This type of earthquake activity is so common now in Bárðarbunga volcano that I rarely bother now to write about it. This type of earthquakes now happen once to twice in Bárðarbunga volcano each week. The reason for this earthquake activity are stress changes in the caldera. This is I suspect going to take a long time, I’m looking at years of this type of earthquake activity in Bárðarbunga. What also makes this more complicated is the rifting currently taking place inside the volcano and on nearby fissures. The results of this mixture might get interesting in the future.
