We can detect the warning signs of an eruption, but why is it still so hard to predict? Meet a few currently active hot heads: Mauna Loa, Nyiragongo, Fagradalsfjall, and Soufrière – and find out what gives them individual personalities. Plus, what a newly excavated snack bar in Pompeii, buried and preserved when Vesuvius erupted in 79 AD, can teach us about eruptions.  Guests: Christopher Jackson – Chair of Sustainable Geosciences at the University of Manchester Thorvaldur Thordarson – Professor in Volcanology and Petrology at the University of Iceland Maite Maguregui – Professor, Department of Analytical Chemistry at the University of the Basque Country, Spain Silvia Perez-Diez – Researcher in the Department of Analytical Chemistry at the University of the Basque Country, Spain Alia Wallace – Archaeologist with the Bureau of Land Management in Colorado with a PhD from University College London Jazmin Scarlett – Teaching fellow in physical geology, Newcastle University  The more than a thousand volcanoes that dapple Earth’s surface mark the edges of tectonic plates, spewing hot gas and ash, or boiling over with lava.
