Caution, Naples! Signs of a dangerous volcanic eruption increase

In the Phlegräische fields west of Naples, Italy, volcanologists register a worrying increase in volcanic activity. The super volcano, which is located in a region with over 500,000 inhabitants, is under particularly intensive observation. This development is underpinned by the geopolitical events of recent years as well as by recent scientific studies.

The region received special attention after an earthquake on May 13, 2024 with a strength of 4.4, the epicenter of which was in the Phlegräische fields. The city of Pozzuoli was particularly affected, where cracks were found in some buildings. Fortunately, there were no reports on injuries. Such earthquakes are not new; Similar strong vibrations were registered on Whit Monday 2024 and in mid -March 2025. The alarming activity caused the alarm level in the region to be stable on yellow for eleven years, and the authorities take new measures to improve the earthquake security of the buildings.

scientific knowledge and dangers

A current study, conducted by researchers from the University College London and the Italian Istituto Nazionale di Geofisica e Vulcanologia, indicates an increased probability of a volcanic eruption. This investigation has shown that the rock ceiling above the magma chamber is weakened more than previously assumed. The pressure under the Campi Flegrei has been increasing since 2005; The soil has increased over one meter in Pozzuoli since autumn 2005 and continues to arch with a rate of about 1.5 cm per month. Historical outbreaks in the region are not uncommon, the last one occurred in 1538 and led to the formation of Monte Nuovo.

A central topic of discussion is the different interpretations of this data. Giuseppe de Natale, head of research on the INGV, expressed critical views on the study and believes that the rock above the Magmakammer could be more resistant than in the conclusions of the study. Nevertheless, the general trends - from an increase in earthquake activities to ground survey - are worrying.

evacuation plans and security measures

Due to the potential risk of an outbreak, the authorities work on plans for possible evacuations. In an emergency, the people living in the red zone would have to be evacuated within 72 hours. In addition, there are already existing emergency instructions: instructions from the authorities should be followed, and blocking districts should be strictly avoided. The travel warning of the Federal Foreign Office is currently missing and air traffic is normal, but it is recommended to pursue the current situation on the website of Italian civil protection.

Development in the Phlegraian fields remains tense and experts advise caution. A larger outbreak could not only have local, but also global consequences, as a historical outbreak showed 39,000 years ago that influenced the climate worldwide. In view of the rising risks, it is essential to continue to observe the situation closely and to react appropriately.
