A magnitude 4.7 earthquake struck the Campi Flegrei region west of Naples on Friday evening, injuring 21 people [1], [2].

The event is significant due to the location of the epicenter in a known volcanic area, raising concerns about seismic stability in a densely populated region.

The earthquake occurred around 7:45 p.m. local time [1]. Emergency responders said that of the 21 people injured, two sustained serious injuries [1]. The tremor originated at a depth of approximately three km [1].

Campi Flegrei is a volcanic area located to the west of Naples. The region has experienced ongoing seismic activity, which contributed to the occurrence of this latest quake [1]. Local authorities managed the immediate aftermath as residents reacted to the sudden shaking.

Reports indicate this was one of the most powerful earthquakes to hit the area in several decades [2]. The shallow depth of the epicenter often increases the intensity of shaking felt on the surface, which likely contributed to the number of casualties and the level of alarm among the local population.

Rescue teams and medical personnel were deployed to treat the injured and assess potential structural damage across the affected zone. While the magnitude was moderate, the proximity to the urban center of Naples intensified the impact of the event [1].

The occurrence of a shallow, moderate-magnitude earthquake in the Campi Flegrei volcanic complex underscores the persistent geological risks facing the Naples metropolitan area. Because the epicenter was only three km deep, the resulting surface shaking was more acute, highlighting the vulnerability of local infrastructure to seismic events in this specific volcanic zone.
