Campi Flegrei, a new 3.8-magnitude tremor after the record-breaking earthquake: collapses, eight injuries, and a night of terror.

The earth continues to shake in the Phlegraean Fields. After the powerful magnitude 4.7 earthquake recorded at 7:49 PM, a new magnitude 3.8 tremor struck the Phlegraean Fields at 10 PM, fueling fear among the population already shaken by the first earthquake.

According to the operations room of the Vesuvius Observatory of the INGV, the epicenter was located in the Gulf of Pozzuoli, at a depth of approximately three kilometers. The earthquake was clearly felt not only in the municipalities of the Phlegraean Fields area, but also in numerous neighborhoods of the city of Naples.

Eight injured and collapses: the emergency toll

The provisional toll for the evening is eight people injured, some of whom suffered fractures. All the injured were in the Pozzuoli area, the municipality closest to the epicenter of the main quake.

The earthquake's aftermath is evident in various areas of the city: collapsing cornices and walls, falling debris, homes with deep cracks, especially in older buildings, and furniture overturned inside. Many families, fearing further tremors, have chosen to spend the night outdoors.

One building has been declared uninhabitable, while technical checks continue on the other affected properties.

The collapse at Girolamini is impressive

Among the images making the rounds on social media are those of a cliff collapse in the Girolamini area of ​​Pozzuoli.

Videos show huge boulders breaking off from the rock face and crashing onto the roadway. Some shatter on impact, others crashing into parked cars, crushing them. The entire area is engulfed in a thick cloud of white dust, while dozens of people flee in panic.

It is precisely in this area that some of the injuries were recorded, fortunately all classified as yellow code.

Seismic swarm still ongoing

Seismic activity did not stop with the main quake. After the magnitude 4.7 shock, the INGV recorded at least thirteen seismic events with a magnitude greater than 1, in addition to the subsequent magnitude 3.8 shock.

The swarm is still ongoing and experts continue to monitor the evolution of the phenomenon, while further aftershocks are being felt by the population.

Cumana railway halt and infrastructure checks

Among the consequences of the earthquake was the interruption of the railway service on the Cumana line.

Traffic was suspended both to allow for technical inspections of the network and due to the collapse of a wall adjacent to the tracks. Authorities are carrying out safety checks on infrastructure and public buildings.

The mayor's appeal: "Keep calm."

The mayor of Pozzuoli, Luigi Manzoni, urged residents to remain calm, reassuring them that the rescue operations were fully operational.

"We immediately activated the Municipal Operations Center to coordinate all monitoring and assistance activities for the population. We are in constant contact with the Vesuvius Observatory, the Civil Protection Department, and all the relevant authorities to monitor the evolution of the seismic swarm minute by minute," the mayor wrote on his social media channels.

The strongest earthquake in the last forty years

The magnitude 4.7 earthquake represents a new record in the recent history of bradyseism in the Phlegraean Fields. It is, in fact, the strongest shock recorded since the beginning of the new phase of bradyseismic crisis and the strongest felt in Campania since the 1980s.

The previous record was held by two magnitude 4.6 earthquakes recorded on March 13 and June 30, 2025, which to date were the most powerful seismic events of modern times in the Phlegraean Fields area. This evening's shock surpasses that value and marks a new landmark in the long crisis affecting the Campi Flegrei supervolcano.
