A 4.4 magnitude earthquake struck Italy’s Campi Flegrei super volcano Monday evening, causing mild damage in the town of Pozzuoli, the epicenter, and as far away as the city of Naples, some 20 kilometers (12 miles) away, according to Italy’s National Institute of Geophysics and Volcanology (INGV).
Cracks in walls and falling cornices were reported, Italy’s Fire Brigade spokesman confirmed to CNN.
The 4.4 earthquake at a depth of 3 kilometers is the strongest earthquake to hit the highly seismic area in the past 40 years, according to INGV data. The quake is part of an ongoing “seismic storm” that has seen more than a dozen events over 2.0 magnitude in the past 48 hours.
The 4.4 tremblor at 8:10 p.m. local time was preceded by a 3.5 earthquake an hour earlier.
