An eruption of a supervolcano in Iceland should pose as great a threat to Britain as nuclear terrorism, according to a high level UK government report.
The warning was made by a group of academics and scientists from the British Geological Survey and the Met Office, which also involved geologists from Edinburgh University.
They argue that certain types of eruptions of Icelandic volcanoes, known as effusive gas-rich eruptions, should be considered an immediate risk to human health and the environment for much of northern Europe.
They can erupt for months and cause geological devastation across thousands of miles.
The Eyjafjallajökull volcano, which erupted in 2010, is thought to be a more ‘explosive’ type as it propels ash in to the atmosphere over a shorter period of time.
While air traffic was grounded as a result, the Cabinet Office report argues the event was relatively small event, given the potentially-lethal power Icelandic volcanoes possess.
Their research touches on the catastrophic Laki eruption in 1783 which is thought to have led to the death of tens of thousands of people in Britain.
If another such eruption takes place, then Britain and other countries could be hit by a blanket of ash and toxic materials, along with several years of extreme weather.
Their claims will be aired today during a conference at the European Geosciences Union in Vienna.
