Virkniyfirlit:
The recent glacial outburst flood (jökulhlaup) from Grímsvötn has peaked in the river Gígjukvísl. The aviation colour-code for Grímsvötn was increased temporarily to reflect the increased likelihood of a volcanic eruption due to pressure-related changes while meltwater drained from Grímsvötn. Now that the jökulhlaup has ended, and there are no measurable signs of short-term, elevated activity, the aviation colour-code has been returned back to green.
