The Campi Flegrei volcano in Italy has become weaker and more prone to rupturing, suggests a new study. The energy of the volcano is such that its eruption 30,000 years ago would have contributed to the extinction of Neanderthals.
A surge in activity in the early 1980s led to the evacuation of 40,000 residents, but the volcano has not been talked about since then. The probability of a mega eruption is however "very low", tempers Stefano Carlino of the Italian Institute of Geophysics and Vulcanology.
