After several weeks of quiet period, activity in the volcanoes that are close to or in Vatnajökull glacier. During the past few days there have been earthquakes in several volcanoes in Vatnajökull volcano. Today it is the Hamarinn volcano and Kverkfjöll volcano.
Hamarinn volcano (Loki-Fögrufjöll)
Hamarinn volcano had its first eruption in July 2011. This eruption was small and started without even a hit of earthquake activity. It created a glacier flood that topped at 2100 M3. It did not create any damge. But it filled a human made lake that is used for power production in this area. That eruption was short, it only lasted for about 24 hours, maybe even less. Today this area of Hamarinn volcano has been having minor earthquake swarm. But this does not mean it is going to erupt again. But it also shows that current activity in Hamarinn volcano is not over.

Kverkfjöll volcano have been warning up to a eruption for some time now. When they might erupt is impossible to know at current time. But it is save to say that at present time, no eruption is going to take place any time soon. This however means that earthquakes are increasing in Kverkfjöll volcano. Most of the time there are just small earthquake swarms in Kverkfjöll volcano. No other changes have so far been noticed in Kverkfjöll volcano. But that is unlike what has been taking place in Askja volcano in the past few weeks.

After several weeks of quiet in Iceland it seems to be that the quiet period is over. But if it is going to going to result in any major activity is impossible to know at this point.
