1168 PHLEGRAEAN FIELDS: Pozzuoli rises again, the port is disappearing
6 Mar 2026 The Campi Flegrei caldera, a complex volcanic system in Europe, is experiencing ongoing changes. Ground uplift, degassing from fumaroles, and seismic activity are all indicators of the system’s dynamic nature. The ongoing monitoring of these phenomena is crucial for understanding the caldera’s behaviour and potential risks.
Key points
* Pisciarelli Fumarole Activity: The Pisciarelli fumarole exhibits high pressure with strong jets of hot mud, indicating ongoing hydrothermal fluid circulation and compression. * Caldera Monitoring Update: Despite a slight decrease in visible gas emissions, the Campi Flegrei caldera remains active and constantly evolving. * Volcanic Activity Monitoring: Continuous ground tremors, seismic swarms, and earthquakes indicate an active volcanic system. * Fumarole Temperature Measurement: Pisciarelli fumarole temperature recorded at 105.1°C, showing small variations can indicate changes in deep fluid flow. * Solfatara Crater Observations: Reduced degassing and steam plume intensity observed in Solfatara crater, but variations may not necessarily indicate decreased activity. * Land Uplift Evidence: Visible marks on rocks and the emergence of the seabed demonstrate significant land rise. * Port Morphology Change: The rising seabed is altering the port’s morphology, making areas unusable and affecting navigability. * Bradysmosis Indicator: The drying up of areas in the Flavian Amphitheater serves as a clear sign of ongoing ground uplift.
