New Icelandic volcano eruption could have global impact
Hundreds of metres under
one of Iceland's largest glaciers there are signs of an imminent
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.
