The Icelandic volcano, Katla, could be set to have its most powerful eruption in nearly a century, according an expert.
It has been monitored since a disturbance back in July, and with it’s 6.2 mile crater, an eruption could cause severe flooding if it melts the glaciers above it, the BBC has reported.
Ford Cochran, National Geographic expert on Iceland said: “This difficulty is very apparent when you compare the last two eruptions in Iceland – Eyjafjallajokull in 2010 and Grimsvotn in 2011.
“Eyjafjallajokull, which brought air traffic to a halt across Europe, was a relatively small eruption, but the unusual chemistry of the magma, the long duration and the weather pattern during the eruption made it very disruptive. ”
“There have been more than 500 tremors in and around the caldera of Katla just in the last month, which suggests the motion of magma. And that certainly suggests an eruption may be imminent.”
Iceland is unique in that it straddles two tectonic plates. The last Katla eruption in 1918 caused a huge glacier meltdown, sweeping icebergs into the ocean, producing huge amounts of water.
