Phlegraean Fields

The Phlegraean Fields, or Campi Flegrei, are a large volcanic area near Naples, Italy, characterized by a series of craters, calderas, and geothermal activity. It’s essentially a supervolcano with a history of massive eruptions that have shaped the landscape. The area is known for its hot springs, fumaroles, and seismic activity. Because of its potential to erupt again, it is closely monitored. The volcanic activity here results from magma beneath the surface, making it a significant geological and cultural site with ancient ruins and vibrant geothermal features.
