At 21:00 UTC, the eruption plume had risen to an altitude of over 65,000 ft (~20 km). The last eruption in Grímsvötn occurred in November 2004. Grímsvötn is Iceland's most frequently erupting volcano. For further information see Update.

The Rhine River Basin
The Rhine basin (Fig. 3) covers an area of approximately 185,000 km2, distributed between
nine countries. Two third of the basin is located in Germany, whereas the alpine countries of
which Switzerland is the most important form 20% of the area (Buck et al. 1993). With its
1,320 km, of which 880 km is navigable, the Rhine is one of the longest rivers in Europe
