Two earthquakes with magnitude above 3,0 have taken place in Bárðarbunga volcano. The earlier earthquake had the magnitude of 3,8 and the second earthquake had the magnitude of 3,8. Other minor earthquakes also happened.
This type of earthquake activity in Bárðarbunga volcano has been going on for months already. What has mostly changed over the last four months is the magnitude of the earthquakes. The rate they are happening is about the same at the moment, once to twice a week currently. I don’t expect this to change until it does.
