4.7 magnitude earthquake strikes Naples near Phlegraean Fields
A 4.7 magnitude earthquake struck near Naples, Italy, at 19:46 local time on July 31, 2026. The tremor was centered in the area of the Phlegraean Fields supervolcano. Reports on the focal depth vary, with Sigma Live estimating it at 2.6 kilometers and Philenews reporting it at 4 kilometers. According to Italian media cited by Philenews, this event marks the strongest seismic activity in the region over the last 40 years.
The earthquake caused significant alarm, forcing many residents into the streets, and led to power outages across several districts of Naples. Infrastructure damage has been confirmed, specifically the collapse of a wall along a railway line and a hillside portion in the Pozzuoli area caused by a landslide. Despite the structural impact, authorities have reported no injuries to citizens as of now. The situation remains under observation as the region continues to experience volcanic and seismic instability, which has been a primary concern for local geologists and authorities in recent years.
