Earthquake swarm close to Geirfugladrangur on Reykjanes Ridge

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.

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.

Earthquake swarm in Reykjanes volcano

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.

Two green stars out in the ocean shows the location of the earthquake swarm that was happening on Reykjanes ridge in the volcano of Reykjanes. Green star is also close to Keilir volcano that had an activity yesterday also.

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.

Earthquake activity on the Reykjanes ridge

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.

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.

Strong earthquake swarm ongoing on Reykjanes ridge

At midnight on 1-August-2021 an earthquake swarm seems to have started deep on the Reykjanes ridge. The current distance seems to be around 220 km away from Reykjavík or 190 km from Grindavík town. At this distance the location from Icelandic Met Office are not accurate. At the writing of this article the earthquake swarm seems to be ongoing.

Largest earthquake recorded at the writing of this article had a magnitude of Mw5,2 and the rest of the earthquakes have magnitude between Mw4,0 and Mw4,8. Overview of this earthquake activity can be found here on EMSC website. This links works as I publish this article. How long it is going to work I don’t know.

The current distance makes it impossible to know for sure what is going on at this location. The pattern of this earthquake activity suggests that this might be earthquake activity because of magma movement in the crust, but there is not any way to confirm this because of the location. Even if there is an eruption at this location it won’t make any difference to the surface of the ocean, since depth of the ocean at this location is more than 1 km. I don’t know the exact depth.
