Update on the eruption in Fagradalsfjall mountain on 30-April-2021

This is a short update on the eruption in Fagradalsfjall mountain on 30-April-2021.

There has not been any major changes since last update. This are the noticeable changes since last update in the eruption in Krýsuvík-Trölladyngja volcano system.

  • Just one crater is now erupting. All other craters have stopped erupting but for now some of them might contain lava lake for now that might be creating a flow in lava tubes under the surface in the lava field. This process might not be visible on the surface.
  • A lot of activity now is in form of high lava arcs (correct word?) are now being formed in the one crater because of increased gas content of the lava.
  • Lava fields are slowly filling up all nearby valleys that it is flowing into. This is a slow process and is going to take months.
  • There are no signs the eruption is about to end.

No other updates have been reported so far. Rúv has installed a new web camera to give better view of the eruption. That camera can be found on YouTube Rúv channel.

Vacation

I am going on a small vacation between 5th May and 10th May. That means next update about the eruption is going to be on 14th May. I don’t know if I can go to the eruption yet as that depends on the weather and the weather is always unstable in Iceland.

  1. Jón, many thanks for your update, and wishing you an enjoyable vacation – let’s hope you get to see the eruption.

  2. Hey have fun and if you visit the sit just dont get tooo close please!

  3. Well, the eruption has become a bit more unique. It erupts for 7-12 min, then pauses for 2-3 min. When the eruption starts again, its rather large for 10 sec or so. Acting like a geyser. This started last night, and now a couple different areas are steaming. Various cams picking this up. Guess we shall see if another vent forms.

  4. I think the correct word is “lava fountain “ but you are doing good.
