Outstanding geysers around the world

Below are listed selected geysers of the world. They are arranged by the part of the world and in an alphabetic order:


  • Allalobed geysers and hot springs – Afar, Ethiopia. Group of beautiful hot springs and very active, up to 6 m high (sometimes even 30 m) geyser.
  • Analavory geysers – Itasy, Madagascar. Cold geysers! Four warm gaseous water "geysers" with colourful cones. The water for these spouting springs reportedly is coming from the pipelines of the nearby mine – on the way the hot water is dissolving the lime and depositing it at the outflow. When the vents of outflow are blocked, the water may rise up to several meters high, but otherwise the water spouts 20 – 30 cm high.
  • Buranga Hot Springs (Sempaya Hot Springs) – Western Region, Uganda. Perpetual spouter! The most impressive geothermal region in Uganda with hot springs and a geyser-like fountain of hot water – Mumbuga erupting spring. In dry season here appear also fumaroles.
  • Dallol hot springs and geysers – Afar, Ethiopia. One of the visually most outstanding places on Earth, the hot springs have a high salt concentration, which has shaped terraces and other formations of very bright, unusual colors. Among the hot springs there is also salt geyser – possibly the only one in the world.
  • Loburu geysers and other geysers of Lake Bogoria – Rift Valley, Kenya. In several geothermal areas around the Lake Bogoria there are more than 10 active geysers, up to 5 m high.

  • Beppu hot springs – Oita prefecture, Japan. A group of boiling mud pots and hot pools – jigoku. Tatsumaki jigoku geyser erupts up to 20 m high. Whole area long since ago has been turned into resort and it is not easy to distinguish what here is man-made and what – natural.
  • Chaluo geysers – Sichuan, China. Group of fumaroles, boiling springs and 4 geysers.
  • Dagejia geysers (Dagyel Chuja, Tagejia, Tagajia, Dagajia) – Shigatse. The largest geyser field in Tibet with some 20 active geysers. Dagejia Pohutu Geyser spouts up to 20 m high and is the most powerful geyser in Asia. Geysers have formed nearly unique cesium containing deposits.
  • Fang Hot Springs – North, Thailand. Group of boiling springs, some are periodicaly spouting a fountain of boiling water and steam. Earlier here was a geyser.

  • Onikobe geysers – Miyagi prefecture, Japan. In this location geysers are known for at least 1,700 years, but natural geysers have gradually weakened. Now the largest is Benten – Onikobe Geyser, which has formed in man-made borehole. It is erupting up to 8 m high. Nearby are some more springs with fountains.
  • Peting Chuja and Naisum Chuja – Tibet. Some of most mysterious and less known geyser fields in the world, located in hard to access valley of La Chu (Laha) River. It is considered that here are some 14 active geysers. Naisum Chuja at the end of the 19th century had two geysers spouting up to 18 m high. During the harsh Tibetan winter the water freezes, forming weird ice towers.

What are natural geysers?

Hasty hydrogeologist would say: geysers are thermodynamically and hydrodynamically unstable hot springs. "Normal" people would say – geysers are hot springs which at more or less regular intervals shoot up a fountain of boiling water and steam. Sometimes these fountains are even 100 m tall… or even 450 m!

A recipe for a natural geyser

Geysers are a rarity – there are just a few places in the world with true geysers. This is because there are needed four preconditions for a proper geyser:

  • Constant supply of ground water. Permanent flow of groundwater is not that common on Earth – many locations are too dry for this. Continuous flow of groundwater is rare on the summits of volcanoes – locations, which otherwise would be good candidates for geysers. Sometimes not too much groundwater is needed – the climate around El Tatio geysers (Chile) is dry but geysers here are economical and reuse most of the water.
  • Source of heat – magma close to the ground surface – close enough to heat the groundwater above the point of boiling. One should remember that higher up in the mountains the boiling point is at lower temperature, f.e. in Yellowstone (2300 m above the sea level) the boiling point is at 93° C.
  • Suitable configuration of groundwater reservoir. Underground reservoirs of geysers are very hard to access, but research thus far shows, that reservoirs of geysers might be very complex, consisting of smaller channels and large voids.
  • Tough surrounding rocks. The hydrothermal processes in the geyser create high pressure and fragile rocks quickly lead to collapse of geyser. Even the sturdiest rocks can not last these pressures forever – due to this the life time of most geysers is not very long. Most geysers of the world have formed in rhyolite – a specific volcanic rock with a similar chemical composition to granite.
How works a geyser?

When the temperature of water exceeds a boiling point, water turns into steam which takes at least 1500 times more space than the water. If the boiling point is exceeded in the whole mass of water, an explosion happens.

Thus – after the eruption of geyser the reservoir has been emptied. Colder water starts to fill up the reservoir – and it starts to heat up. At some moment whole reservoir is filled with water. At the deepest part of the reservoir the rocks are hotter and water gets heated beyond the point of boiling. The pressure of the water column above it at first does not allow for the steam to rise up.

Now the water column in the geyser is unstable – and even a single bubble or small stone leads to a sudden eruption, or the eruption starts by itself at certain moment. The steam suddenly pulls upwards and together with the upper layers of the water flies up in the air. As the water column gets rid of the colder layers of water, the remaining steam also blows up. This continues for some time, until the geyser reservoir is empty. Now it can start again…

Types of geysers

There are distinguished two kinds of natural geysers:

  • Cone geysers are erupting from the summit of a small cone – they look like small volcanoes. This cone is shaped by geyser itself and consists of geyserite – siliceous rock. Geysers in Dallol (Ethiopia) though have created cones of salt.
  • Fountain geysers are beautiful pools without bottom, filled with unusually lucid water. These pools erupt with splashing action.

What are perpetual spouters?

There are springs which permanently shoot up a boiling water and steam. Here the mechanism is simpler – as the water gets in the reservoir, it is turned into steam almost instantly and is blown up in the air.

Such springs are very interesting natural landmarks – but they are not geysers. Geysers have periodic, visually very impressive explosions, perpetual spouters are permanent and not high.

Unfortunately most tourists and, what is worse – tourism industry – calls them geysers. Wrong!

What are cold water geysers?

Water in many springs is rich with carbon dioxide. If the configuration of the spring reservoir is similar to the one of true geysers, the effect can be similar: at the depth of spring reservoir is accumulated the CO2 gas. It can not rise upwards due to the pressure of water column above it. At some moment the pressure gets that high, that the water column above the gas is pushed upwards, like a cork from the bottle of champagne. Ola! A fountain of genuine carbonated water gets off!

Cold water geysers are man-made – these are just boreholes which have reached deep layers of carbonated water. Sometimes the upper end of the metallic borehole gets covered with sediments of lime and dissolved iron from the borehole itself – there forms a weird looking cone in orange and brown color.

In some of these springs the water is not cold – it might be even hot. Nevertheless they are powered by carbon dioxide and not steam.

These landmarks are partly artificial and definitely: not true geysers.

Geysers: What they are and How They Work

In Geysers: What They Are and How They Work, T. Scott Bryan explains the geological setting that produces the pressure, heat, and abundant water necessary for a geyser to form and introduces readers to the variables that shape each geyser’s distinct personality. Some geysers spout just inches above a pool of water and others blast hundreds of feet in the air from conical vents. Some remain quiet for decades only to explode unexpectedly several times in a single month while others regularly erupt at scheduled intervals.

The Geysers of Yellowstone, Fifth Edition

This new edition of The Geysers of Yellowstone is the most up-to-date and comprehensive reference to the geysers of Yellowstone National Park, describing in detail each of the more than five hundred geysers in the park. The entire text has been revised and geyser descriptions have been updated based on activity observed through early 2018. Information about a number of significant new geyser developments has been added, as well as recent knowledge about some of the world’s geyser fields outside Yellowstone.
