The Solfatara maar-diatreme in the Campi Flegrei caldera was formed during an explosive eruption about 3,850 years ago. The crater is still thermally active, releasing gas that includes H2O, CO2, and CO. A small phreatic eruption occurred at Solfatara in 1198 CE. Photo by Roberto Scandone, 1984 (University of Rome).
