This earthquake activity is located in the south part of the Bárðarbunga volcano caldera. Not far from cauldrons (at least two) that are now highly active in hydrothermal activity. If that is going to result in any glacier flood is not known at the moment, but the biggest chance is that the water levels are low at this locations at least for now. After the magnitude 4,1 the earthquake activity has stopped for now.
