This information is going to get outdated quickly. This article covers Krýsuvík-Trölladyngja volcano. This article is written on 21-March-2021 at at 00:40 UTC.

  • This eruption is tiny. The amount of magma erupted is now around 0.02km3 but this number might not be fully accurate since I’ve not seen any published number about of volume of lava erupted so far.
  • This is unconfirmed but it is possible that an new fissure opened up under the lava field next to the hill side (seen on the web camera, this is on the left side).
  • The current erupting fissure is now about 200 meters long and might be getting shorter.
  • Earthquake activity has almost stopped at the writing of this article.
  • This eruption might only last 1 to 3 days before it stops.
  • There is no sign of deflation in the GPS data at the writing of this article.

There are no other reports about this eruption at current time. This might change without warning.

    1. Yes, but i am not so sure it will stay so. Fissure eruptions can expand and grow. But it can also stay small.
