Mayans Knew Iceland Was Going To Blow Its Roof Off and End Civilization?

Hundreds of metres under one of Iceland's largest glaciers there are signs of a looming volcanic eruption that could be one of the most powerful the country has seen in almost a century.

Mighty Katla, with its 10km (6.2 mile) crater, has the potential to cause catastrophic flooding as it melts the frozen surface of its caldera and sends billions of gallons of water surging through Iceland's east coast and into the Atlantic Ocean.

"There has been a great deal of seismic activity," says Ford Cochran, the National Geographic's expert on Iceland.

There were more than 500 tremors in and around the caldera of Katla just in October, which suggests the motion of magma.

"And that certainly suggests an eruption may be imminent...The last major eruption occurred in 1918 and caused such a large glacier meltdown that icebergs were swept into the ocean by the resulting floods.

The volume of water produced in a 1755 eruption equalled that of the world's largest rivers combined.

Thanks to the great works of historic literature known as the Sagas, Iceland's volcanic eruptions have been well documented for the last 1,000 years.

But comprehensive scientific measurements were not available in 1918, so volcanologists have no record of the type of seismic activity that led to that eruption.

All they know is that Katla usually erupts every 40 to 80 years, which suggests the next significant event is long overdue.


Katla is part of a volcanic zone that includes the Laki craters. In 1783 volcanoes in the area erupted continuously for eight months, generating so much ash, hydrogen fluoride and sulphur dioxide that it killed one in five Icelanders and half of the country's livestock.

"And it actually changed the Earth's climate," says Mr Cochran.

"Folks talk about a nuclear winter - this eruption generated enough sulphuric acid droplets that it made the atmosphere reflective, cooled the planet for an entire year or more and caused widespread famine in many places around the globe. . . .
