Today (1-March-2021) it was confirmed that Krýsuvík volcano is having a large magma injection from depth into the shallower layers of the crust. Resulting in the current earthquake swarm. At the writing of this article it seems that the magma is located at around 6 km depth. Detected displacement by GPS recordings is now more than 30cm according to the news and scientists.
The image above is from here on Facebook. What is also interesting is the activity in Reykjanes volcano. There have also been earthquakes in Reykjanes volcano but they have been fewer but not necessarily smaller in magnitude
Next article is going to be tomorrow (02-March-2021) if nothing major happens.
Update 2-March-2021 at 13:40 UTC
This morning it was confirmed that the volcano that is having a major dyke intrusion is the volcano Krýsuvík and not the volcano Reykjanes as I first thought since earthquake activity for the last 14 months has been most active in this volcano. This article has been corrected in light of this information. The border between the two volcanoes is little unclear on the map and even different between maps.
There has not been a lot of change in the earthquake activity in Reykjanes volcano. There has been a slight increase in earthquake activity compared to yesterday (28-Febrary-2021) but that increase is not a lot and only from 800 earthquakes to 1000 earthquakes for a 12 hour time period according to the news. Largest earthquake in last 24 hours had a magnitude of Mw4,9 and was felt over a wide area in West Iceland and was clearly felt in Reykjanes area.
There have now been two earthquakes outside Reykjanestá out in the ocean. A swarm of earthquakes started to appear at that location few hours ago. It is unclear what this earthquake activity means for now. This earthquake activity is something that needs to be watched since it seems to be connected for some unknown reason to the main earthquake activity on Reykjanes peninsula.
Update at 16:57 UTC
The newest earthquake has the magnitude of Mw5,1 at 16:35 UTC. This earthquake was felt over a wide area in western Iceland and all over Reykjanes peninsula.
Since I was lazy and I had not closed down my PayPal account I made a reversal in change that I had made. It is now possible to support me with PayPal donation. Donations along with advertisement income from this website help me to keep writing about earthquake and volcano activity in Iceland and try to live some type of life at the same time. Thanks for the support. 🙂
