La ville italienne qui s’élève au-dessus d’un supervolcan

In Italy, the ground beneath an entire city is rising month by month — and the supervolcano that lies dormant below continues to build pressure. Beneath the Italian town of Pozzuoli, near Naples, the ground is rising. Not symbolically. Physically. Month after month, the surface above one of Europe’s most dangerous volcanic systems is heaving as pressure continues to build beneath the Phlegraean Fields — a vast volcanic caldera larger, more complex, and less predictable than the infamous Mount Vesuvius. In this Science of Survival documentary, we explore the unsettling reality of Campi Flegrei, the Italian supervolcano that scientists are monitoring in real time. In recent years, the region has seen an increase in seismic swarms, more powerful earthquakes, gas emissions, ground deformation, and growing concern about what lies beneath the surface. In Pozzuoli, residents have felt the earth shift. Buildings have cracked. Families have been awakened by tremors. And beneath their feet, the Earth continues to shift. Campi Flegrei is not a classic cone-shaped volcano. It is a caldera: a vast collapsed volcanic system, composed of faults, fractures, underground reservoirs, hydrothermal fluids, and pressure zones. Unlike the more recognizable Mount Vesuvius, the Phlegraean Fields extend beneath cities, roads, ports, and densely populated neighborhoods near Naples. Millions of people live within the expanded risk zone. But perhaps the most worrying thing is not what we see. It is what we cannot see. Scientists can measure the uplift of the ground using satellites and GPS. They can detect shallow earthquakes beneath the caldera. They can analyze the volcanic gases escaping from its depths. They can model pressure, fluids, fractures, and possible eruption scenarios. But one crucial question remains: will this activity eventually subside, as it has in the past, or is Campi Flegrei approaching a critical state? This documentary examines bradyseism, seismic swarms, ring faults, hydrothermal pressure, magmatic systems, and the fragile boundary between scientific monitoring and impossible prediction.
