1453 Phlegraean Fields: Pozzuoli shocked, sea retreats and ground keeps rising!
EN English (FR IT PT SP)
21 Mar 2026
The Phlegraean Fields continue to show signs of activity despite a decrease in visible degassing. The ground uplift is causing significant changes, including the drying of mud pools and the receding sea at Pozzuoli port, making it difficult for boats to dock. The ongoing monitoring project, including the installation of a seismograph, aims to better understand these changes and their potential impact.
Key Points
- Monitoring Importance: The quietest phases in the Phlegraean Fields can conceal profound dynamics and changes that are invisible to the naked eye but can evolve rapidly.
- Seismograph Fundraiser: A seismograph is planned to be installed to intercept microtremors in real time and understand what’s happening underground. A Gofundme fundraiser is available for support.
- Monitoring Date: The monitoring report is for Saturday, March 21, 2026, starting with Fumarola Pisciarelli.
- Misleading Degassing: General degassing seems reduced, but pressure remains high with violent mud jets.
- Stable High Temperature: Pisciarelli Fumarola temperature remains high at 104.8°C, indicating continued system activity.
- Drying Mud Pools: Mud pools, especially the central one in Solfatara crater, are almost completely dry.
- Ground Uplift Impact: The rising ground in Pozzuoli is transforming the port area, making the seabed shallower and hindering boat docking.
- Fumarole Temperature: The Bocca Grande Fumarole recorded a consistently high temperature of 186°C, indicating significant changes in the volcanic system.
- Port Transformation: The Darsena, once a port basin, now resembles land due to the uplifting ground, forcing fishermen to relocate and impacting ferry operations.
- Ground Rising Indication: Dryness of the ground signifies that it is rising.
- Continuous Monitoring: Daily observation using drones, with updates shared on the channel.
