This is not going to be a long update since there has not been a lot of change during the last week. There has been some and this is what happened. This is part of Krýsuvík-Trölladyngja volcano system (until the studies are updated).
- The main crater is slowly closing and lava fountain activity has almost or has ended at the writing of this article.
- The main crater is now around 100 meters high. Lava depth is from 10 to 70 meters thick depending on a location. There is a map but for copyright reasons I can’t show it here.
- Lava flow is now permanent and does not happen between overflows necessary.
- Lava lake might be forming in the crater, but the status of that remains unclear at the writing of this article.
- There are overflows happening in the crater but according to the news the main lava flow happens underground in large dykes that go from the main crater into the lava field. Creating lava ponds that regularly break and expand the lava field at random.
- Today (11-June-2021) people that are idiots where seen walking on the fresh lava that has a surface temperature from 50C to 100C in order to get to the viewing area (blocked by fresh lava flows) and one did even go as far walking on the slopes of the crater and almost ending up as part of the lava field him self. Video of that can be seen here on mbl.is website. As can be seen the lava flows them self are human height and can bury a person in a few seconds time.
- Fresh lava in Fagradalsfjall is hot. While it is only 100C on the surface it can be 900C just few centimetres down and can go as high as 1100C if a surface of a lava tube is broken.
- Yesterday (10-June-2021) a change happened in the eruption and that resulted in a change in the harmonic tremor that continues. Suggesting a permanent or a long term change to the eruption. What this mean is unclear currently.
There are no other updates as is. Next update should be on 18-June-2021 unless something happens in this eruption. Other parts of Iceland are quiet at the writing of this article.
