A 4.4 magnitude earthquake just 3 km deep struck near Pozzuoli on May 13, alarming over 2 million people in a high-risk volcanic area
A shallow earthquake in a sensitive area
A magnitude 4.4 earthquake hit the Campi Flegrei volcanic area at 12:07 PM (local time) on Tuesday, May 13, 2025. The shock was recorded at only 3 km depth, making it a shallow and widely felt event.
The epicenter was near Pozzuoli, a densely populated area west of Naples. The quake was recorded by the INGV – Osservatorio Vesuviano at coordinates 40.8245 N, 14.1117 E.
Over 2 million people potentially affected
The quake was felt strongly across the Phlegraean Fields, including Naples and many surrounding towns such as Quarto, Bacoli, Marano, Giugliano, Casoria and more. In total, more than 2 million residents live within 20 km of the epicenter.
Given the volcanic nature of the region, residents reacted with fear, though no major damages or injuries were reported at this time.
Part of an ongoing seismic swarm
This is not an isolated event. The Campi Flegrei region has been experiencing ongoing seismic swarms, likely tied to underground pressure and ground uplift.
Experts from INGV suggest that this quake fits the pattern of fractures due to uplift, which is common in volcanic calderas under stress.
What to do in case of more shocks?
Civil protection officials are urging caution and reminding residents to follow standard earthquake safety procedures:
- Stay away from glass and suspended objects
- Take cover under a sturdy table or doorway
- Avoid elevators and staircases
- Keep an emergency bag ready with essentials
A signal not to ignore
This earthquake is a wake-up call for an area where volcanic and seismic risks intersect. Continued investment in monitoring, infrastructure, and public preparedness is essential.
