The jökulhlaup (glacial outburst flood) from Grímsvötn that began near the end of October is now coming to an end. In past centuries, most jökulhlaups from Grímsvötn have entered the course of the river Skeiðará. This time, however, floodwater that emerged from beneath the eastern part of the glacier went westwards along the glacier margin and then entered the river Gígjukvísl. In the summer of 2009, the shift occurred and water has ceased to enter the course of Skeiðará.

Read moreReduced visibility (10 m) and risky weather keep visitors well away from the eruption now; all access is restriced. Lava fountains have been active both northeast of the main crater and in the old crater. Most of the lava seems to accumulate near the vents, but there are intermittent flows into the gullies of Hruná and Hvanná.
