A 4.4-magnitude earthquake struck the volcanic region around Naples on Tuesday, according to Italy’s National Institute of Geophysics and Volcanology (INGV). There have been no immediate reports of damage or injuries.
The tremor hit the Campi Flegrei (Phlegraean Fields) area, located in southern Italy, at 12:07 pm local time (10:07 GMT), at a depth of three kilometres. Fifteen minutes later, another quake, registering 3.5 in magnitude, followed.
The quake was felt in Naples city centre, with residents reportedly rushing into the streets, including in nearby Pozzuoli, as per reports from ANSA news agency.
In the aftermath, two metro lines in the city were temporarily suspended, as stated by RAI News. However, no immediate reports of significant damage or injuries have emerged.
The area around Naples is prone to seismic activity due to its location in Europe’s largest active caldera, a volcanic region formed by a collapsed volcano. The caldera stretches from the outskirts of Naples and extends into the sea, covering an area of approximately 12 by 15 kilometres (7.4 by 9.3 miles).
While seismic activity is not unusual in the region, the recent quakes have raised concerns among the approximately 500,000 people living within the danger zone. A 4.4-magnitude earthquake in March 2025 caused light injuries and damage to buildings. This followed a major tremor in May 2024, which was the largest in the area for 40 years.
The most powerful volcanic eruption in the Mediterranean occurred at Campi Flegrei some 40,000 years ago. The area experienced another significant wave of seismic activity in the early 1980s, prompting a mass evacuation and leaving Pozzuoli largely deserted. However, specialists have stated that a major eruption in the near future remains unlikely.
