This morning (5-March-2022) an earthquake swarm started north of Kolbeinsey island. Three earthquakes with magnitude above Mw3,0 took place in this swarm and there where few smaller earthquakes recorded. Because of distance from the SIL network only the strongest earthquakes have been detected.
The strongest earthquakes with magnitude of Mw3,1 and Mw3,2. There is still a chance of stronger earthquakes in this area. It is unclear what is going on because this area is remote and under the ocean. If an eruption happens at this location there is a chance it won’t be noticed or just noticed on SIL seismometers.
This morning (15-April-2021) more earthquakes where recorded far north of Kolbeinsey island. This activity is probably outside of Kolbeinsey ridge but I don’t know the name for this part of the north Atlantic ride. Largest earthquake took place at 09:29 UTC and had a magnitude of mb4,4 according to EMSC. Information about the earthquake can be found here.
It is not possible to know what is going on at this location. It is extremely remote and under 2 to 4 km deep ocean. If anything more happens at this location it is only going to be detected by seismometers.
Early morning (14-April-2021) an earthquake swarm took place far north of Kolbeinsey island. Largest recorded earthquake had a magnitude of Mw3,5 but it possibly was larger but because of distance from the SIL network the magnitude is underestimated. I did record this earthquake on my only seismometers and it showed a lot of surface wave activity, suggesting a larger magnitude than Mw3,5.
Because of remote location of this earthquake swarm it is not possible to know what is going on there. The area is also under an ocean that is 2 to 4 km deep at this location. If anything happens it is not going to be noticed outside of being detected with seismometers.

Yesterday (24-January-2021) at 09:16 UTC an earthquake with magnitude Mw3,1 took place in Kolbeinsey island. Two unconfirmed earthquakes with magnitude of Mw2,5 and Mw2,6 took place at 17:37 UTC and 19:06 UTC.
The area is remote and it is difficult to know if there has been any more earthquake activity there. There is also a storm going on and has been going on for last several days and that limits detection of small and remote earthquakes in Iceland.
During the night of 3-September-2020 an earthquake swarm took place around 42 km to 50 km north of Kolbeinsey island. Because of distance from the SIL network the earthquakes that where detected do not have accurate location or magnitude.

This might just be regular earthquake activity that happens on the Kolbeinsey ridge or in Kolbeinsey island. This area is all under a deep ocean and that makes it impossible to know for sure what is going on at this location.
Today (24-January-2020) at 05:04 UTC an earthquake took place on the Reykjanes ridge. This earthquake had a magnitude of Mw3,3. This earthquake is as far away as the SIL network can detected earthquake activity in any good way and that might explain why there has not been any record of other earthquakes in this area.

There has been a lot of earthquake activity on the Reykjanes ridge in January 2020. I don’t know if that trend is going to continue or not.

Yesterday (22-May-2019) at 15:47 UTC a magnitude 3,4 earthquake took place around 12 km north of Kolbeinsey Island. This earthquake was part of a small swarm in this area yesterday. It appears to be over but there is a risk of more activity in this area. Due to distance from the coastline and next populated island this earthquake was not felt.

Earthquake swarms happen in this area frequently. This is not part of the TFZ but borders it just a little south of this earthquake activity.

If you donate with a bank please update your information. I have changed the bank information again in April and the new information can be found here. The Icelandic bank account that I have been using is going to be closed soon.
I have added a personal note on what is going on with me in the comments. It explains why I changed my mind on moving back to Denmark and other issues that I’ve been dealing with in recent months.

Today (19-October-2018) a earthquake swarm took place north of Kolbeinsey island. Due to distance from the SIL network only the largest earthquakes are being recorded.

Largest earthquake detected so far has a magnitude of 3,3 and the second largest has a magnitude of 3,0. Other earthquakes that are being detected are smaller in magnitude but all are over 2,5 in magnitude. The sensitivity of the SIL network isn’t good this far from the coastline. It is unclear if this earthquake swarm is ongoing or not.

Yesterday (8-September-2018) there was a strong earthquake swarm 88 to 90 km north of Kolbeinsey Island. Due to distance from the SIL network it is impossible to know how large and strong this earthquake swarm actually was. Largest earthquake reported by Icelandic Met Office had a magnitude of 3,3. Total of ten earthquakes with magnitude 3,0 or larger happened during this earthquake swarm.

Total around 30 earthquakes were detected but it can be assumed that total number of earthquakes might have been higher. At the distance from the SIL network smaller earthquakes are not detected. It is not possible to know for sure what is happening at this location due to distance from the coast and the SIL network.

During the night of 26-June-2017 an earthquake swarm started north of Kolbeinsey island on Kolbeinsey ridge. This earthquake swarm is located around 355 km north of Siglufjörður village making it difficult to know for sure what is going on there. Largest earthquake so far had the magnitude of mb4,4 (EMSC Information), at the moment this is the only earthquake to register with EMSC. Total of 20 earthquakes have been over magnitude 3,0 so far, as this earthquake swarm is ongoing that number is going to change in the next few hours.

I don’t know yet if there is any eruption at this location. At this distance the SIL network might not register the harmonic tremor of a small eruption or dyke intrusion. Ocean depth at this location is 2 – 3 km and that rules out any major signs appearing on the surface of the ocean. Currently there seems to be a break between earthquake swarms, that is just how it appears as the SIL network is not able to detect any small earthquakes at the distance of 355 km (about) and that means only minority of earthquakes is being recorded. There is also a possibility that this is just a normal rift earthquake activity that happens at this location, the area I think is is a rift valley, but this being a dyke or an volcano eruption can’t be ruled out.
