phase to my surprise. For the first time the earthquake activity forms a direction along a fault line (it looks like a fault line) the direction of the fault line is east-west.

This was a minor earthquake activity in terms of magnitude of earthquakes happening. With largest earthquakes only having magnitude 2,2 and all other earthquakes smaller in magnitude. Last eruption in Öræfajökull volcano took place in 1727 August 3 and ended 10 months later on 1728 May 1 +- 30 days. That eruption was a VEI=4 in size. For comparison the last eruption in Grímsvötn volcano in 2011 was also a VEI=4. I don’t know how this activity in Öræfajökull volcano is going to evolve, what seems to be clear that unlike Eyjafjallajökull volcano this change is happening a lot faster in Öræfajökull volcano then in Eyjafjallajökull volcano. Those two volcanoes are comparable of structure and volcano output (Eyjafjallajökull volcano 2010 eruption was also VEI=4). If an eruption happens in Öræfajökull volcano I would expect similar flight disruption as happened during the eruption of Eyjafjallajökull volcano. At the moment, there doesn’t seems to be any major risk of eruption in Öræfajökull volcano.

Strong earthquake swarm in Bárðarbunga volcano during the night (of 7-September-2017)

During the night of 7-September-2017 strong earthquake swarm happened in Bárðarbunga volcano. Largest earthquake had the magnitude of 4,5 and the second largest earthquake had the magnitude of 4,1. Other earthquakes where smaller in magnitude. This is the strongest earthquake in Bárðarbunga volcano since August-2017.

This earthquake swarm was in north-east part of the Bárðarbunga volcano caldera. This area of the volcano has been earthquake active since August-2014 when current period of activity started. This time around no harmonic tremor was detected. That might not always be the case since it is my view that there is a risk of small short lived eruptions now in Bárðarbunga volcano with connected glacier floods. This time around it just didn’t happen.

Minor earthquake swarm on Reykjanes ridge close to Geirfuglasker island

Yesterday (22-August-2017) a minor earthquake swarm took place not far from Geirfulgasker island on the Reykjanes ridge (no GVP profile). This was a minor earthquake swarm as it was detected by Icelandic Met Office SIL network. There is a chance that more earthquakes happened then where detected. Largest earthquakes in this swarm had the magnitude of 2,4 and other earthquakes that happened where smaller in magnitude.

This earthquake swarm looks like it was mostly due to tectonic movements in this area. It is difficult to know for sure if a magma was at work here due to unclear earthquake signal. It can’t be ruled out. I don’t know when this area last erupted. I think it was sometimes in the time period between 13th and 15th century.

Update 1 on 24-August-2017

According to Rúv News the Geirfluglasker Island collapsed in 1972 but for some reason was still being used by Icelandic Met Office as a point in their system. It has now been updated to Eldeyjarboða area slightly more to the south. I will write about this are in accordance with this new information in the future.

Amazon US/Canada changes

Due to changes in Iceland bank system it is possible that I won’t be able to use Amazon US and Amazon Canada for a while. The change is that my Icelandic bank is going to stop processing checks from 1-January-2018 (along with stop issuing them). I can keep using Amazon US and Amazon Canada advertisements until October (paid by November). I have contacted Amazon US and Canada about this and the word is that Amazon US is working on this. It doesn’t seems to be the case with Amazon Canada but I don’t get much income on it anyway.

What this means at once this change takes place I will go back to getting paid only when people buy something from Amazon UK/DE/ES since with those accounts I use direct bank deposit. This means a drop in income for me since the Amazon CPM advertisement pay considerable more than the advertisement that only pay once people buy something with the Amazon UK/DE/ES banners. I just have to hope that Amazon Europe adds CPM advertisements to Amazon UK/DE/ES so I can switch to it completely. I will start switching advertisement to Amazon UK/DE/ES by November if Amazon US has not resolved the issue by then. It is going to take me few days in November to move everything advertisement from CPM to regular advertisements that only pay when something is bought trough the banners.

Update to Amazon US/Canada payment problem (after 31-December-2017)

Amazon US is looking for a solution to this problem for international associates. Since this issue is not just hitting me. Europe has in general been making checks outdated, this applies not just in Iceland and Denmark. EU even makes a special note on this on their payment information website. What I am going to do is simple. I’ll just keep collecting payments on my Amazon US and Amazon Canada accounts until a new payment system is put in place by Amazon US/Canada. I don’t know how long this is going to take, but it might take a long while until Amazon US/Canada has a new payment system in place.

Medium sized earthquake swarm in Brennisteinsfjöll volcano

Today (21-August-2017) during the night an earthquake swarm took place just east of Brennisteinsfjöll volcano. The area in question is in part inside Brennisteinsfjöll volcano fissure swarm. Part of the area is outside any known volcano. The last night earthquake swarm had some magma signature but was mostly tectonic in nature as to be expected.

Largest earthquake in this swarm had the magnitude of 2,9 and other earthquakes are smaller in magnitude. Not every earthquake has been reviewed so far due to how many earthquakes happened. Around 210 earthquakes happened in this swarm. Around 07:00 UTC the earthquake activity mostly stopped and it has been like this for several hours. It is difficult to know for sure if a new earthquake swarm is going to start in this area soon. There is nothing suggesting that an eruption is imminent, even if magma is pushing around in the ground at the moment.

Earthquake activity in Breinnisteinsfjöll volcano

Since the weekend there has been a earthquake swarm ongoing in Breinnisteinsfjöll volcano (Wikipedia link). This earthquake swarm has not been strong in magnitude of the earthquakes happening, with largest magnitude just at 2,8 and all other earthquakes being smaller in magnitude. Close to 130 earthquakes have happened so far.

The signal from this earthquake swarm shows that some of the earthquakes happening are hybrid earthquakes. That means magma is creating some of them. While tectonic process is creating others. Last eruption in this volcano was in the year 1341 and I don’t have a lot of information about it. I don’t know if this is only magma that erupts or a mix eruption (magma and ash cloud). The earthquake swam is highly localized but has moved slightly to the south from the area where it started during the weekend. The earthquake swarm appears to be ongoing as is, there are however quiet period in it and currently that is what is happening.

Minor earthquake swarm on Reykjanes ridge not far off the coast

Yesterday (14-August-2017) and today (15-August-2017) there has been a minor earthquake activity around 60 km off the coast on Reykjanes ridge. The area has a volcano (not named as such), but the area is often named after island named Eldeyjarboði.

Largest earthquake in this swarm so far had the magnitude of 2,8 and other earthquakes have been smaller in magnitude. There is a chance this earthquake swarm might increase in magnitude and number of earthquakes. The Icelandic Met Office SIL network has slight problem properly locating earthquakes at this distance (~60 km). Last eruption in this area took place on 1.May-1783 when a new island called Nýey was formed, it vanished few weeks later. Information on Wikipedia in Icelandic only (second language is Danish) can be found here.

Short analyse of events of Katla volcano 28th and 29th of July-2017

Icelandic Met Office released interesting graphs of the activity in Katla volcano during the 28th and 29th of July-2017. It gives clues to what might happen just before an eruption in Katla volcano.

Harmonic tremor pulses

On the 28th of July small and short harmonic tremor pulses appeared on SIL stations around Katla volcano. When 29th of July did come the harmonic tremor intensified considerably from what it had been the day before. The harmonic tremor pluses on 28th of July is close to impossible to see on the harmonic tremor plot on Icelandic Met Office website.


Harmonic tremor pluses as they appear on Icelandic Met Office tremor software on 28th of July-2017. Each frequency has it’s own line. Time is horizontal and intensity is vertical. Copyright of this image belongs to Icelandic Met Office.


The harmonic tremor as it is by 29th of July-2017. After midnight the activity intensifies considerably from earlier levels. Copyright of this image belongs to Icelandic Met Office.

This data suggests that before an eruption happens some type of boiling or increase in hydrothermal vents takes place in Katla volcano. This is also connected to the glacier flood that followed into Múlakvísl glacier river.

Glacier flood and harmonic tremor


Blue: Water level. Red: Conductivity. Green: Tremor activity. Values are at 10 minute central value. This data is from the SIL station at Lágu Hvolar. Copyright of this image belongs to Icelandic Met Office.

There seems to be some connection between the harmonic tremor change and the changes in the glacier flood. That suggest in my view that a minor eruption took place in Katla volcano during 28th and 29th of July. How long the eruption did last is a good question. Harmonic tremor data suggests it was only for few hours before it ended. New cracks have been seen around Cauldron 10 in Mýrdalsjökull glacier according to reports. Locations of cauldrons in Mýrdalsjökull glacier can be found here on University of Iceland Earth Science map.

That would be the end of the story in most normal years. Minor eruption and then nothing more. That does not seem to be the case this time around. Small pulses of harmonic tremor have been taking place during the week (Week 31) and that seems to be ongoing process. Most of the tremor pulses are hard to see on the SIL stations and most don’t even appear on more then one or two SIL stations. At the moment Katla volcano is quiet and that might go on for a considerable amount of time due to this minor eruption (my view) and connected glacier flood.

Magnitude 4,5 earthquake in Bárðarbunga volcano

Today (02-August-2017) a magnitude 4,5 earthquake took place in Bárðarbunga volcano. An earlier earthquake with the magnitude of 3,8 took place in Bárðarbunga volcano just moments before the larger earthquake.

Other earthquakes in this swarm where smaller in magnitude. This earthquake swarm only lasted for 30 minutes and since after that it has been quiet in Bárðarbunga volcano. Since then there has been little earthquake activity happening in Bárðarbunga volcano.

Future plan changes ahead (for me)

As many may know (or not) is that currently I am in financial problems. The worst of the problem I’m currently having are going to last until 2018 when I’m going to make small changes and slightly improve the situation for me. That is however not good enough for me in my own view. Due to that I’m going to take a little risk and make a plan change. After examining the situation for some time I’ve decided the following thing as my long run plan.

This might result in minor interference of update of this website when I move to Iceland from Denmark. Nothing major.

Next year I’ll temporary move back to Iceland. I plan on going back to school to finish learning electronic so that I can build my own electronic hardware and repair. Along with computer repairs. I don’t plan on staying in Iceland forever. For simplification what I’m going to do is the following.

1. July-2018. Move back to Iceland. Start in school in August-2018.
2. Start saving up to buy a house in Portugal. Where is not known at the moment. Finding the right place is going to take some time.
3. Finish school in Iceland (2023?).
4. Finish saving up for a house to buy in Portugal (2024?).
5. Buy house in Portugal (2024?).
6. Move from Iceland to Portugal (2024?).

This is going to take me 4 – 6 years from start to finish and in that time I’m going to stay in Iceland. I don’t have any way to do this while in Denmark for many reasons. It is better for me to do so in Iceland, even if Iceland is ~140% more expensive then Portugal as an example (Denmark is only ~51% more expensive then Portugal).

This ties into a new project that I’m planning once I’m in Portugal. Since I don’t agree with SETI method of searching for Alien life I’m just simply planning on doing it my self. With a group or people or alone doesn’t matter to me. How and where is not know at the moment since this plan is just in draft stage as is.

I’ll continue to update this website as always, even after I start searching for aliens (since it is mostly just a bot work anyway). I also plan on getting me a decent telescopes so I can take pictures of space, stars and galaxies and so on.
