Brian Cox and Robin Ince find out if supervolcanoes are worth worrying about. They are joined by volcanologist Tamsin Mather, geologist Chris Jackson and comedian Rachel Parris. They learn about the worst eruptions of all time, including the eruption that may have sparked the French Revolution. They find out what volcanologists like Tamsin are doing to monitor supervolcanoes and if volcanologists do predict an impending eruption, is there anything we can do about it? New episodes are released on Saturdays. If you're in the UK, listen to the full series first on BBC Sounds: bbc.in/3K3JzyFProducer: Caroline Steel Executive Producer: Alexandra Feachem
