Over the past few months there has been a considerable decrease in earthquakes happening in Bárðarbunga volcano. Now earthquakes don’t appear weekly or every 14 days as was the case for a long time. Now a strong earthquake with magnitude above 3,5 or above 4,0 happens once a month or twice a month as is the case for August-2017. This brings up the question of Bárðarbunga volcano is getting close to being fully inflated again since the eruption in Holuhraun ended in February-2015.
