Update on the eruption in Fagradalsfjall mountain on 18-June-2021

This is a short update on the eruption in Fagradalsfjall mountain. It is still classified as Krýsuvík-Trölladyngja volcano eruption. That might change in the future.

  • There is no sign of the eruption is about to stop.
  • Most of the week the lava was flowing in lava tubes that where invisible from the surface. Today (Friday 18-June-2021) that changed and lava is now again overflowing over the crater.
  • The crater remains unstable and collapses from the inside walls are frequents, or used to be. It is possible that for now the amount of lava in the crater is holding the walls up.
  • Nátthagi is now flooded with lava and the lava is on its way out of Nátthagi in next few hours to days. There won’t be any attempt made to stop the lava reaching the road or the ocean.
  • Geldingadalir valley is now full of lava and has overflowed a little. Lava might flow into Nátthagakriki in next few days, but small dirt walls where pushed up to try and delay that from happening. It is unclear if that worked. But for now the lava has not flowed into that direction.
Yellow lava flows out of the crater into a lava field and creates a new lava river.

A lot of smoke blocks the clear view into Nátthagi where the lava field is and is about to leave Nátthagi. Car can be seen at the end of the lava field.

  1. Thanks for the update. If the road is destroyed will it be a major problem for the people living nearby?

  2. Been a week, and the front of the crater is really high now. Lava sometimes comes over the surface building it up. Most of it still flowing under the crust, tho, just like the vid posted above shows.
