Incredible Nature

An eruption at the Katla volcano would be ten times stronger and shoot higher and larger plumes of ash into the air than its smaller neighbour.
Katla is buried under one of Iceland's largest glaciers, the Myrdalsjokull, which is 500m deep.
This means it has more than twice the amount of ice than the current eruption has burned through, threatening a new and possibly longer aviation standstill across Europe.
