Magnitude 4.7 Earthquake near Naples: Phlegraean Fields Tremble

The region's operations center coordinated checks of public buildings, schools, and hospitals, according to its own statements. Spokeswoman Lucia Pappalardo said that precautionary inspection rounds had been launched and that they were in close contact with the municipalities.

Scientists describe the Phlegraean Fields as a so-called supervolcano. A spokeswoman for the Observatory explained: "Supervulkane zeichnen sich durch eine besonders grosse Magmakammer und enorme Gewalt aus: Anders als normale Vulkane explodieren Supervulkane regelrecht." This geological classification was also the subject of reporting on Thursday.

Italy lies in a seismically active zone where the African and Eurasian plates meet. Earthquakes are part of everyday life there, which is why authorities have well-established warning and response chains. According to those responsible, the current quake was also handled in accordance with applicable protocols.

What are the Phlegraean Fields?

Many residents of Naples left their homes after the earthquake and stayed outdoors. On social networks, residents reported shaking furniture and falling objects, but no major damage was apparent from the initial reports.

The Phlegraean Fields have been under special observation for years because the ground in parts of the area rises and falls, a phenomenon known as bradyseism. Experts see this as a sign of the dynamics of the underground magma system.

According to the news agency APA, the operations center increased its presence in the coming hours to prepare for possible aftershocks. The authorities also announced that they would keep the situation under review and take further measures if necessary.

Reaction of authorities and official bodies

The Vesuvius Observatory continuously evaluated the seismic data and intended to publish further information during the night. The city of Naples set up a hotline for concerned citizens.

Experts emphasized that a single earthquake of this magnitude does not allow any immediate conclusions to be drawn about an imminent eruption. At the same time, they pointed out that the long-term monitoring of the Phlegraean Fields remains an unchanged high priority.

Reporting on the earthquake continued in the Italian and international media late into the evening. The authorities asked the public to refer only to official sources and to ignore rumors on social media.

As of the editorial deadline, there were no reports of collapsed buildings or injuries. According to the operations center, the situation would continue to be monitored, and further aftershocks could not be ruled out.
