It was reported by Icelandic Met Office at 22:20 UTC that people had been noticing more gas smell close to a small lake called Grænavatn. This suggest that magma might be on the move in the crust. It is currently difficult to be sure at writing of this article. This would be inside the volcano of Reykjanes.
At the writing of this article there has not been any change in harmonic tremor on nearby SIL stations. If magma is about to move that is possibly going to happen without much warning but this difficult to know for sure at the writing of this article.
