This earthquake activity is because of inflation in Bárðarbunga volcano magma chamber. That was emptied after the eruption in 2014 – 2015 and that resulted in collapse of Bárðarbunga volcano by drop of some 60 meters. This inflation now is reversing that process slowly. It is going to be decades until Bárðarbunga volcano erupts again because of this collapse.
