Update on the eruption in Fagradalsfjall mountain on 19-April-2021

This is a short update on the eruption in Fagradalsfjall mountain that is part of Krýsuvík-Trölladyngja volcano system.

  • The crater that started erupting on 5-April-2021 has stopped erupting. I am unclear when it stopped erupting but that must have happened sometimes in last few days.
  • Smaller vents have opened up but none of them have been able to create any major eruption crater. Most of those have also stopped erupting and been buried by fresh lava from others craters when they stopped erupting.
  • Earthquake activity has been appearing along the dyke in last few hours. I am unclear what that means at the writing of this article.
  • New fissures with steam or hot air have been reported south of current eruption. I am unclear where they are located. There don’t appear to be any new fissures north of the crater that has stopped erupting at the writing of this article.
  • Crater 1 has now started to smoke a lot. While the second vent continues to erupt a smaller eruption. I am unclear on why one of the vent is smoking as it has been doing for the last few days.
  • The eruption is now 1 month old today. The eruption started on 19-March-2021.
  • Amount of lava being erupted has increased since the start of the eruption according to latest reports.

I don’t have any more reports today but that might change without warning. If that happens. I am going to write an article soon as I can.

  1. Thank your for the updates!
    I have a question. Is there a place (website) where I can see the current progress of the lava flows/lava field? Something like a map of the area with the lava colored in, that is updated regularly? I’ve seen something like that in one of your previous posts, but I haven’t been able to find an updated version.

      1. Thank You!
        That’s exactly what I was looking for (and more)! I had been looking on the IMO website, but it’s difficult to navigate the Icelandic site when you don’t speak the language (like me). Luckily translating the articles works well enough.

    I am unable to find anymore sourcing on this. May I ask who has reported it?

    1. This was reported on Facebook forum. I don’t know how accurate this report is but I estimated to be fairly correct as it was inside the magma dyke location. Nothing might happens with those fissures and they might cool down. I also included this because Icelandic Met Office and University of Iceland did cover it in the news that was also reported about this.

    1. From the ruv.is camera I can count 6 , as for the lava field during the day Iceland time it looks like the lava is not moving . The night shots show the spread much better because it shows the hot magma incandescent red. These camera’s have a habit of dying but they also have been doing a few close up shots of the vents and the front edge of the lava streams. Originally there was two cameras but the one called Meradalir died during the last storms the one called Geldingadalir also died and they did manage to get it back ( at least for now)
