Escalating soil CO2 degassing correlates with ground uplift and seismicity during the ongoing unrest of Campi Flegrei (2005–2025)

The mechanism driving accelerating unrest at the densely populated Campi Flegrei caldera since 2005 remains debated. Analyzing an unprecedented two-decade geochemical dataset, we show that escalating soil CO2 fluxes closely tracks caldera uplift, revealing magmatic fluid pressurization at 3- to 4-kilometer depth and he...
