As a result the caldera under the Dyngjujökull glacier is now comparable to some of the most famous volcanic eruptions in human history, for example the Vesuvius eruption in 79 A.D. that destroyed the city of Pompeii and the eruption of St. Helens in 1980 in Washington State in the U.S. which killed 57 people.
The VEI was made by the U.S. Geological Survey and is based on the volume of volcanic products from the eruption. In the next category above, VEI 6, we find the Krakatoa eruption of 1883 and the Pinatubo eruption of 1991. Above that, in VEI 7, we have the Tambora Eruption of 1815, the most destructive eruption in the recorded history of mankind. Mankind has yet to witness a VEI 8 eruption, the highest category there is, but among those is counted an eruption under Yellowstone Park which is believed to have occurred around 640 thousand years ago.
In the next category below, VEI 4, we can find many known eruptions, among them the Eyjafjallajökull eruption of 2010.
On September 14th 1950 the plane Geysir went on its last voyage.
Scientists at the Institute of Earth Sciences at the University of Iceland are still very much at work at the lava field Holuhraun north of Vatnajökull. They have released a video which shows them transferring burning hot lava into a pot and cooling it with water.
"It's already bigger than the entire Krafla episode,“ says Ármann Höskuldsson, volcanologist at the University of Iceland.
It was noticed blowing all around the fissure, but no one could explain or understand why. It looks like tufts of hair and feels like glass wool.
The lavaflow from the caldera is equal to the waterflow of the Þjórsá river.
