Bardarbunga volcano (Iceland): ongoing seismic unrest

Ever since the large Holuhraun fissure eruption (Aug 2014-Mar 2015), the volcano has remained restless. Over the past months, the volcano's seismic activity has been showing a slow increase.
Earthquakes under and near Bardarbunga volcano during the past week
The quakes have been concentrated at shallow depths under its central caldera, and the northeastern fissure system (in particular, near Herdubreid volcano). So far, the frequent earthquake swarms have been small and rarely contained quakes above magnitude 3; an eruption in a very near future seems unlikely for now.
However, they indicate that the volcano's storage system is probably recharging with new shallow magma intrusions; a new eruption of Bardarbunga in a not too distant future (months to years) would certainly not be a big surprise.

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. ... Read all

Bardarbunga volcano (Iceland) - Smithsonian / USGS Weekly Volcanic Activity Report for 22 April-28 April 2015 (Continuing Activity)
On 26 April the Icelandic Met Office (IMO) lowered the Aviation Color Code for Bárdarbunga to Green (the lowest on a four-color scale). No further signs of unrest had been noted since the end of the eruption on 27 February; seismicity within the caldera and the associated dyke intrusion continued to decline. ... Read all
