Volcanic Risk Profile

Naples is one of the most densely populated volcanic zones on Earth — over 600,000 people live inside the Vesuvius "red zone" (high-risk evacuation area). Vesuvius has not erupted since 1944 and is considered overdue, making the metro region one of the most studied — and feared — volcanic risk profiles globally.
