Iceland volcano: why we were lucky we weren't wiped out | World news | The Guardian

The map is almost uncannily similar to today's: a spray of black dots showing the recorded sightings of a foul grey haze spreading across Europe, from Helsinki to Naples, from Heligoland to Mallorca, and reaching eventually to Aleppo and Damascus – and all of it caused by clouds of ash from an immense volcano erupting far across the sea in Iceland.

But this was a map made from data collected in 1783. The volcano was called Laki, it erupted for eight dismal months without cease, ruined crops, lowered temperatures and drastically altered the weather. It killed 9,000 people, drenched the European forests in acid rain, caused skin lesions in children and the deaths of millions of cattle. And, by one account, it was a contributing factor (because of the hunger-inducing famines) to the outbreak six years later of the French revolution.

Great volcanoes have a habit of prompting profound changes to the world – very much greater in extent than the most savage of earthquakes and tsunamis, even though the immediate lethality of the latter is invariably much more cruel. Though ground-shaking events are generally fairly local in extent, their potential for killing can be terrific: 250,000 died after the Tangshan earthquake in China in 1975; and a similar number died in the Indian ocean tsunami of 2004. Volcanoes seem by contrast relatively benign: the accumulated total number of deaths in all of the great volcanoes of the last 300 years has probably not exceeded a quarter of a million: the total number of casualties from a hundred of the biggest recent eruptions has been no more than those from a single giant earthquake.

But there is a signal difference. Earthquakes and their aftershocks, once done, are done. Volcanoes, however, often trigger long-term and long-distance ill-effects, which history indicates generally far outweigh their immediate rain of death and destruction. Emanations of particles from the tiniest pinprick in the earth's crust, once lifted high into the skies by an explosive eruption, can wind themselves sinuously and menacingly around the entire planet, and leave all kinds of devastation in their train. They can disrupt and pollute and poison; they can darken skies and cause devastating changes in the weather; they can and do bring about the abrupt end to the existence of entire populations of animals and people.

Earthquakes and tsunamis have never been known to cause extinctions; but volcanoes and asteroid collisions have done so repeatedly – and since the earth is today still peppered with scores of thousands of volcanoes ever yearning to erupt, they and the dramatic long-term effects of their eruptions are in fact far more frequent, far more decisive, and far greater than those that are triggered by any other natural phenomenon on the planet.

It is worth remembering that ours is a world essentially made from and by volcanoes. They are creatures that will continue to do their business over the aeons, quite careless of the fate of the myriad varieties of life that teems beneath them and on their flanks. Including, of course, ours.

Iceland prepares for second, more devastating volcanic eruption - Times Online

via timesonline.co.uk

The original fear was that the volcano had erupted directly underneath the Eyjafjallajokull glacier, which could have caused glacial melt, flooding and mudslides. Instead, the volcano blew inbetween Eyjafjallajokull and the larger Myrdalsjoekull glacier.
However, the danger is that the small volcano is just the beginning and that it will trigger the far more powerful volcano of Katla, which nestles beneath Myrdalsjoekull.
“That has to be on the table at the moment," Dave McGarvie, senior lecturer at the Volcano Dynamics Group of the Open University, said. “And it is a much nastier piece of work.”
Icelanders agree. "This could trigger Katla, which is a vicious volcano that could cause both local and global damage," Pall Einarsson, from the University of Iceland, said.
Tremors around Eyjafjallajokull were first recorded in early March, but precise prediction of volcanic eruption is difficult, even with the high-tech equipment available to Icelandic geologists.
Now that it has happened the only basis for prediction is history — and that does not look good.
"Eyjafjallajokull has blown three times in the past thousand years," Dr McGarvie told The Times, "in 920AD, in 1612 and between 1821 and 1823. Each time it set off Katla." The likelihood of Katla blowing could become clear "in a few weeks or a few months", he said.
Iceland is built on a volcanic rock on the Atlantic's mid-oceanic ridge and it has grown used to eruptions. The southern village of Vik, close to the current eruption, has for centuries had an escape plan in which everybody runs up to the church, which is built on high ground. They know that if Katla erupts flooding will follow.
The island's worst eruption in modern times was in 1783, when the Laki volcano blew its top. The lava shot to heights of 1.4 kilometres and more than 120 million tonnes of sulphur dioxide was released into the atmosphere.
A quarter of the island's population died in the resulting famine and it transformed the world, creating Britain's notorious "sand summer", casting a toxic cloud over Prague, playing havoc with harvests in France — sometimes seen as a contributory factor in the French Revolution — and changing the climate so dramatically that New Jersey recorded its largest snowfall and Egypt one of its most enduring droughts.

UK Siezes Strategic Assets in Iceland Bank Collapses

Chancellor of the Exchequer, Alistair Darling said the UK depositors should not worry about the collapse of Iceland's Banks. We have siezed a strategic stake in Iceland's Icebergs. Despite global warming, we should be good until the next election, he said.
