This is a short update and this information can go out of date quickly and without warning.
- Earthquake activity continues in Svartsengi and close to Þorbjörn mountain. This earthquake activity is either tension earthquakes because of the dyke on either side (north-east and south-west) or in the dyke it self.
- Inflation in Svartsengi and nearby area is extremely high and has been increasing much as 10mm a day in last few days.
- There has been magma building up in the crust in the Reykjanes volcano since at least year 2020. It might have started few years earlier at more depth, but that is unclear.
- There’s a risk of large eruption in this area, that might go on for few months in the worst case.
- Largest earthquakes so far have had the magnitude of Mw4,7. Larger earthquakes remain a possibility.
- It is impossible to know when a eruption starts or if it starts. But the likelihood of an eruption is extremely high.
- Morgunblaðið reported that ground heat has been seen on thermal cameras. The news can be found about this here in Icelandic. There’s a YouTube video of this in both Icelandic and English (with more footage).
I’ll post new information about what is going on when it happens. As is, the situation does not change a lot from one day to another so I don’t have a lot to report on.
