Pozzuoli's Ancient Craters And A Legacy Of Volcanic Unrest

POZZUOLI, ITALY - OCTOBER 23: The general view of the fumaroles in the Solfatara area of Campi Flegrei on October 23, 2023 in Pozzuoli, Italy. The Campi Flegrei, a large dormant volcano near Naples, has a history of eruptions, with the last one in 1538. Recently, increased seismic activity and rising land levels have raised concerns among local residents. Experts from the National Institute of Geology and Volcanology (INGV) say these are typical signs of the volcano being active, but they're keeping a close watch because this area has a history of big eruptions.
