Naples – High levels of concern remain over the Phlegraean Fields, where bradyseism has experienced a new, worrying acceleration. The ground has begun rising at a faster rate, reaching an average rate of about 25 millimeters per month.
This data emerges from the latest weekly monitoring bulletin released by the Vesuvius Observatory of the National Institute of Geophysics and Volcanology (INGV), which highlights a clear change in pace since last October 10th.
This surge is particularly significant when compared to the previous period. From early April to early October, the uplift rate had stabilized at an average of about 15 millimeters per month. The new rate therefore marks an increase of nearly 70%, bringing the caldera's activity back to a more serious state.
The phenomenon, in its current "unrest" phase, has been ongoing continuously since November 2005. Since then, the GNSS measuring station located in Rione Terra, the heart of Pozzuoli's historic center, has recorded an impressive total uplift of approximately 155 centimeters. Of this, a full 18 centimeters have accumulated since the beginning of 2024 alone, demonstrating the intensification of events over the past year.

This ground deformation is accompanied by incessant seismic activity. In the week of November 3-9 alone, 165 earthquakes were recorded in the Phlegraean Fields, with a maximum magnitude of 2.5 recorded at 6:11 a.m. on November 9. October closed with 1.050 seismic events, the most powerful of which, with a magnitude of 3.3, occurred on October 5.
The uplift trend over the past year has been erratic. After a period of relative stability at 10 mm/month between late August 2024 and mid-February 2025, an intense seismic swarm between February 15 and 16 caused a sudden uplift of about 1 centimeter, bringing the average rate to 30 mm/month until the end of March.
After a slowdown in April, the phenomenon has now regained strength, confirming the dynamic and unpredictable nature of the Phlegraean caldera, constantly monitored by INGV experts.

It's important to be aware of these phenomena, but I don't know if we should be too concerned. Earthquakes and ground uplift are strange things, but let's hope the experts know what to do.
The article talks about bradysimus, and it worries me greatly, even though I don't know much about it. The numbers are high, and it seems like the situation is getting worse, but I'm not sure what that means for the people who live there.
It is mandatory to involve the UN and convince them that the Campi Flegrei are aliens preparing to attack the Earth with a firepower equal to 500 atomic bombs.
There will be none for anyone in the world when the Sun itself, like Enel towards its defaulters, turns off light and heat and brings darkness and cold to the entire globe.
We cannot leave a continental problem in the hands of local institutions.
This is, albeit arduous, the task of a government with the attributes: "Bringing the Campi Flegrei file to the UN" and supporting it by all possible means and methods.
