Scientists warn of possible eruption of Europe's dangerous 'supervolcano'.

The Campi Flegrei supervolcano in Italy is showing signs of potential eruption for the first time since 1538, with its crust becoming weaker and more prone to rupturing, according to a new study. The consequences of an eruption could be catastrophic, with the potential to unleash tsunamis, toxic ash and sulphur that could cause global winter for years, killing crops and causing mass extinctions. While scientists say a gigantic eruption is not inevitable, they warn that the 1.5 million people living above the volcano complex should be prepared for all outcomes.
