At about 3 a.m. this morning (16 August), an earthquake swarm began by Bárðarbunga volcano in NW Vatnajökull ice cap.
Ongoing magma movement in Bárðarbunga for the past days have raised questions of possible flight disruptions between Iceland and Europe.
Seismologists at the Icelandic Meteorological Office (IMO) have reclassified the earthquake close to the Bardarbunga volcano last night.
Over the last seven years seismic activity has been gradually increasing in Bardarbunga and the fissure swarm north of the volcano.
All highland roads north of Vatnajökull glacier have been closed and all traffic banned, whether by vehicle or on foot. The Bárðarbunga situation is now attracting worldwide attention on a scale similar to the Eyjafjallajökull eruption in 2010.
Of these around 950 have occured since midnight today. Several of these events were larger than magnitude 3.
The seismic activity in Bardarbunga on the Vatnajokull glacier is very powerful and therefore full reason to expect a volcanic eruption according to a specialist at The Icelandic Meteorological Office. A live webcam has been placed in the vicinity of Bardarbunga.
