was the largest explosive eruption in Iceland in historical time, forming
~10 km3 of silicic tephra. This eruption most likely affected ~
75% of the
country, but nearby areas were touched the hardest, where total devastation
occurred within the 20 km radios of the volcano due to large jökulhlaups
(glacial outburst floods), heavy tephra fall, and pyroclastic density currents.
