Nella fangaia, alimentata da numerose piccole fumarole e da acqua termale, ribolle alla temperatura di 140° fango naturale, che in passato era utilizzato per la cura dei reumatismi. Trova qui il suo habitat un raro microrganismo termofilo, il Sulfolobus solfataricus.
From the guide:
The fangaia is fed by innumerable small fumaroles and spa water, and the natural mud, which boils at a temperature of 140° C, was considered an excellent remedy for rheumatism. A rare heat-resistant microrganism, the Sulfulobus Solfataricus, has its habitat here.
The Krýsuvík / Seltún geothermal area on the Reykjanes Peninsula in southwest Iceland. Lake Kleyfarvatn can be seen in the distance.
A geothermal region with boiling sulfuric mud springs and steam vents, Námaskarð is located at a short distance from huge volcanic mountain Krafla. Námaskarð, Hverarönd is an expanse of fumaroles, hot springs, mud pools, and mud pots. In this stunning arctic dessert, you will find boiling water and lands. Due to the hot surface, there is no vegetation found at Námaskarð geothermal area. The constant emission of acids has made the surface completely sterile and acidic. The presence of colorful minerals at this site provides an amazing panoramic view. Natural black rivers and boiling pools emitting steam and smoke lay in this colorful landscape are breathtaking. Everything at this acidic land is permeated with Sulphur, even the air, making the area quite distinct.
I had shot this the previous day around noon and was not happy with the result. This was shot in early morning, when it was still cool, making for more steam and more dramatic shadows.

while I was waiting for my bus to Kverfjöll I cycled a few times to Krafla, Dettifoss and of course Namaskard this was taken on my way back from Krafla, I always revisite those hot spots because they change so quickly, is it due to the many tourists or is it just time , but it seems to me that every time I go back there are less hot spots

Southern Peninsula Reykjanesskagi or Reykjanes Peninsula is a region in southwest Iceland. It was named after Reykjanes, the southwestern tip of Reykjanesskagi.
Valles Caldera (or Jemez Caldera) is a 13.7-mile (22.0 km) wide volcanic caldera in the Jemez Mountains of northern New Mexico. Hot springs, streams, fumaroles, natural gas seeps and volcanic domes dot the caldera floor landscape. The highest point in the caldera is Redondo Peak, an 11,253-foot (3,430 m) resurgent lava dome located entirely within the caldera. Also within the caldera are several grass valleys, the largest of which is Valle Grande.
When I lived in Los Alamos many years ago, we were dismayed that it was privately owned and closed to public access. On July 25, 2000, the Valles Caldera National Preserve was created, providing controlled access to this beautiful area. It may become a national park in the next few years, or revert to management by the Forest Service..
Ritchie and I finally made it into the Valles Caldera on our last trip to New Mexico. After a great hike from one edge of the Preserve into the valley, we were treated to a drive down this road through the back of the Caldera.
HFF! Thanks, as always, for stopping by and for all of your kind comments -- I appreciate them all.

These vents and fissures near the upper Te Maari Crater were created during the 6/8/12 and 21/11/12 eruptions. They are still actively steaming after more than four years. The Lower Te Maari Crater that contains a sulphur lagoon within its crater floor can be seen as the well-formed crater behind the steam plumes.

This rather colourful scene gives every clue you need that you ought to beware of the water...
The differently-coloured pools indicate different temperatures and thus different microbial life in each. The colours depend on the ratio of chlorophyll to carotenoids and on the temperature gradient in the run-off. And the water needs to be HOT to generate that density of microbial life.
And if that's not enough, note the fumarole on the far bank of the pools on the right. Fumaroles are ground openings in geothermally-active areas which emit steam and gases such as carbon dioxide, sulphur dioxide, hydrogen chloride, and hydrogen sulphide.
Of course, a wider view would have given you the full context. This image was taken in the Norris Geyser Basin of Yellowstone National Park, the most geothermally-active and hottest (up to 138˚C) part of the park - the area seen above is perhaps one of the tamer parts of that area!
Strokkur Geysir is located in the Haukadalur valley area, where various other geothermal features such as mud pools, fumaroles and other geysers are located.

This is exactly how the kitchen looks, when in spite of my limited culinary skills, I venture into Neha's domain, i.e. her kitchen & misadventure a "Sunny Side Up!" :)
Yellowstone National Park, Upper Geyser Basin is spectacular with it's colorful thermophillic micro organism mats that thrive in the hot geyser basins.
The Fountain Paint Pot area in Yellowstone has several springs, pools, geysers, a fumarole, and the Fountain Paint Pot. Yellowstone National Park.
This trail is an easy 0.5 mile (0.8 km) loop boardwalk. You will see various hydrothermal features that are expressions of Yellowstone's volcanism. No two features are exactly alike, yet they can be grouped into those with a lot of water (hot springs and geysers) and those with limited water (mud pots and fumaroles).

Swimming is banned since 14 people have died since 1968 and more injured.
Landmannalaugar long trail, a place rich of colored hills and active fumarole, where you can alternate snowy landscapes with hotsprings. Kinda paradise. This is Iceland!
Steam comes up through small fumaroles in an area of altered and slightly altered volcanic rock in the Gunnuhver Thermal Group on the Reykjanes Peninsula in Iceland. This dynamic, high temperature geothermal area changes often with hydrothermal features coming and going over its recorded history. Reykjanes is unstable due to earthquakes, which occur in swarms. Most are rather small with the largest measured just over magnitude 5. Some have caused a minor slip on a fissure that passes through Gunnuhver and Kísilhóll. The last earthquake occurred about 40 years ago. Such ground movements revive the steam field intermittently and allow the deep reservoir water and steam to escape to the surface creating short-lived geysers, thermal springs. and fumaroles.
Seawater makes up the deep reservoir fluid that enters the hot springs. This is a unique situation in Iceland and a rare occurrence in the world. The water rich in dissolved chlorides, sulfur and silica other minerals deposits sinter, native sulfur and other sulphate minerals (mostly white in color) including tamarugite (a sodium sulfate). In the foreground of this photo sulphates can be seen encrusting the ground around small fumaroles. The hydrothermal features like fumaroles, mud pots and erupting springs form where steam generated by boiling in a geothermal reservoir emanates and condenses and mixes with surface water. Accompanying gases such as carbon dioxide and hydrogen sulphide make the water acidic, which causes alteration of the fresh basalt to clay.
Eine Landschaftsaufnahme des Vulkans El Misti in der Nähe von Arequipa, Peru. Der massive, kegelförmige Vulkan dominiert die Szene und erhebt sich über einer trockenen, ockerfarbenen Hochebene im Vordergrund. Am Gipfel des Vulkans ist eine kleine Rauch- oder Dampfwolke (Fumarole) zu erkennen. Der Himmel ist klar und tiefblau, mit einer einzigen, markanten weissen Cumuluswolke, die links über dem Gipfel schwebt.
Steam from fumaroles rise along the Steaming Bluff (Wahinekapu) on the west rim of Kilauea's Summit Caldera in Hawai'i Volcanoes National Park.
Wonderful sunrise at Hverarond geothermal area near Myvatn in Northern Iceland. With bubbling mud pools and steaming fumaroles it looks like a scene from the early days of Earth...
Bumpass Hell, which is a hydrothermally altered geothermal area that is in Lassen Volcanic National Park, and has hot springs, fumaroles, and boiling mud pots.

The Upper Geyser Basin, about two square miles in area, contains the largest concentration-nearly one-quarter- of all the geysers in the world. A wide variety of other thermal features also exist here, including colorful hot springs, thundering fumaroles and violent boiling springs.Morning Glory Pool, which is named due to it's likeness to the flower, is one of the most brilliantly hued hot water springs of the Yellowstone region. There is a well marked trail which starts from the Old Faithful Geyser near the same named Inn & takes you through some of the most amazing hot water springs & geysers.
The Morning Glory Pool has changed colors over the last few years as people keep on vandalizing it by throwing literally tons of coins, trash, rocks, and logs into the pool. Much of the debris subsequently became embedded in the sides and vent of the spring, affecting water circulation and accelerating the loss of thermal energy. Through the years Morning Glory's appearance has changed as its temperature dropped. Orange and yellow bacteria that formerly colored only the periphery of the spring now spread toward its center.
