This is a short update on the eruption in Krýsuvík-Trölladyngja volcano system on 7-August-2021.
Over the last few weeks there has not been a lot to report about the eruption in Fagradalsfjall mountain. That changed tonight. The eruption seems to have entered a new stable phase. With constant eruption, rather than erupting every few hours and nothing happening for several hours after that. I don’t know if that is going to continue for long, but that is the situation at the writing of this article.
Most of the lava flow is going into Meradalir at the writing of this article. Some of the lava flow is happening underground and that lava flow is going into south-Meradalir that is just above Nátthagi valley. That can be seen as gas is now coming from that lava field and increase in gas emission shows that fresh lava is flowing under the crust of the lava. Surface lava paths can change without warning at any time.
Tourist continue to place them self in great danger by walking out in the lava field. If there is an accident there won’t be any recurse because it is going to be already too late anyway.
Update on 7-August-2021 at 13:48 UTC
Today (7-August-2021) at 08:00 UTC the eruption stopped. The harmonic tremor dropped quickly as the stop in the eruption was quick after going on for two and half day. Why this happens remains unclear. At the writing of this update at 13:49 UTC the eruption remains inactive.
