A glacial flood from the western melt water reservoir under the Vatnajökull ice cap is in progress. The Skafta River has been carrying up to 520 cubic meters per second discharge.
The water exiting the glacier door contains dissolved hydrogen sulfide from the volcano’s active fumaroles under the ice. So far, only the western meltwater reservoir has been involved. The larger eastern reservoir could drastically increase the flood if it gets involved as well. In that case, the significant lowering of pressure on the volcano might increase a risk of a new eruption as well.
