With 130 volcanoes – both active and inactive – Iceland is one of the most intensely volcanic places in the world.
An expert has now warned that four of the country’s biggest volcanoes are priming to erupt, which could lead to travel chaos.
The volcanoes in question are Katla, Hekla, Bárðarbunga and Grímsvötn – three of which have already erupted in the last 20 years.
The warning follows the 2010’s explosive eruption of Icelandic volcano Eyjafjallajökull, which caused more than 10 million air passengers to be stranded and cost the European economy an estimated £4 billion ($4.9 billion).

Pall Einarsson, a geophysicist at the University of Iceland, Reykjavik told Iceland Monitor: ‘Four of Iceland’s volcanoes are showing increased amounts of activity in preparation for another eruption.’
Katla is the least recently-active volcano of the four, which last erupted in 1918.
But according to the Global Volcanism Program, Katla has been showing signs of restlessness recently, with tremors in September exceeding the magnitude three mark.
This level of tremor could be enough to send magma upwards through the crust, and cause it to burst through the surface.
