Review

When the Icelandic volcano Eyjafjallajokull erupted in 2010 it created transport chaos across the northern hemisphere. But according to geologist Martin Pepper, that was a mere "party-popper" compared with some of its "monster" neighbours. The most volatile of these monsters is Eyjaf's neighbour Katla, which is way, way bigger.

Pepper and Liz Bonnin are trekking (and diving, and off-road driving, and rafting) across Iceland as they explore all the elements that make the island's volcanoes so lethal. One, Laki, which erupted in 1783, might have caused up to a million deaths, mainly as a result of a sulphuric haze that blocked the Sun's light and caused terrible droughts in north Africa and India.

And all the time, Katla is expanding and starting to melt its icy covering. One of its scientific monitors even admits that she's scared by what it might do.…

Summary

Martin Pepper and Liz Bonin explore Iceland to see whether its volcanos could cause chaos in the future. Plus, a look at a motorsport that takes place on ashy slopes.
