Four of Iceland's main volcanoes all preparing for eruption
According to geophysicist Páll Einarsson, four of Iceland's volcanoes are showing increased amounts of activity in preparation for another eruption.
Katla is the most active that it's ever been in four decades. "Katla has been unrestful since this autumn."
The other volcanoes showing increased activity are Hekla, Grímsvötn and Bárðarbunga.
The Grímsvötn volcano is located underneath the Vatnajökull glacier. Here farmers are shown trying to save sheep from poisonous volcanic ash. Mbl.is/ Eggert Jóhannesson
