After the large eruption in Grímsfjall volcano in May 2011 there are going to be few more years until next eruption in Grímsfjall volcano. When that happens is impossible to know.

I am sorry for lack of updates in recent days. I have been moving and taking up from boxes and that stuff takes time and energy. I have now temporarily fixed the geophone in Hvammstangi, Iceland and that is now updating again. The geophone website can be found here.
Overview of the Reykjanes volcano activity in recent days
In general there has not been a lot of change in activity in Reykjanes volcano. Earthquake activity has most stopped north-east of Gridavík town when the inflation in that area mostly stopped and a little time of deflation started and stopped at 55mm based on recent GPS measurements. Earthquake activity is ongoing. There seems to be a pattern of larger earthquakes happening in the western part of the activity in similar pattern as was the case in the eastern part of the active area (Grindavík town). Largest earthquakes on Wednesday had a magnitude of Mw3,4. There is a risk of stronger earthquakes in this area.

This information might go outdated quickly if something happens in this area. Earthquake activity might be increasing again with Grindavík town but that is unclear at the writing of this article.
