A fumarole comes from gases - steam, carbon dioxide, and a little hydrogen sulfide - rushing from the earth through the vent. Its channel system reaches down into the hot rock masses, but it contains very little water. When water contacts the hot rock, it flashes into steam. Its volume increases 1,500 times and drives the gases from the vent.
The top of this volcano on the Caribbean island of Guadeloupe was wreathed in a sulphurous mist from various fumaroles. Even on a clear day, you could not always find a path between crevices when the mist was thick. A bunker-like shelter and luminous dots marking the way to it provided some measure of safety in event of worsening weather or increased volcanic activity. [Scanned from 1992 photo]
New Zealand's most active marine volcano - geothermal activity, roaring steam vents and fumaroles, bubbling mud pits, hot volcanic streams and lake of steaming acid. Vivid hues of yellow and orange from abundant sulphur

Hveragerði is a hot springs area and we were able to hike through the hills/mountains to bathe in a hot river.
A fumarole plume (right-center) rises above the steep SE slopes of Nila volcano, also known as Laworkawra or Lawarkawra. A remnant of the rim of a 5-km-wide caldera forms the forested slope at the left. The 781-m-high summit above it is a post-caldera cone that fills much of the caldera and extends to the sea at the right. Phreatic eruptions from Gunung Nila have occurred from summit vents and flank fissures during historical time.

The fumaroles and boiling streams in Mount Io is our next stop after Lake Mashu. It is an amazing experience to be in close proximity with the various volcanic features (obviously within safety limites).
The Pinnacles - These towering needle-like formations of rock, called fossil fumaroles, projecting from the Sand Creek Canyon floor, were formed under sheets of volcanic pumice that preceded Mazama's collapse. As the surface of the hot pumice cooled over the years, steam and gases were released by the hot rocks underneath through vents and tubes that were welded into cement hardness by their passage. These ancient vents now stand alone due to the erosion of the surrounding softer materials.
I noticed this effect in Rotorua, New Zealand. Wood near fumaroles and geothermal vents turns this lovely blue-black color. The crossbeams were coated with a resin that seems to have protected them.

Krýsuvík is situated on the Reykjanes peninsula in Iceland. It is in the south of Reykjanes in the middle of the fissure zone on the Mid-Atlantic Ridge which traverses Iceland. Krýsuvík consists of several geothermal fields. In this area exist a lot of solfataras, fumaroles, mud pots and hot springs.
Das geothermale Gebiet Krýsuvík liegt im Süden der Reykjanes-Halbinsel in Island in der Mitte des Spalte des Mittelatlantischen Rückens der quer durch Island führt. In diesem Gebit gibt es Schwefelquellen, Fumarolen, Schlammtöpfe und heiße Quellen.
Namafjall is a high-temperature geothermal area with fumaroles and mud pots. At a depth of 1000m, the temperature is above 200 degrees Celcius. Along with the steam comes fumarole gas, such as hydrogen sulfide which is responsible for the characteristic hot spring smell in these areas. The hot spring produce considerable sulphur deposits. In previous centuries sulphur was mined in Iceland to produce gun powder.
CAUTION: Unsafe soil and high temperatures (80-100C). Please walk only on the paths and marked trails.

La zona de Myvatn és on hem vist més fumaroles. És molt curiós veure com hi ha forats a terra on una aigua amb color de ciment bull com si estigués dintre d'una olla. La pudor a sofre és força intensa i desagradable. Els colors ataronjats són deguts al sofre que hi ha arreu, inclòs l'aire.
La foto és una panoràmica muntada amb el programa Hugin a partir de 10 fotos verticals.
Les fotos estan fetes amb una nikon d700 i un objectiu micro nikkor 60.
Myvatn area is where we have seen more fumaroles. it is curious to see how there are holes in the land with colored water like boiling cement into a pot. The sulfur stink is quite intense and unpleasant at the end. The orange color is due to the sulfur around, also in the air. The photo is a panoramic one composed from ten individual vertical photos joined with Hugin.
Photos are taken with a nikon d700 and an objective micro nikkor 60.
Recent trips to Mount St. Helens (and a thorough examination of all my photos) seems to show a new vent on the upper west crater wall. It was venting quite vociferously yesterday afternoon!
This is a reminder that Mount Saint Catherine in Grenada is a volcano! This is on one of the slopes of Mount Saint Catherine on the island of Grenada in the Caribbean Sea.
Crayfish in Fumarole Bay. There are indian stories about giant crayfish that guarded the lake in the past. The park service, however, believes that crayfish are not native to the lake. They believe the crayfish were introduced by William Steele himself, in order to attract visitors to the lake

The fumarole field at Asahidake, an area of thermal springs and gas vents where magma or hot igneous rocks at shallow depth are releasing gases or interacting with groundwater.
Asahidake, a stratovolcano, is the tallest mountain in Hokkaidō, Japan. Part of the Daisetsuzan Volcanic Group of the Ishikari Mountains, it is located in the northern part of the Daisetsuzan National Park.
