    • ‘Surface geothermal manifestations include hot steaming ground, fumaroles, mud pools, and warm to boiling hot springs.’
    • ‘Orpiment is most frequently encountered in epithermal (near-surface, low - temperature) hydrothermal settings such as veins, hot springs, fumaroles.’
    • ‘Other solfataras and fumaroles have produced a plethora of sulfates, and it is plausible that additional sulfates occur at El Desierto.’
    • ‘Realgar is most frequently encountered in epithermal (near-surface, low-temperature) hydrothermal settings such as shallow veins, hot springs, and fumaroles.’
    • ‘As Tharanal had led them towards it yesterday, he'd seen thick plumes of smoke - and other, more noxious vapors - rising from outlying ventilation shafts like the fumaroles of volcanos.’
    • ‘Other evidence of increased activity are the formation of a new line of fumaroles at Nymph Lake, just north of Norris, and marked through temporary increases in ground temperatures in Norris' Back Basin.’
    • ‘It is found with realgar in gypsum at the Boccheggiano and Niccioletta mines and the Tognetti quarry, Seravezza, Tuscany, as well as in the fumaroles of Vesuvius and Campi Flegrei, Italy.’
    • ‘It was preserved because of its amazing hot springs, fumaroles and geysers.’
    • ‘This includes what we call volcanoes, as well as geysers and fumaroles.’
    • ‘Well, it's the largest grouping of magmatic features on Earth: huge geysers (Old Faithful can reach 190 feet), hot springs, steaming fumaroles, and mud pots - the sad remains of geysers that have lost their oomph.’
    • ‘Americans Mike Conway and Andy Macfarlane and Ecuadoran geochemist Luis LeMarie were going to insert temperature probes, known as thermocouples, into the fumaroles.’
    • ‘But while the ancient imagination doubtless conjured up giants in plumes of gas from fumaroles (vents from which volcanic gas escapes into the atmosphere), the earthquakes that Pliny described so casually were more than just portents.’
    • ‘In Chile's Atacama Desert, you'll ascend to 14,800 feet in the Andes to walk among spouting geysers and fumaroles, see cool salt formations in the Valley of the Moon, and visit a pink flamingo colony on Chaxa Lagoon.’
    • ‘Walk the boardwalk by Old Faithful for both wildlife viewing and a fascinating view of hot springs, mud pots, fumaroles, and geysers.’
    • ‘Surprisingly, Saunders suggests a start at the fumarole on the side of Chihsing Shan (Seven Star Mountain).’

    • ‘He survived only by lying next to a thermal fumarole, scalding one side of himself while freezing the other.’
    • ‘Less cold-tolerant organisms may have held out in locations where geothermal action preserved warm micro-climates - some perhaps from around deep-sea fumaroles, though photoautotrophs must clearly have ‘over-wintered’ elsewhere.’


Early 19th century from obsolete Italian fumaruolo, from late Latin fumariolum ‘vent, hole for smoke’, a diminutive based on Latin fumus ‘smoke’.
