Volcano and earthquake activity in Iceland
Yesterday (30. January 2023) had two earthquakes with magnitude Mw3,2 far off the coast on the Reykjanes ridge. Only one smaller earthquake was detected. Distance from the SIL network makes detection of smaller earthquakes is impossible or really difficult.
Besides this earthquake activity, it remains quiet in Iceland. Bad weather has also been blocking detection of earthquake activity for the last two weeks.
Yesterday (26. December 2022) an earthquake swarm took place in Reykjanes volcano. Just on the Reykjanestá area. This earthquake swarm was mostly in the ocean and on the Reykjanes ridge but some earthquakes where on the Reykjanes peninsula on land.

Today (03-December-2022) at 12:49 UTC an earthquake with magnitude of Mw3,5 at 7,0 km depth. This was the largest earthquake in the swarm. Around of 40 earthquakes took place at the writing of this article. There are no reports about the largest earthquake was felt in nearby populated areas.
This earthquake activity suggest that a new inflation period is about to start in this part of the Reykjanes peninsula and Reykjanes ridge. There has been rather quiet time in Fagradalsfjall volcano and Reykjanes volcano since August when last eruption took place in Fagradalsfjall volcano. Reykjanes volcano has not erupted so far, but has continued activity of magma injection into the crust. When that is going to result in a eruption is impossible to know.
This evening on 16-October-2022 an strong earthquake swarm started close to Geirfugladrangur and Eldeyjarboða on the Reykjanes ridge. At the writing of this article the strongest earthquake had a magnitude of Mw4,4 but that might change without warning.
It is difficult to know how this earthquake swarm is going to evolve but there are clues in this activity that this might be a large earthquake swarm. However, activity in this area is also known to just stop without warning.
On Monday (4-July-2022) an earthquake swarm started close to Geirfugladrangur on Reykjanes ridge. Largest earthquake on Monday had a magnitude of Mw3,2 and on Tuesday a magnitude Mw3,1 earthquake took place.
This earthquake activity is what seems to be increase in earthquake activity overall on Reykjanes peninsula and on the Reykjanes ridge. The ocean is deep at this location and an eruption would have to be a big one to break up to the ocean surface because of depth in the area. I don’t know how many earthquakes have happened in this area, because of more activity on Reykjanes peninsula in last few days.
Earthquake recordings
Because of how old my hardware is and difficulty keeping it running. I have for now stopped recording earthquakes. This is going to be the situation until I can get new hardware. When that happens I don’t know. Raspberry Shake has few stations in Iceland. They can be viewed here. This is the hardware I am going to be using once I can afford to buy it. When that happens I don’t know.

Please remember to support my work with donations. I am currently really broke, because moving is expensive and I had to pay a lot of bills in July. Thanks for the support. 🙂
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.

Yesterday (20-November-2021) an large earthquake swarm started in Reykjanes volcano. This earthquake swarm is rather large, with 217 earthquakes recorded so far. Largest earthquake had a magnitude of Mw3,5 but other earthquakes have been smaller in magnitude.

Yesterday (12-October-2021) an earthquake swarm took place in Reykjanes volcano. Largest earthquake in this swarm had a magnitude of Mw3,3 and the earthquake swarm was out in the ocean not far from the coastline.
It is impossible to know for sure if this earthquake activity is directly connected to magma movements in this area. It is possible, but there have been some sign of magma moving in the crust in this area. The magma is moving but is not erupting or starting an eruption. Earthquake activity seems to be growing in this area of Reykjanes peninsula and Reykjanes ridge after the eruption in Fagradalsfjall mountain stopped.
Yesterday (11-August-2021) there was a earthquake swarm on Reykjanes ridge. This earthquake swarm was not felt because of distance from the coastline.
Largest earthquake in this swarm had a magnitude of mb4,4 according to EMSC. Information about this earthquake can be found here. The distance from the SIL network made it difficult to know when this earthquake swarm started and stopped.
It is unclear if this part of the activity period that Reykjanes peninsula and Reykjanes ridge is now entering and is going to last for few centuries.

During the night and today on 5-Augustu-2021 an earthquake swarm took place in the Reykjanes volcano.
Largest earthquake in this swarm had a magnitude of Mw3,0 and other earthquakes at the writing of this article have been smaller. That can change without warning. Currently there is a possibly that this earthquake swarm is over.
