Soffioni
Soffioni (Italian: [sofˈfjoːni]; sometimes spelt suffioni), a name applied in Italy to certain volcanic vents which emit jets of steam, generally associated with hydrogen sulfide and carbon dioxide, sometimes also with a little ammonia and marsh gas.[1]
The soffioni are usually arranged in groups, and are best represented in the Maremma of Tuscany, where they contain a small proportion of boric acid, for which they are utilized industrially.[2][1] For such natural steam-holes, the French geologists often use the term soufflards in place of the Italian soffioni.[1]
