It was totally downpouring so we broke out the rain gear and spent a couple hours at Norris Geyser Basin, most of it completely by ourselves. Very rare for this part of the park and we made the most of it.
White Island (Whakāri), 48km offshore from NZ, is the northernmost active volcano in the Taupo Volcanic Zone - a 250km-long zone of intense volcanism that marks the boundary of the Australian and Pacific tectonic plates.
The island has been built up by continuous volcanic activity over the past 150,000 years. About 70 percent of the volcano is under the sea, making this massive volcanic structure the largest in New Zealand. The 321-m-high island consists of two overlapping andesitic-to-dacitic stratovolcanoes.
Intermittent moderate phreatomagmatic and strombolian eruptions have occurred at White Island throughout the short historical period beginning in 1826, but its activity also forms a prominent part of Maori legends. Formation of many new vents during the 19th and 20th centuries has produced rapid changes in crater floor topography.
A sulphur mining venture began on the island in 1885; this was stopped abruptly in 1914 when part of the crater wall collapsed and a landslide destroyed the sulphur mine and miners' village; twelve lives were lost.
The most recent eruption occured in 2000. A new vent developed and began to emit ash. An eruption occurred late in July which covered the crater area in scoria, also displacing the main crater lake and forming a new explosion crater 150 m across.
Fumarole at Hverir near Lake Myvatn
Apart from being awesome to look at, they also make amazing amounts of noise!
One of the fumaroles at Hveravellir, in the middle of the Kjölur route through the Icelandic highlands.
Hverir in North Iceland. Geothermal location with bubbling mud pools and steaming fumaroles that emit sulfur-rich gas.
Small fumarole/solfatara vent on north side of Teide Volcano.
Did not noticed any active volcanism whilst I was visiting there, but careful examination of 2 of my live HDR photos just after I came back home, revealed a fumarole; a small solfatara on the right rim of the summit, producing a small puff of steam, plus CO2 & Sulfurous fumes.
There is still an active magma chamber underneath the mountain.
The summit last erupted about 850 AD. The last eruption on Teide volcano was on El Chinyero vent in 1909. Other significant eruptions occurred in 1704-1706 & 1798.
One of the most active volcanoes in Southern Kamchatka. It is formed from four (predominantly basaltic) coalescing stratovolcanoes. The crater contains a powerful geothermal field with numerous fumaroles, boiling mud pools/springs. Care is required when visiting this site (should keep away from the direction of the toxic fumes emanating from the fumaroles and any unstable areas).
Krýsuvík is a geothermal area on the Reykjanes Peninsula known for its steaming vents, bubbling mud pots, colorful mineral deposits, and volcanic landscapes. The region lies within an active volcanic system and showcases the powerful geothermal forces that shape Iceland. Krýsuvík is one of the most accessible geothermal sites in the country and a popular destination for visitors exploring the unique geology of the Reykjanes peninsula.
Seltún
Seltún is the main geothermal area of Krýsuvík on the Reykjanes Peninsula in southwest Iceland. The site is known for its steaming fumaroles, bubbling mud pools, sulfur deposits, and brightly colored mineral-rich hillsides. Boardwalks allow visitors to explore the active geothermal landscape safely while observing the volcanic forces that continue to shape the region.
An Vulkanen und in ihrer Nähe kommen Fumarolen vor, die mit ihren Gasen neben Schwefelwasserstoff auch gasförmigen, elementaren Schwefel ausstoßen, der beim Abkühlen an der Austrittsstelle kondensiert und Kristalle bildet (wikipedia).
Steam, carbon dioxide and sulphurous volcanic gases belching from several fumaroles on Vulcano, Aeolian Islands, Italy. The smell is pretty unpleasant and rather toxic, owing to the presence of large concentrations of hydrogen sulphide ('bad egg gas'). Digitised this one via a slide copier and DSLR from 35mm Kodak Ektachrome E100S transparency film. Shot using a Nikon F70 35mm SLR
In Yangmingshan National Park, the distribution of hot springs and fumaroles is controlled by a sandstone formation that underlies the 13 geothermal areas. All of Yangmingshan's geothermal activity is confined to a narrow strip between Beitou and Zhishan about 18 kilometers long and 3 kilometers wide. The most active steam vents are those at Tahuangtsui, Siaoyoukeng, Macao, Dayoukeng, Ssuhuangtzuping and Kengtzuping.
Forces inside the earth's crust cause rock to rupture. If rocks on both sides of the fracture move relative to each other, a fault is formed. When surface water seeps down and is heated by an underground heat source, most of it is retained inside porous rock but a small amount rises to the surface along the fissure or fault and emerges as a hot spring. If the water temperature is above boiling point, the water vaporizes underground and emerges as fumarolic steam.
Yangmingshan's popular hot springs can be divided into three types according to their chemical composition. First are the acid sulfate (white sulfur) hot springs, such as those at Tahuangtsui, Jhuzihhu, Ssuhuangtzuping and Kengtzuping. Next are acid sulfate chloride (green sulfur) hot springs, such as the ones at Xin Beitou. Last are neutral iron-bearing hot springs, such as those at Tingpichiao and Lengshuikeng; these are cooler and mostly consist of indirectly heated groundwater.
Enjoying a good soak in a steaming, silky-smooth hot spring set amidst beautiful natural scenery is one of life's greatest pleasures. No wonder so many people make the trip up to Yangmingshan on a regular basis. They wouldn't miss their daily hot spring dip for the world!
硫磺谷是一呈東西向延展的谷地，長約為700公尺。本區南側露出的岩層為五指山層石英砂岩，北側則是新鮮的火成安山岩體。臺灣硫黃產區接近海岸，很早就有人採掘，作為貿易商品輸出。早在元朝汪大淵所撰的《島夷誌略》（1349，元至正九年)一書中，便記載臺灣出產硫磺。「地勢盤穹，林木合抱。山曰翠麓，曰重曼，曰斧頭，曰大崎大崎山極高峻，自彭湖望之甚近。……地產沙金、黃豆、黍子、硫黃、黃蠟、鹿、豹、麂皮。貿易之貨，用土珠、瑪瑙、金珠、粗碗、處州瓷器之屬。海外諸國，蓋由此始。」西班牙統治時期: 「沿淡水河，在Quipatao（北投）一帶，有一些村落出產大量的硫黃.另一個硫黃產地則在Taparri（大巴里）（可能是現在的金山磺山溫泉），當地原住民早在西班牙來之前，就開採大量的硫黃賣給中國人。但是大巴里地區的原住民現在已經停止開礦了，因為他們認為開礦會遭致厄運發生。」鄭氏王朝統治時期: 1659年（明永曆13年），荷蘭通事何廷斌至廈門會見鄭成功，稱許臺灣：「沃野千里，雞籠淡水有硝磺…，真霸王之區也。」勸鄭氏攻取臺灣。閩南紀要就有記載：「而鄭軍之在北投者，竟沾染硫黃，使手足糜爛」。此外，認為「南嵌、淡水，窮年陰霽，硫黃所產毒氣薰蒸」，乃將犯人流放此地。1895日本人據臺後，對於硫黃礦業採用許可制，凡有申請者一律允許開採及自由買賣，清代所立的官營制度完全廢止。在1926年全盛時期，大屯山採硫礦區即有27區。英商德記公司於1897年取得大油坑礦權，由馬歇爾（F.S. Mgrshell）主持。1902年後，收買日人及台人礦區，並改良煉製技術，成為規模最大的採硫單位。日據時代的採硫工作，後來幾乎為德記公司所獨佔。
The name of Yellowstone National Park's "Mud Volcano" feature and the surrounding area is misleading; it consists of hot springs, mud pots and fumaroles, rather than a true mud volcano. Depending upon the precise definition of the term mud volcano, the Yellowstone formation could be considered a hydrothermal mud volcano cluster. The feature is much less active than in its first recorded description, although the area is quite dynamic. Yellowstone is an active geothermal area with a magma chamber near the surface, and active gases are chiefly steam, carbon dioxide, and hydrogen sulfide. However, there are some Mud Volcanoes and Mud Geysers elsewhere in Yellowstone. One, the "Vertically Gifted Cyclic Mud Pot" sometimes acts as a geyser, throwing mud up to 30 feet high.
L'INFERNO ABITA QUI...
A pochi passi da Sasso Pisano, in località Lagoni del Sasso, in prossimità del villaggio Enel è possibile addentrarsi in uno scenario surreale, salendo sulla collina che sovrasta il paese. Soffioni, biancane, putizze, fumarole, sorgenti calde, lagoni, sono visitabili liberamente in quasiasi periodo dell'anno ed è una visita davvero sorprendente.
Se poi non ci si accontenta degli aspetti geologici, a poca distanza, sulla strada che porta a La Leccia, nei pressi del podere "il Bagno", recentemente è stato scoperto un imponente stabilimento termale etrusco-romano con annesso villaggio. Alcuni studiosi attribuiscono particolare imoprtanza a questo sito associandolo alle "Aque Populanie" citate dallo storico romano Plinio e riportate dalla "Tavola Peutingeriana", una mappa stradale dell'impero romano giunta fino a noi grazie a riproduzioni medioevali. Ad oggi gli scavi sono ancora in corso, ma sono state riportate alla luce vaste porzioni dell'impianto termale: sono visibili le vasche, i canali che le alimentavano, colonnati e mura blocchi di arenaria.

Fumaroles are Yellowstone’s hottest and most mysterious geothermal features—steam vents that hiss, roar, and release volcanic gases from deep within the Earth. Unlike geysers or hot springs, they don’t erupt or pool water; instead, they vent pure heat and pressure, often with a sulfuric scent.
🌋 Definition:
Fumaroles are openings in the Earth’s crust that emit steam and volcanic gases like carbon dioxide, sulfur dioxide, and hydrogen sulfide.
• Formation:
They occur where superheated groundwater flashes into steam before reaching the surface. Because they contain very little water, the result is a loud, continuous release of steam and gas.
• Temperature:
Some fumaroles exceed 200°C (392°F), making them the hottest hydrothermal features in Yellowstone.
• Smell & Sound:
The presence of sulfur compounds gives them a “rotten egg” smell, and many roar or hiss audibly—some were once loud enough to be heard miles away.
Thank you for your visit and any faves or comments are always greatly appreciated!

Located above the Datong Bridge along the Yangmingshan-Jinshan Highway, Xiaoyukeng is at an elevation of 800 meters (2,624 ft) and contains a host of volcanically-created fumaroles, sulfur crystals, hot springs, and landslides. Sulfur vents noisily spew forth gases, and hot springs discharge endless streams of boiling water. The bright yellow sulfur crystals that can be seen here are exceptionally lovely. Mt. Cising provides breathtaking views in all directions.

From park signage:
[This area has a] residual mass of cooling andesite lava perhaps 3 miles deep. The "rotten egg" smell is hydrogen sulfide fumes rising from deep within this mass.
Andesite lavas decompose readily but sulfuric acid and hot steam have greatly speeded up the process to carve out this barren, 16-acre bowl.
Bumpass Hell occupies the old eroded vent of a dormant dome volcano - Bumpass Mountain. More than 75 fumaroles, hot springs, and mudpots compose this 16-acre hydrothermal area.
The temperatures of each of the pools may vary. Which is all relative, of course, when "slightly cooler" means 150º Fahrenheit (66º Celsius), instead of 200º Fahrenheit (93º Celsius)!
Big Boiler is the hottest fumarole - within a non-erupting volcano - in the world. The steam temperatures measured here reach as high as 322º Fahrenheit (161º Celsius). That's mighty hot. But for perspective, flowing lava can reach 2,000º Fahrenheit (1,093º Celsius) and the core of the Earth weighs in at a mere 12,000º Fahrenheit (6,648º Celsius).
Constant churning action and heat eat away at surrounding clay banks, enlarging Big Boiler's size. Big Boiler has collapsed a huge portion of the surrounding clay crust since 1915. Just a few years ago, Big Boiler engulfed a portion of the boardwalk that once extended out from here.
Fumaroles or Steam Vents are Top Thermal Areas. Steam and other gases emerge from the feature's vent, sometimes hissing or whistling. Steam Vents are often super-heated, with temperatures as high as 280 degrees Fahrenheit.
The snow looks deep there, by the trench hole. I am not sure what made that...
