This is a short update on the eruption in Fagradalsfjall mountain that is currently erupting and is part of Krýsuvík-Trölladyngja volcano system.
- There have not been any major changes since last update. Minor changes seems to be happening but at the writing of this article, those changes have remained small.
- Large lava fountain activity has stopped in later part of this week. There is still some lava fountain activity going on but it is minor based on what I’ve seen on the web cameras.
- Lava is now flowing into Nátthagi. It is expected to reach Suðurstandarvegur road in 20 to 60 days depending on the lava flow into Nátthagi.
- The western barrier for the lava has stopped the lava flow into Nátthagi at the writing of this article. Bad weather today (28-May-2021) has prevented any observation of the current situation in the eruption area. Its fog and heavy rain in this location currently.
- Lava reservoir have formed in the lava field. They fill up slowly and then empty them self quickly into the lava field both on surface and with lava tubes that have formed in the lava field. This allows the lava field to expand quickly and without warning into new areas.
- The lava field is slowly building upwards from the height it has been in recent weeks. Results of this is that soon the walking path to the viewing area on the ridge might soon be blocked by lava going over the area at its lowest points. This might only take few weeks to happen but that depends on how quickly the lava field builds up.
Other then this there has not been a lot of change in the eruption. This phase of the eruption might go on for months. There are clues that this is the first step in the building of a shield volcano or maybe a stratovolcano. What happens is a wait and see on this eruption.
