No earthquake stronger than 3 magnitude have hit in or around Bárðarbunga volcano in Vatnajökull glacier since shortly before 11 am. IR photographer Páll Stefánsson shot the above picture this morning.
Páll drove to Tungnafellsjökull glacier with a view of Bárðarbunga last night and said he could feel the 4.7 and 3.5 magnitude earthquakes, but he failed to take the first picture of the eruption.
Ruv.is reports that most earthquakes occur at a depth of five to ten kilometers. Geophysicists at the Icelandic Met Office believe that the seismic activity in the Bárðarbunga caldera is connected with changes in pressure in the magma chamber below, from where magma is moving into intrusions. However, there are no indications that magma is breaking its way to the surface.
