New eruption threat on iceland
Geologists on Iceland are warning of the increased risk of a fresh volcanic eruption after measuring an increased swarm of earthquakes around the island's second largest volcano.

Páll Einarsson, a professor of geophysics at the University of Iceland, says the area around Bárdarbunga is showing signs of increased activity, which provides “good reason to worry”.

He told the country's national TV broadcaster Rúv a shortage of seismometer measuring devices is making it more difficult to determine the scale and likely outcome of the current shifts.

But he said there was “every reason to worry” as the sustained earthquake tremors to the north east of the remote volcano range are the strongest recorded in recent times and there was “no doubt” the lava was rising.

The geologist complained that the lack of coverage of measuring devices means he cannot accurately detect the depth and exact location of the increased number of localised earth movements.

“This is the most active areas of the country if we look at the whole country together,” he told Rúv News. “There is no doubt that lava there is slowly growing, and the seismicity of the last few days is a sign of it.

“We need better measurements because it is difficult to determine the depth of earthquakes because it is in the middle of the country and much of the area is covered with glaciers.”

Respected volcano watcher Jón Frímann, said on his volcano watch blog: “After the Eyjafjallajökull volcano eruption in the year 2010 it seems that geologists in Iceland take earthquake swarms more seriously then they did before.”

He explained the Icelandic Met Office had on Sunday warned of the increased risk of a eruption in north-west side of Vatnajökull glacier due to the high earthquake activity in the area, and added: “It is clear that only time is going to tell us if there is going to be a eruption in this area soon or not.”

The last recorded eruption of Bárdarbunga was in 1910, although volcanologists believe its last major eruption occurred in 1477 when it produced a large ash and pumice fall-out. It also produced the largest known lava flow during the past 10,000 years on earth.

It is the second largest volcano on Iceland and is directly above the mantle plume of molten rock.

By comparison, Bárdarbunga dwarves the Eyjafjallajökull volcano, which shutdown most of Europe's airspace last year after its ash cloud drifted across the continent's skies.

Warning of new icelandic volcano eruption
ICELAND’s second largest volcano looks set to blow, bringing far more chaos than last year’s eruption, ­geologists warned yesterday.

Professor Pall Einarsson, of the University of Iceland, said unprecedented tremors gave good reason to worry.

He added: “There is no doubt that lava there is slowly growing.”

Bardarbunga’s last major eruption, in 1477, shot vast clouds of ash into the air and produced the biggest lava flow of the past 10,000 years.

In comparison, the volcano which brought air traffic to a standstill last year, is tiny.

Vatnajökull is geen vulkaan, maar een gletsjer. Bárđarbunga is een berg en vulkaan die zich onder de ijskap van Vatnajökull bevindt.

Kan de berichtgeving over de vulkanen op ijsland niet beter als volgt gedaan worden?

Niet de grootse vulkaan, maar een slagje kleiner staat op springen. Niet te verwarren met de "je mag niet meer vliegen" vulkaan, die is namelijk al uitgebarsten en is ook een stuk kleiner.

Ja idd, en die vulkaan heeft dan wel weer dezelfde naam als de gletsjer (jökull) als waar ze onder zit: Eyjafjallajökull.

De Bárđabunga zit onder de Vatnajökull (Vatnagletsjer), die heeft een eigen naam want er zitten daar heel veel vulkanen.

Ondanks het gebrek aan bevingen zijn de tremormetingen wel steeds aan het veranderen, als je dat zelf in de gaten wil houden dan kun je dat op deze kaart doen, klikken op de oranje punten geeft de metingen van dat betreffende meetstation weer.

Volcano professor hits back at scare stories
The Icelandic geophysicist, Professor Pall Einarsson, whose words have caused something of an international volcano scare, says he is dumbfounded by how much his message has changed in translation. Pall Einarsson was interviewed by Icelandic broadcaster RUV in Icelandic about a series of earthquakes in the highlands.The interview was then translated and used by Britain’s Daily Telegraph, among others. Since then the message has morphed out of all recognition, Einarsson says.

“It is really strange how this news came into existence. I wasn’t even warning of a likely eruption at Bardarbunga [in the interview],” he told IceNews. “The things I emphasised in my interview with RUV’s Bjorn Malmqvist were that the earthquakes at Bardarbunga and Kistufell last week are not unusual, there are often movements there, and sometimes much bigger than this.

“In the long-term, we can see an increase in earthquake intensity at Bardarbunga. But it is still a lot less than between 1974 and 1996.

“And finally that Bardarbunga is an active volcano and could of course prove dangerous, which is why there is always reason to monitor it closely; which is why we do,” Einarsson explains.

Some foreign media sources have quoted Professor Pall Einarsson as saying that a massive eruption is about to begin that will make last year’s Eyjafjallajokull eruption seem tiny in comparison. The professor reiterates his confusion at such stories, telling IceNews that he did not say anything of the sort.

Volcanic eruptions are always possible in Iceland, Einarsson says. There have been at least 19 eruptions in just the last 40 years — the majority of which were small and caused very little damage.

Icelandic volcanoes are one of the reasons tourists visit the country and sometimes (as at Fimmvorduhals last year) the sheer number of visitors is more dangerous than the volcano itself. “There are few things more moving than to watch a volcano erupting from a safe distance,” Professor Einarsson enthuses.

Bardarbunga is located near the middle of the Icelandic ‘hot belt’. It was, however, not known as a particularly powerful volcano before 1971 when the first satellite images of the area were released. Eruptions connected to this particular volcanic system took place in 1477-80, shortly after 1700, 1862-4 and most recently in 1996. There are probably several historic eruptions missing from the list due to the sheer distance from the nearest human settlements, the professor adds. “Small eruptions at this remote volcano could easily have escaped people’s notice. They are no more dangerous than that.”
