A small volcanic vent from which gases and vapors are emitted.
A vent which releases volcanic gases. These include steam (H2O), carbon dioxide (CO2), sulfur dioxide (SO2), hydrogen sulfide (H2S), as well as other volatile gases emitted from subterranean magmas.
Fumaroles are vents from which volcanic gas escapes into the atmosphere. Fumaroles may occur along tiny cracks or long fissures, in chaotic clusters or fields, and on the surfaces of lava flows and thick deposits of pyroclastic flows. They may persist for decades or centuries if they are above a persistent heat source or disappear within weeks to months if they occur atop a fresh volcanic deposit that quickly cools.
