Italy is bracing for an unprecedented crisis as the Campi Flegrei supervolcano near Naples continues to exhibit alarming seismic activity. The Italian government, in a move underscoring the gravity of the situation, is planning a potential mass evacuation of the tens of thousands residing in the vicinity of this geological giant. This supervolcano, which overshadows the infamous Vesuvius, has experienced over 1,100 earthquakes in just one month, including tremors reaching magnitudes of 4.0 and 4.2 – the strongest in the region for forty years.

The Campi Flegrei, also known as the Phlegraean Fields, is not just a single volcanic entity but a sprawling caldera with 24 craters. It is situated to the west of Naples and encompasses densely populated towns and villages such as Pozzuoli, Agnano, and Bacoli, with a combined population exceeding half a million. The scale of this supervolcano is monumental, dwarfing Vesuvius, which is etched in history for the destruction of Pompeii in AD79.

Scientists attribute the surge in seismic activity to bradyseism, a phenomenon where the earth’s surface rises or falls due to changes in underground magma chambers. Although most volcanologists do not see an imminent eruption threat, the ground’s steady rise of 1.5cm per month raises significant concerns about the structural integrity of local buildings and infrastructure.

The Italian government’s contingency plans involve comprehensive assessments of building resilience in the quake-hit areas. These measures, set for discussion at a cabinet meeting, are a testament to the seriousness with which the authorities are approaching this potential natural catastrophe. Moreover, the civil protection minister, Nello Musumeci, has indicated that evacuations would be a measure of “extreme necessity”.

Beyond structural evaluations, the cabinet is poised to allocate additional resources to local civil protection agencies. These agencies are the frontline defense in emergency response and will play a crucial role in managing any crisis that may arise. Additionally, a public awareness campaign is on the anvil, aimed at preparing the populace for potential emergencies.

The medical infrastructure in the region is not left out of these preparations. Local hospitals are set to commence evacuation drills, a prudent step to ensure readiness in the face of possible stronger earthquakes or volcanic eruptions. This level of preparedness is reminiscent of the 1980s when Campi Flegrei experienced a similar flurry of seismic activity, leading to the temporary evacuation of 40,000 people from Pozzuoli.

The history of Campi Flegrei is both fascinating and ominous. Its last significant eruption occurred in 1538, but it is the colossal eruption that happened 39,000 years ago, potentially leading to the extinction of Neanderthals, that captures the imagination and stirs fears. The reach of that eruption was so vast that traces of its magma have been discovered as far away as Greenland, over 2,800 miles (4,500km) distant.

As Italy grapples with this looming geological threat, the situation at Campi Flegrei serves as a stark reminder of the immense power of nature. The ongoing seismic activity is not just a local concern but a matter of global interest, given the potential implications of an eruption of this scale. The focus now is on rigorous monitoring, public education, and emergency preparedness, with the hope that these efforts will mitigate the impact of any geological eventuality.

The Italian government’s response to the seismic unrest at Campi Flegrei is a model of proactive disaster management. The comprehensive measures being put in place reflect a deep understanding of the risks posed by this supervolcano. As the world watches, the residents of the towns and villages nestled around Campi Flegrei live with the uncertainty of what the next tremor might bring, hoping for stability but preparing for the worst.
