Campi Flegrei
Caldera · 458 m · Italy
Campi Flegrei sits on the Eurasian Plate, in a subduction zone. 20 eruptions are known since the end of the last ice age, the most recent in 1538. Its major eruptions caused at least 30 deaths.
Campi Flegrei is a vast, largely inhabited caldera west of Naples. About 39,000 years ago the Campanian Ignimbrite eruption was one of the strongest in Europe in the last 200,000 years.
The ground here slowly rises and falls, a process called bradyseism that is clearly visible in Pozzuoli. The last eruption, in 1538, built Monte Nuovo. Since the mid-2000s the ground has been rising again and earthquakes have become more frequent.
