Strong 4.7-Magnitude Quake Shakes Naples’ Campi Flegrei Area

Core Event
On July 31, 2026 at 19:46 GMT a magnitude 4.7 earthquake struck the Campi Flegrei volcanic area west of Naples. INGV recorded the tremor at a depth of about 3 km and located the epicentre roughly 6 km from the city centre. The shock caused power outages, halted regional rail and metro services, and produced minor structural damage, including a collapsed façade in Pozzuoli and fallen cornices in nearby districts.
Background & Context
Campi Flegrei is Europe’s largest active supervolcano, characterised by a shallow magma chamber that drives frequent low-magnitude seismicity and ground-level changes known as bradyseism. The region last experienced a comparable tremor in the early 1980s, when a seismic crisis forced evacuations. Prior to the July 2026 event, the most significant recent quakes were magnitude 4.6 shocks on March 12 and June 30, 2025.
Data & Statistics
- Magnitude: 4.7 (INGV)
- Depth: ~3 km (INGV)
- Epicentre: Campi Flegrei, ~6 km west of Naples
- Injuries reported: conflicting figures (8, 10, or unspecified)
- Power outages: neighbourhoods including Fuorigrotta, Bagnoli, Soccavo, Pianura, Vomero, Chiaia, Colli Aminei, Pizzofalcone, Bedroom, Mugnano, Giugliano
- Transport impact: suspension of regional rail (Cumana and Circumflegrea lines) and metro Line 1 for safety checks
- Structural damage: collapsed façade in Pozzuoli; cornice and plaster falls in Pozzuoli and Bagnoli; no major building collapses reported
Official Statements & Responses
- Nello Musumeci, Minister for Civil Protection, said he was in constant contact with the prefect of Naples and the head of the National Department of Civil Protection, that a Crisis Unit had been convened, and that coordination among operational structures was being guaranteed.
- Luigi Muro, Mayor of Naples, activated the municipal Civil Protection Operations Centre (COC) immediately after the quake.
- The Italian government confirmed that Prime Minister Giorgia Meloni was in regular contact with Musumeci and the government delegate for Naples, Michele di Bari, to monitor the situation.
- The Italian fire service reported minor building damage and numerous calls for assistance with stuck elevators, but no immediate rescue requests.
On-the-Ground Reports
Residents fled streets as dust filled the air, especially in the historic districts of Pozzuoli, Ischia and Procida. Video footage showed collapsed façades and fallen boulders crushing parked cars. Emergency crews responded to dozens of calls about elevators and minor structural failures, while power companies worked to restore electricity across the affected neighbourhoods.
Conflicting Reports & Gaps
- Injury figures vary: The Sun cites eight injured, Voxnews reports ten, while Manchester Evening News mentions “a number of people” without a count. No official casualty tally has been released.
- Damage assessments differ: Bluewin and Il Sole 24 Ore note only minor damage, whereas The Sun describes “numerous damages” and collapsed façades. Comprehensive structural surveys are still pending.
What’s Next
The Crisis Unit remains active, and INGV has pledged continuous seismic monitoring of the Campi Flegrei area. Authorities plan to complete safety inspections of rail and metro infrastructure before resuming service, and electricity providers aim to restore full power in the affected neighbourhoods within the coming days.
