It is unclear what is going on in Grímsfjall volcano at this moment. Harmonic tremor level continue to rise. They are currently way above what is normal for minor glacier floods from Grímsfjall volcano. This might be a minor eruption, or it might just be glacier on the move inside caldera. Whatever it is. This is not a strong event. As it only appears so far on only one SIL station. The one located on top of Grímsfjall volcano. Other SIL stations do not show any change so far. There is no earthquake activity in Grímsfjall volcano so far following this activity.

So far nothing there is no word from Icelandic Meteorological Office on what is going on in Grímsfjall volcano. I am also uncertain what is going on in Grímsfjall volcano at present time. But I am sure that is going to get clearer in the next few hours. The harmonic tremor level appears to be continue to rise. So it might get confirmed in the next few hours if there is an eruption in Grímsfjall volcano or not.
I have changed my mind on taking the geophone network down. The main reason being that data is valuable. The data that I am collecting today has value. I did not release this until this morning. After I had been telling the person who hosts my Hvammstangi geophone that data has value yesterday. This is also true for my geophone network. But it is going to cost me a lot to keep it running as is. The largest cost being maintenance and internet cost over 3G (2190 ISK, 13,41€ a month pr. 3G connection where that is used).
But this is it. My geophone network is going to stay up until I can replace it with a better network in the future. When that is going to happen I do not know. But I hope it is going to take me less then 10 years until I can start to implement that plan.
