The only one of Pozzuoli's three volcanoes still active dates back to 1198. The Solfatara volcano has a height of 458 metres and resulted from a phreatic eruption. That means magma came into contact with groundwater, emitting steam and pulverised rock. In Roman antiquity, this volcano was known as Forum Vulcani and was considered a beneficial spring. The volcano still has limited activity but still has many solfatars, a type of fumaroles named after the volcano. Solfatara is located in a volcanic area Campi Flegrei in Italy caused by Alpine orogeny, in which the African plate collides with the Eurasian plate. Solfatara is one of the most active parts of this super volcano. Since 2017, the Solfatara crater has been closed to the public due to a serious visitor incident. The adjacent campsite has since turned into a ruin. Solfatara is one of the works of a larger project on Campi Flegrei, the super volcano west of Naples, which I have been working on regularly since 2023. (HW)
