This earthquake activity in Bárðarbunga volcano happens because of inflation that is now happening in Bárðarbunga volcano. This inflation is going to take decades to complete and in that time, this type of earthquake activity is going to be frequent with several magnitude Mw5,0 earthquake over the year, but fewer as the time goes on from last eruption (ended in February 2015). After 10 to 30 years, there is only going to be one magnitude Mw5,0 earthquake larger every few years.
