- Fumarole
A fumarole (
Latin "fumus",smoke ) is an opening inEarth 's (or any otherastronomical body 's) crust, often in the neighborhood ofvolcano es, which emitssteam andgas es such ascarbon dioxide ,sulfur dioxide ,hydrochloric acid , andhydrogen sulfide . The name solfatara, from the Italian "solfo", sulfur (via the Siciliandialect ), is given to fumaroles that emitsulfur ous gases.Fumaroles may occur along tiny cracks or long fissures, in chaotic clusters or fields, and on the surfaces of
lava flows and thick deposits ofpyroclastic flow s. A fumarole field is an area of thermal springs and gas vents wheremagma or hotigneous rock s at shallow depth are releasing gases or interacting withgroundwater . From the perspective of groundwater, fumaroles could be described as a hot spring that boils off all its water before the water reaches the surface.A good example of fumarole activity on Earth is the famous
Valley of Ten Thousand Smokes , which was formed during the 1912 eruption ofNovarupta inAlaska . Initially, there were thousands of fumaroles in the cooling ash from the eruption, but over time most of them have become extinct. Fumaroles 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. There are also an estimated four thousand fumaroles within the boundaries ofYellowstone National Park .Another example is an array of fumaroles in the Valley of Desolation in
Morne Trois Pitons National Park inDominica .
