Grimsvotn Eruption, Iceland

photo of Grimsvotn Eruption, Iceland

Grimsvotn Eruption, Iceland. From December 18 to 28, 1998 a 1300-meter-long fissure eruption took place on the south edge of Grimsvotn Caldera, much of which is buried beneath the Vatnajokull Ice Cap. The ash and steam column reached heights of 10 kilometers. This eruption occurred 10 kilometers south of the 1996 Gjalp subglacial eruption that melted 3 cubic kilometers of ice, causing a huge glacial outburst flood that destroyed the road and communication lines across southern Iceland.
