Bardarbunga volcano (Iceland): continuing earthquakes and unrest

Earthquakes under and near Bardarbunga volcano since Jan 2016 (yellow circles = older than 2 days, red = past 48 hours)
Over the past few months, seismic activity at the volcano, mainly under the volcano's large, ice-covered caldera has been increasing again, suggesting that magma might be filling the volcano's reservoir underneath the caldera.
Time vs depth of earthquakes since 1 Jan 2016
Since the beginning of the year, more than 300 shallow earthquakes of magnitudes up to 3.8 on the Richter scale were recorded, clustered in areas near the southern and northeastern caldera rim.
Another cluster of small earthquakes concentrates along the 2014-15 eruptive dyke 20 km to the NE of the volcano.
Whether or not, and if so, when the observed earthquake activity under the caldera could lead to another eruption of the volcano, now considered one of, if not even THE most active in Iceland, is impossible to predict.
