Radio Times: Review by:; Gill Crawford

As disruptive volcanos go, Iceland’s Eyjafjallajokull is a doozy. When it erupted in April 2010, spewing ash and vapour into the sky, it stopped flights across Europe and caused havoc for millions. But in terms of the volcanic history of Iceland, it was actually quite a minor eruption: there are potentially much more troublesome volcanos ready to blow.

This stunningly photographed series returns with a survey of Grimsvotn (whose eruptions occur 2000ft below a glacial cap and aren’t seen on the ground at all), Askja, Hekla and Katla, all different, all likely to erupt within the next few decades, and all much easier to pronounce.
