This information is unclear, but this is the best information I have at the writing of this article.
It seems that Svartsengi volcano has reached close or the same level as 10. November levels. There has been a slight shift where the inflation has been happening. It seems to have moved slight closer towards Þorbjörn mountain, that also means the main inflation is happening closer to Sundhnúkar and Sundhnúkargígar and Sýrlingafell mountain. This strongly suggest that magma is building up in this area because of the ongoing weakness in the crust in this area. This also strongly suggests that when the magma in this sill goes next on the move, it is going to go up towards Sundhnúkar and Sundhnúkagígar area and into the dyke that formed on 10. November 2023. That dyke has filled up all available space created by the rift valley, next dyke is more likely to start an eruption than the dyke created on 10. November.
There’s no earthquake activity in Svartsengi volcano at the moment, until that happen, the volcano is quiet at the writing of this article. It is more than likely that an strong earthquake swarm is going to start in Svartsengi volcano and close to Sundhnúkar and Sundhnúkagígar once the magma gets moving again. Inflation in a volcano does not always result in increased earthquake activity, since this depends slightly on what has been happening and how the crust is in that volcano at that time when activity is ongoing. It is impossible to know when next activity starts in Svartsengi volcano, but there is a chance that the magma that has flowed into the sill needs a time to change before it moves again. That can take time, how long is difficult to know, but this might be from six months and up to two years at most. This depends on the magma flowing in, gas content and such, so it can happen both slower and faster than earlier inflow of magma into the sill in Svartsengi volcano.
At the writing of this article. Everything is quiet in Svartsengi volcano.
Something happening in Reyjanes?
You were fast at reacting, myself was fast asleep, but woke up to the information this morning.
Thanks Jon for keeping the site up to date.
Jon, you certainly gave a good prediction, that things might happen once the 10 November level was reached.
