A magnitude 4.7 earthquake struck the Campi Flegrei volcanic area near Naples, injuring 21 people, forcing hundreds from their homes and setting off an extensive emergency response.
The earthquake hit at 7:46 p.m. local time on Friday at a depth of 2.6 kilometers, with its epicenter in the Phlegraean Fields and tremors felt across several Naples neighborhoods.
Italian Civil Protection Minister Nello Musumeci said the seismic swarm, a sequence of earthquakes occurring close together, was continuing and could bring further tremors above magnitude 3.
Firefighters brought in additional teams to inspect buildings across Campi Flegrei, focusing on structural damage and possible risks to residents.
Authorities declared eight buildings and five businesses uninhabitable, leading to the evacuation of around 290 people from 130 families.
In Pozzuoli, a city within the volcanic area, 250 people were displaced after officials declared three streets unsafe because of concerns over damaged structures.
Inspections in Pozzuoli identified nine unsafe buildings, while authorities warned that more residents could be affected as technical checks move forward.
Although 21 people were injured, Musumeci said five remained in hospital receiving treatment for trauma and bone fractures.
The tremor caused power outages from Pizzo Falcone to Fuorigrotta, while firefighters responded to reports of falling debris, damaged buildings and people trapped inside elevators.
Campania Region President Roberto Fico said, “There's great dialogue and collaboration, and we're moving forward for the protection and safety of our population,” as Pozzuoli activated its Municipal Operations Center to oversee monitoring and assistance.
