The river Skeiđará, originating in the subglacial lake of the Grímvötn caldera, has started to increase. At present the frost in Iceland is between -2 to -20 thus glacial rivers should be at minimum. This morning, however, scientist observing that the river Skeiđará was increasing its discharge. The rivers smells strongly of sulfur and the water is loaded with sediments. It is expected that the river increases its discharge rate for the next couple of days, until it reaches its maximum of some 20.000 to 30.000 m3/s.
