Update on activity in Fagradalsfjall, Krýsuvík, Reykjanes volcanoes

The situation on Reykjanes peninsula is getting complicated due to activity between three volcanoes. This article is written at 15:22 UTC.

The volcanoes that are now showing activity on Reykjanes peninsula

Reykjanes volcano
Krýsuvík volcano
Fagradalsfjall volcano (added from 04-March-2021)

Fagradalsfjall volcano has no document eruption history over the last 10.000 years and the main volcano location is unknown if it exists.

Updates from the last few hours

  • Small rift valley has started to form between Keili mountain and Fagradalsfjall mountain. This is part of the rift zone that is Reykjanes peninsula.
  • Harmonic tremor stopped this morning and as Icelandic Met Office has been telling the news the origins of this harmonic tremor was earthquake activity that was so dense it created this harmonic activity. In the morning the activity dropped a little.
  • Magma continues to move in the Fagradalsfjall volcano system.
  • Earthquake activity is now between the volcanoes Reykjanes, Fagradalsfjalls and Krýsuvík. Why that is unclear but magma movement for now is only in Fagrdalsfjall volcano system.
  • Largest earthquake in last 24 hours had a magnitude of Mw4,5. Over the last 48 hours total of 72 earthquakes with magnitude over Mw3,0 have taken place. There is no sign of activity slowing down.

It is currently impossible to know for sure what happens next since this situation is extremely complicated because of all the volcanoes interactions and earthquake activity.

Update two of the earthquake swarm on Reykjanes peninsula, east of Fagradalsfjall mountain

Today (19-December-2019) at 11:20 UTC a earthquake with magnitude of Mw3,5 took place east of Fagradalsfjall mountain. This earthquake was felt in Reykjavík and nearby area. This earthquake was a continuation of the earthquake swarm that started on 15th December 2019 in this area. The activity has dropped from what was before but it is still ongoing mostly.

There are no other updates about this activity so far. I have been waiting today to see if anything more would be happening and it has not. It might happen later if anything happens at all.

Moving back to Iceland

Living in Denmark just isn’t working for me as I hoped and that is just how it is. That is why I am moving back to Iceland. It is either going to be in February or March depending on factors that I am looking into now (best price for moving my belongings to Iceland). I am not sure yet how I pay for this move since it is going to cost me around 1.091€ to 1.309€. I hope nothing higher than this amount. After this I won’t be moving away from Iceland. I am just going to stay there.
