Supervolcano responsible for largest eruption in European history has started to stir again


THE Campi Flegrei caldera under the Italian city of Naples shows signs of “reawakening” after almost 500 years of inactivity.

According to a study published Tuesday, it is close to nearing a critical pressure point, which could spell disaster for the 500,000 people that reside in the area.

The 12km-wide cauldron is actually a collapsed volcano. As such it does not have one obvious central peak, rather it is fuelled by one huge magma chamber. This is precisely what makes Campi Flegrei so dangerous.
