Volcanic eruptions have shaped life on Earth. They are also blamed as the cause of many mass extinctions in the history of the earth. Such super volcanoes can devastate entire continents and change the world climate over centuries. They erupt very rarely - the last eruption of this strength occurred over 25,000 years ago. But the danger is not averted and at some point there will be another outbreak - the only question is: when? Quarks shows how a super eruption would affect us here in Germany today and how we could deal with such a global catastrophe.
