b'The Earth\\u2019s surface is dappled with more than a thousand volcanoes. They mark the edges of tectonic plates, spewing hot gas and ash, and boiling over with lava. We can detect the warning signs of an eruption, but why is it still so hard to predict?\\nMeet a few currently active hot heads: Mauna Loa, Nyiragongo, Fagradalsfjall, and Soufri\\xe8re \\u2013 and find out what gives them individual personalities.
