Italy’s Campi Flegrei is “speeding toward a breaking point” — and 500,000 people near Naples could be at risk
A new scientific study published in May 2026 concludes that Campi Flegrei — the volcanic superaldera west of Naples, Italy — is accelerating toward a critical “breaking point” within the next decade. The caldera is home to 500,000 people and sits adjacent to the 3-million-person Naples metropolitan area. Researchers warn the transition could produce a major eruption — or a less destructive but still severe volcanic event. Italy’s alert level remains Yellow.
