According to a short news today on Rúv it appears that Bárðarbunga volcano has stopped deflating and activity is slowing down in new hydrothermal vents that opened up during the most active period of Bárðarbunga volcano. The rift activity that has started in this region of Iceland is not over yet, even if there is nothing happening at current time.
It is impossible to know when next period of eruptions starts in this area. Until then it is going to remain mostly quiet.
