From 20:10 to 20:14 UTC a minor dyke intrusion took place in Bárðarbunga volcano. This dyke intrusion was small, only lasting those few moments and the largest earthquake had the magnitude of 2,5. Other earthquakes are smaller. Depth was from 15,6 km to 23,2 km. Based on the location, this is clearly a dyke intrusion into Bárðarbunga volcano. It is too small to start an eruption, but suggest that magma processes in Bárðarbunga volcano are starting to increase again.

There is also a change in the SIL station Vonarskarð. What is creating remains unknown. This might be a change in hydrothermal systems under the glacier, but is impossible to know for sure at this point in time. Copyright of this image belongs to Iceland Met Office.
I don’t know if any more earthquake activity is going to take place in Bárðarbunga volcano. Since it is impossible to know what magma does next inside a volcano. At the moment I’m not expecting a eruption in Bárðarbunga volcano.
