This is a short update on the eruption in Fagradalsfjall mountain in Krýsuvík-Trölladyngja volcano system.
There are no major changes reported during the last few days. But there have been minor changes in last few days. Here the latest changes that have been reported.
- The oldest craters have stopped erupting. One of the crater has changed into a lava lake for now while the other is possible also a lava lake even if it is not visible. A lot of gas (smoke) comes from the more south crater in the crater row 1.
- There are three to four craters that continue to erupt. There seems to have been a tiny increase in the eruption today (26-April-2021). This can be explained by how few craters are currently erupting.
- No new craters have opened up in last few days. This is correct at the writing of this article.
- Harmonic tremor seems to be decreasing. It is unclear why that is since the eruption is currently ongoing.
There are no other reports about the eruption. I am not sure when next update is going to happen but it is going to be soon as possible if anything changes in the eruption.
