An earthquake measuring Md 3.5 was recorded by the Monitoring Network of the Vesuvius Observatory of the National Institute of Geophysics and Volcanology (INGV) at 15:14 (local time) on 16 March 2022. The epicenter was located in the Solfatara area, in Campi Flegrei (North-West of the city of Naples) at a depth of about 2,7 km. The event is part of a swarm that began at 15.12 (local time) and consisted of more than 16 earthquakes. Francesca Bianco, Director of the Vesuvius Observatory of INGV, highlighted: “The volcanic activity of Campi Flegrei is constantly monitored by the monitoring networks of the Vesuvius Observatory, in close contact with the Civil Protection Department. The geophysical and geochemical parameters analyzed indicate the persistence of the trends recorded in the previous months. At present there are no elements such as to suggest significant evolutions of the system in the short term, it being understood that a possible future variation of the monitored parameters (seismological, geochemical and soil deformations) may lead to a different evolution of the hazard scenarios".
