There is still a powerful eruption north of Dyngjujökull and the crater is five hundred meters long, one of the most beautiful ones in Iceland, in the estimation of Ármann Höskuldsson,volcanologist. The new lava is beginning to flow over the 88 years old Thorvaldshraun and has eradicated the so-called Flæðir and the formation of a lagoon is possible there next summer.
The staff of the Institute of Earth Sciences at the University of Iceland flew to the volcano last Saturday, but photos, revealed in the news of Stöð 2, were shot by Guðbergur Davíðdsson, cameraman, during this trip. The photos included with this story at Vísir were shot by Morten S. Riishuus, a geologist at the Institute of Earth Sciences at the University of Iceland.
Ármann Höskuldsson, volcanologist, says it is obvious that the eruption has somewhat diminished since December, but the eruption has been continuous for 4 1/2 month, since the end of August.
"This is still a very powerful eruption. I think that the volcanic product is still in the range of 60 to 80 cubic meters per second, Ármann says.
Lava rivers, not visible on the surface, are visible with a thermal imaging camera under the lava shell and in some places it gushes up to the surface from these underground lava tubes. The story of Stöð 2 reveals this phenomenon.
The new lava now covers 84 square kilometers and has already eradicated the so-called Flæðir, vast stretches of sand, but melt water from the glacier used to flow there. Then it is beginning to flow over Thorvaldshraun that flowed in an eruption in Askja from 1926-1930. This means that now the lava has blocked the water that used to flow at Flæðir and Ármann thinks that the formation of a new lagoon is possible there next summer.
Then the lava pushes the branches of Jökulsá continuously more eastward and Ármann thinks that the river starts to flow in the springtime, then it will flow to the eastern branch, leading towards Kverkfjöll.
We are witnessing a great deal of changes of the landscape. The crater is unusually wide, 400-500 metres long and about 70 metres high.
"This is now one of the most beautiful craters in Iceland", Ármann says.
Stunning clips of the new crater can be seen in the video below.
The new Holuhraun lava field now covers 84.4 square km (32.2 sq mi). It is on average 10 m (33 ft) thick in the eastern part, about 12 m (39 ft) in the center, and about 14 m (46) or more in the western part according to the Icelandic Met Office (IMO).
Icelanders celebrated the new year in style with fireworks lighting up the sky all around the country.
Yesterday, the Minister of Industry and Commerce submitted a bill at Althingi on nature passes that she says will mean a drastical change of the construction of tourist attractions in Iceland.
Interestingly enough a week after publishing the list Beyonce Knowles and Jay-Z are said to have arrived in Iceland.
"It's already bigger than the entire Krafla episode,“ says Ármann Höskuldsson, volcanologist at the University of Iceland.
The Holuhraun eruption has been ongoing for almost a week now, and many photographers dream of taking photos of it, but only media photographers are allowed into the area.
