New measurements every day – Bardarbunga sulphur dioxide cloud
12 September 2014
The Bardarbunga volcano on Iceland began erupting on 31 August 2014 – an effusive eruption with no ejection of volcanic ash. However, measurements made by DLR have since indicated that there is ongoing emission of sulphur dioxide (SO2). High sulphur dioxide concentrations in the atmosphere are a clear indication of volcanic activity, as there are no other natural emission sources, only anthropogenic ones.
