Strong earthquake in Nátthagakriki south-west of Fagradalsfjall volcano

Currently I can only post articles limited. This is going to be the situation until 5th of July when I get internet connection in Denmark.

Today (8-June-2022) at 05:04 UTC an earthquake with magnitude of Mw3,0 took place in Nátthagakriki that is south-west of Fagradalsfjall volcano. It has been followed by smaller earthquakes with shallow depth of 2 km. It is unclear what is going on and no changes have been seen on GPS monitoring in the last few days for this area.

Older data already shows that magma is flowing into an area of the crust below Fagradalsfjall volcano (mountain). When that might erupt is impossible to know. It is also not possible to know when next cycle of earthquakes and eruptions starts in Krýsuvík-Trölladyngja volcano system.

Updates start again from 5-July-2022

In the recent weeks I have been moving to Denmark from Iceland. This is a process that takes time and limits what I can do for the next few days. I no longer have a seismometer in Iceland since running it from Iceland proved to be an impossible task. It is also made more difficult by the fact that hardware and the software that I have is old and no longer maintained.

I don’t know when I can afford upgrading to a new hardware. It is going to take a while until that happens. I am going to have my own seismometer in Denmark. That is going to allow me to record strong earthquakes in the Mediterranean sea area.

Those who want to monitor live earthquake detection in Iceland can do so on Raspberry Shake website here. My normal seismometer can be viewed here, once it’s back online on the internet. I already have the seismometer it self up and running, but I have some work left until everything is connected again. I also have to wait for a new internet connection in Denmark. I have to wait for that for a while, but I hope to have Danish internet connection by end of June at the latest.

I won’t post this article on social media.

Update 08-June-2022

According to the internet company that I did order my internet from in Denmark. I’ll not get an internet connection until 5-July-2022. Until then, updates are going to be limited.

Donations

Since moving and everything around it is horribly expensive I need donations to survive the month of June. That allows me to survive the month of June and until my situation starts to get more stable. If you donate by bank, please update your information to the Danish bank account. Thanks for the support. 🙂

Strong earthquake in Bárðarbunga volcano this morning

Today (28-May-2022) at 08:06 UTC an earthquake with magnitude of Mw4,4 or Mw4,7 (EMSC information can be found here) took place in Bárðarbunga volcano.

This earthquake activity is because of inflation in Bárðarbunga volcano magma chamber. That was emptied after the eruption in 2014 – 2015 and that resulted in collapse of Bárðarbunga volcano by drop of some 60 meters. This inflation now is reversing that process slowly. It is going to be decades until Bárðarbunga volcano erupts again because of this collapse.

On Thursday 26-may-2022 there was a strong earthquake on Reykjanes ridge

On Thursday 26-May-2022 at 20:11 UTC an earthquake with magnitude of Mw3,5. I think this earthquake was maybe felt in populated areas closest to the earthquake. This earthquake was out in the ocean, a good distance from land.

This earthquake possibly is part of the earthquake activity that is happening in Reykjanes peninsula and Reykjanes ridge. It is more difficult to know what is going on in the ocean, than on land.

Posts are going to get delayed for the next few days because I am moving to Denmark.

Earthquake swarm north of Geysir

Today (24-May-2022) an earthquake swarm started north of Geysir. This earthquake swarm is mostly small and only around 40 earthquakes have been recorded so far. Largest earthquake had a magnitude of Mw2,8 and all other earthquakes have been smaller.

This earthquake activity is normal tectonic activity and I am not expecting anything more to happen. Larger earthquakes might happen, but at the writing of this article it seems unlikely. This area also has regular earthquake swarms.

Strong earthquake this morning north-east of Grindavík town

Today (23-May-2022) at 07:14 UTC an earthquake with magnitude of Mw3,5 took place north-east of Grindavík town. This earthquake was felt in Grindavík and in Reykjavík. The earthquake was located in a area that is either inflating or on the edge of area that is inflating.

Green stars both north-east and north-west of Grindavík town along with several orange dots that show smaller earthquakes in the area

According to Icelandic Met Office news, the inflation around Þorbjörn mountain since the start of this earthquake activity is currently at 45mm. I don’t know how much inflation the crust can take in this area before an eruption starts in this area. Any eruption in this area is probably going to start with few craters that shut down with time and then there is just one crater that erupts until the eruption ends.

Ongoing earthquake swarm north of Grindavík town wakes up people

Today (22-May-2022) at 09:53 and 09:57 UTC earthquakes with magnitude of Mw3,5 and Mw3,6 took place north-west of Grindavík town. This earthquake was felt and did wake up people according to the news.

There is no signs that this earthquake activity is slowing down. It does come in waves according to Icelandic Met Office. This means that there are period of high activity with low activity between. Currently, at the writing of this article, there is a low activity period ongoing.

Increased earthquake activity off the coast of Reykjanestá

Today (20-May-2022) around 18:00 UTC the earthquake activity off the coast of Reykjanestá, that is part of Reykjanes volcano, increased again after few days of little earthquake activity. The earthquake swarm is ongoing and always changing so this article is going to be short because of that.

Largest earthquake so far had a magnitude of Mw3,8 and the second largest earthquake had a magnitude of Mw3,5. The Mw3,8 earthquake was felt in Grindavík and on nearby towns on Reykjanes peninsula. A Mw3,0 earthquake took place just north of Grindavík and was felt in the town.

Small earthquake swarm in Hengill volcano

Today (20-May-2022) at 15:45 UTC an earthquake with magnitude of Mw3,1 took place in Hengill volcano. I don’t know if this earthquake was felt.

At the the writing of this article there has not been any more activity in this area. That might change without warning.

Earthquake activity in Hofsjökull volcano

Today (20-May-2022) at 15:24 UTC an earthquake with magnitude of Mw3,2 took place in Hofsjökull volcano. Two smaller earthquakes had happened before the larger earthquake.

There is no other earthquake activity following this. Earthquakes are rare in Hofsjökull volcano but they do happen every few years. There are no signs of any other activity in Hofsjökull volcano.
