Campi Flegrei, Campania, Italy. Solfatara volcano. The bubbing mud pit is made up by rainwater and vapor condensation, which mix with the clay type material present on the surface of the Volcano crater. The gas composition which spews out from the mud pit is varying (H2S, N2O, H2O, CH4, He). The temperature is about 170°.

Solfatara volcano, 1 km from Pozzuoli, is a part of Campi Flegrei, a nested caldera resulting from two large collapses related to past eruptions. At present, fumaroles and thermal springs occur in different sectors of the Campi Flegrei caldera. In particular, fumarolic activity occurs along the coast south of Pozzuoli and concentrates in the Solfatara area. Around 3 million people live in the Naples hinterland, that is why the Campi Flegrei is studied and monitored, being one of the most dangerous volcanic areas in the world.
