Campi Flegrei, Pozzuoli - Italy
25 Feb 2025
Here comes an article from Vulcane.net revolving the whereabouts at the unsettled Campi Flegrei (Phlegraean Fields) near Napoli, Italy - talking about the accelerated ground lift during the very recent earthquake swarms of February 2025.

Acceleration of ground uplift in the Campi Flegrei
proven during the earthquake swarm
The southern Italian caldera volcano has been doing “business as usual” over the last 3 days, meaning that it has reduced seismicity to the known level of the current uplift phase. The inhabitants of the caldera are slowly recovering from their shock and are trying to go about their lives with as much normality as possible.
Nevertheless, there are always conferences and citizens' meetings with specialists. This was also the case yesterday evening, when a discussion was held in Agnano, attended not only by residents of the westernmost Neapolitan district bordering the Campi Flegrei, but also by senior representatives of civil protection and the mayor.
Hippodrome of Agnano
The decision was taken to set up a waiting area in the Hippodrome of Agnano where worried citizens can stay during an earthquake swarm if they do not trust their houses and are afraid that they could collapse in the event of a stronger earthquake. Of course, the waiting areas are also intended for people to gather here before an evacuation.
They start to realize...
Those responsible are probably also beginning to realize that in the event of a volcanic eruption, there may not be weeks beforehand to initiate appropriate measures and that it is necessary to start creating appropriate structures. The swarm earthquake last week once again highlighted the seriousness of the situation.
As published today in the weekly bulletin of the INGV
for the observation period February 17 to 23, a balance sheet was once again drawn up, which makes it clear that the swarm earthquake was an event of superlatives: 692 tremors were recorded between February 15 and 19. 610 quakes had a magnitude greater than zero.
Right at the beginning of the swarm, the ground uplift accelerated significantly and in the first two days 10 mm were added; as much as the ground usually rises in a month. This makes it obvious that the ground uplift was the trigger for the earthquake swarm. If you look at the unadjusted measured values, you can see that the ground initially lifted by up to 25 mm, but then the ground uplift dropped back at the end of the phase. I do not know whether these were actual soil movements or whether it was a metrological effect.
The researchers could not detect any change in the gas output, which actually surprises me, especially if you believe the theory that the ground uplift was caused by fluids, i.e. gas and aqueous solutions, which penetrated the hydrothermal system.
The gas temperature of the Pisciarelli fumarole was 97 degrees and thus above the condensation point of 95 degrees.
Little understood and very complex
If you read the statements of various researchers on the processes in the Campi Flegrei in the local press, you realize how little the processes of the alleged bradyseism are understood and how complex they can be. What I find astonishing is the repeatedly emphasized statement that for centuries there has been an eternal up and down of the ground, which has always been accompanied by periods of increased seismic activity. According to geophysicist Giuseppe De Natale, however, the phases known as bradyseismos only occurred a few decades before and after the last two eruptions. In the same way, people always refer to the fact that before the Monte Nuovo eruption [from Sept 29 - Oct 6, 1538], the ground is said to have risen by up to 17 meters within a few months before the eruption occurred.
Although it is all very well to recognize certain patterns in the processes of nature, no one says that they must always repeat themselves in exactly the same way. You don't have to look far in Pozzuoli to see that, because a glance at Mount Etna shows that pattern recognition can be smoke and mirrors.
