In short
- A shallow 4.7-magnitude earthquake near Naples injured at least 21 people, forced more than 250 from their homes and disrupted power, transport and ferry services on July 31.
At least 21 people were injured and more than 250 were evacuated after a 4.7-magnitude earthquake struck the Campi Flegrei area near Naples on Friday, July 31, 2026, according to Italian authorities cited by The Guardian.
The earthquake occurred at 7:46 p.m. local time at a depth of about three kilometres. It was the strongest tremor recorded in the southern Italian region in 40 years and was felt across Naples, on the island of Ischia and as far as the Sorrento peninsula. Two of the injured were reported in critical condition on Saturday morning.
Pozzuoli, close to the epicentre, sustained the heaviest damage. Part of a building collapsed and debris crushed parked vehicles, while inspectors declared nine buildings unsafe. A cliff collapse near the Solfatara volcanic crater also prompted warnings that further rockfalls were possible.
The quake caused power disruption affecting about 100,000 households, suspended ferry and hydrofoil services after damage made Pozzuoli pier unusable, and led to long rail delays. Many residents spent the night outside because of fears that their homes might collapse.
Italy’s National Institute of Geophysics and Volcanology said the event was part of an ongoing seismic swarm. About 60 additional tremors were recorded after the main quake, including a magnitude-3.1 event early on August 1. Campi Flegrei contains Europe’s largest volcanic crater and has experienced repeated seismic activity.
