A hot spring is a spring produced by the emergence of geothermally heated groundwater that rises from the Earth's crust. There are geothermal hot springs in many locations all over the crust of the earth.
Definitions
![](http://upload.wikimedia.org/wikipedia/commons/thumb/c/c6/Natural_iron_hot_spring.jpg/170px-Natural_iron_hot_spring.jpg)
There is no universally accepted definition of a hot spring. For example, one can find the phrase hot spring defined as
- any geothermal spring[1]
- a spring with water temperatures above its surroundings[2]
- a natural spring with water temperature above body temperature – normally between 36.5 and 37.5 °C (97.7 and 99.5 °F)[3]
- a natural spring with warm water above body temperature[4]
![](http://upload.wikimedia.org/wikipedia/commons/thumb/e/e7/GM_Guelma_Hammam_Challala01.jpg/220px-GM_Guelma_Hammam_Challala01.jpg)
- a thermal spring with water warmer than 36.7 °C (98 °F)[5][6]
- a natural spring of water greater than 21.1 °C (70 °F) (synonymous with thermal spring)[7][8][9][10]
- a natural discharge of groundwater with elevated temperatures[11]
- a type of thermal spring in which hot water is brought to the surface. The water temperature of a hot spring is usually 6.5 °C (12 °F) or more above mean air temperature.[12] Note that by this definition, "thermal spring" is not synonymous with the term "hot spring"
- a spring whose hot water is brought to the surface (synonymous with a thermal spring). The water temperature of the spring is usually 8.3 °C (15 °F) or more above the mean air temperature.[13]
- a spring with water above the core human body temperature – 36.7 °C (98 °F).[14]
- a spring with water above average ambient ground temperature[15]
- a spring with water temperatures above 50 °C (122 °F)[16]
![](http://upload.wikimedia.org/wikipedia/commons/thumb/4/43/HotSpring_8344.jpg/220px-HotSpring_8344.jpg)
The related term "warm spring" is defined as a spring with water temperature less than a hot spring by many sources, although Pentecost et al. (2003) suggest that the phrase "warm spring" is not useful and should be avoided.[14] The US NOAA Geophysical Data Center defines a "warm spring" as a spring with water between 20 and 50 °C (68 and 122 °F).
Sources of heat
Water issuing from a hot spring is heated geothermally, that is, with heat produced from the Earth's mantle. In general, the temperature of rocks within the earth increases with depth. The rate of temperature increase with depth is known as the geothermal gradient. If water percolates deeply enough into the crust, it will be heated as it comes into contact with hot rocks. The water from hot springs in non-volcanic areas is heated in this manner.
![](http://upload.wikimedia.org/wikipedia/commons/thumb/4/4d/Crepuscular_rays_and_Dead_trees_at_Mammoth_Hot_Springs.jpg/220px-Crepuscular_rays_and_Dead_trees_at_Mammoth_Hot_Springs.jpg)
In active volcanic zones such as Yellowstone National Park, water may be heated by coming into contact with magma (molten rock). The high temperature gradient near magma may cause water to be heated enough that it boils or becomes superheated. If the water becomes so hot that it builds steam pressure and erupts in a jet above the surface of the Earth, it is called a geyser. If the water only reaches the surface in the form of steam, it is called a fumarole. If the water is mixed with mud and clay, it is called a mud pot.
Note that hot springs in volcanic areas are often at or near the boiling point. People have been seriously scalded and even killed by accidentally or intentionally entering these springs.
Warm springs are sometimes the result of hot and cold springs mixing. They may occur within a volcanic area or outside of one. One example of a non-volcanic warm spring is Warm Springs, Georgia (frequented for its therapeutic effects by paraplegic U.S. President Franklin D. Roosevelt, who built the Little White House there).
Flow rates
![](http://upload.wikimedia.org/wikipedia/commons/thumb/f/f2/Islande_source_Deildartunguhver.jpg/170px-Islande_source_Deildartunguhver.jpg)
Hot springs range in flow rate from the tiniest "seeps" to veritable rivers of hot water. Sometimes there is enough pressure that the water shoots upward in a geyser, or fountain.
High flow hot springs
There are many claims in the literature about the flow rates of hot springs. It should be noted that there are many more high flow non-thermal springs than geothermal springs. For example, there are 33 recognized "magnitude one springs" (having a flow in excess of 2,800 L/s (99 cu ft/s) in Florida alone. Silver Springs, Florida has a flow of more than 21,000 L/s (740 cu ft/s). Springs with high flow rates include:
- The Excelsior Geyser Crater in Yellowstone National Park yields about 4,000 U.S. gal/min (0.25 m3/s).
- Evans Plunge in Hot Springs, South Dakota has a flow rate of 5,000 U.S. gal/min (0.32 m3/s) of 87 degree spring water. The Plunge, built in 1890, is the world's largest natural warm water indoor swimming pool.
- The combined flow of the 47 hot springs in Hot Springs, Arkansas is 35 L/s (1.2 cu ft/s).
- The hot spring of Saturnia, Italy with around 500 liters a second[17]
- The combined flow of the hot springs complex in Truth or Consequences, New Mexico is estimated at 99 liters/second.[18]
- Lava Hot Springs in Idaho has a flow of 130 liters/second.
- Glenwood Springs in Colorado has a flow of 143 liters/second.
- Elizabeth Springs in western Queensland, Australia might have had a flow of 158 liters/second in the late 19th century, but now has a flow of about 5 liters/second.
- Deildartunguhver in Iceland has a flow of 180 liters/second.
- The hot springs of Brazil's Caldas Novas ("New Hot Springs" in Portuguese) are tapped by 86 wells, from which 333 liters/second are pumped for 14 hours per day. This corresponds to a peak average flow rate of 3.89 liters/second per well.[citation needed]
- The 2,850 hot springs of Beppu in Japan are the highest flow hot spring complex in Japan. Together the Beppu hot springs produce about 1,592 liters/second, or corresponding to an average hot spring flow of 0.56 liters/second.
- The 303 hot springs of Kokonoe in Japan produce 1,028 liters/second, which gives the average hot spring a flow of 3.39 liters/second.
- The Oita Prefecture has 4,762 hot springs, with a total flow of 4,437 liters/second, so the average hot spring flow is 0.93 liters/second.
- The highest flow rate hot spring in Japan is the Tamagawa Hot Spring in Akita Prefecture, which has a flow rate of 150 liters/second. The Tamagawa Hot Spring feeds a 3 m (9.8 ft) wide stream with a temperature of 98 °C (208 °F).
- There are at least three hot springs in the Nage region 8 km (5.0 mi) south west of Bajawa in Indonesia that collectively produce more than 453.6 liters/second.
- There are another three large hot springs (Mengeruda, Wae Bana and Piga) 18 km (11 mi) north east of Bajawa, Indonesia that together produce more than 450 liters/second of hot water.
- The Dalhousie Springs complex in Australia had a peak total flow of more than 23,000 liters/second in 1915, giving the average spring in the complex an output of more than 325 liters/second. This has been reduced now to a peak total flow of 17,370 liters/second so the average spring has a peak output of about 250 liters/second.[19]
- In Yukon’s Boreal Forest, 25 minutes north-west of Whitehorse in northern Canada, Takhini Hot Springs flows out of the Earth’s interior at 385 L/min (85 imp gal/min; 102 US gal/min) and 47 °C (118 °F) year-round.[20]

Because heated water can hold more dissolved solids than cold water, warm and especially hot springs often have very high mineral content, containing everything from simple calcium to lithium, and even radium. Because of both the folklore and the claimed medical value some of these springs have, they are often popular tourist destinations, and locations for rehabilitation clinics for those with disabilities.[21][22][23]
Biota in hot springs
A thermophile is an organism — a type of extremophile — that thrives at relatively high temperatures, between 45 and 80 °C (113 and 176 °F).[24] Thermophiles are found in hot springs, as well as deep sea hydrothermal vents and decaying plant matter such as peat bogs and compost.
![](http://upload.wikimedia.org/wikipedia/commons/thumb/8/8e/Algal_mats_on_hot_pool%2C_Orakei_Korako_1.jpg/220px-Algal_mats_on_hot_pool%2C_Orakei_Korako_1.jpg)
Some hot springs biota are infectious to humans. For example:
- Naegleria fowleri, an amoeba, live in warm waters and soils worldwide and may cause meningitis.[25][26] Several deaths have been attributed to this amoeba, which enters the brain through the nasal passages.[27][28]
- Acanthamoeba also can spread through hot springs, according to the US Centers for Disease Control.[29]
- Legionella bacteria have been spread through hot springs.[30][31]
- Viruses have been collected from very extreme environments, for example, a hot spring with a temperature of 87 to 93 °C (189 to 199 °F) and an incredibly acidic pH of 1.5 in Pozzuoli, Italy. These viruses were observed to infect cells in the laboratory.[32]

There are hot springs in many countries and on all continents of the world. Countries that are renowned for their hot springs include China, Costa Rica, Iceland, Iran, Japan, New Zealand, Peru, Taiwan, Turkey, and United States, but there are hot springs in many other places as well:
- Many little ancient villages exist in Catalonia with thermal tradition like Caldes de Malavella, Caldes de Montbui, Caldes d'Estrac, and Caldes de Boí.
- The Frying Pan Lake in Waimangu Volcanic Rift Valley, New Zealand, the world's largest hot spring.
- The Boiling Lake hot spring in Dominica. It is the second largest hot spring in the world.
- The Geysir hot springs in Iceland are the source of the word "geyser".
- The town of Spa, Belgium is the origin of the word "spa" and features springs with water temperatures of 32 °C (90 °F). Casanova visited Spa in 1783 looking for business opportunities but was disappointed.[33]
- The Jordan spring in Bad Oeynhausen, Germany, was drilled in 1926. With a depth of 725 m and 3000 l/min it is the largest carbonated brine water source in the world 36 °C (97 °F).[34]
- Aachen, Germany has one of the hottest springs of continental Europe with water temperatures of 74 °C (165 °F). The hottest spring of continental Europe is in Sapareva Banya, Bulgaria (103 °C (217 °F)).
- The Yangbajing hot springs field about 87 km. north of Lhasa in Tibet is several square kilometers in size, and used to supply a large fraction of the electricity of Lhasa. At an altitude between 4,290 and 4,500 m (14,070 and 14,760 ft), this is a strong candidate for the set of highest altitude hot springs on earth.
- Icaria, Greece features a radioactive hot water spring that has been used since the 4th century BC.
- There are numerous hot springs in Greenland, such as on Uunartoq island near Alluitsup Paa. There are over 2000 hot springs just on Disko Island, which has an area only 0.4% of that of Greenland.
- Widely renowned since a chemistry professor's report in 1918 classified them as one of the world's most electrolytic mineral waters, the Rio Hondo Hot Springs in northern Argentina have become among the most visited on earth.[35] The Cacheuta Spa is another famous hot springs in Argentina.
- Iceland has many famous hot springs, including the one feeding the Blue Lagoon spa in Grindavík, Iceland, and Europe's highest flow rate hot spring Deildartunguhver. Deildartunguhver's water emerges at 97 °C (207 °F) and is piped many miles to heat neighboring towns.
- One of the highly potential geothermal energy reservoirs in India is the Tattapani thermal springs of Madhya Pradesh.[36][37]
- Shiretoko National Park in Hokkaidō, Japan has a hot springs waterfall called Kamuiwakkayu-no-taki, which translates as "river of the gods" in the Ainu language.
- Northwest Spitsbergen National Park, Spitsbergen at 80 degrees north, contains two of earth's most northerly hot springs.
- There are many geothermal springs in the UK, but the thermal springs found in the town of Bath produce the highest temperature geothermal water in the UK.
- Oymyakon in eastern Siberia is a candidate for the coldest permanently inhabited location in the Northern Hemisphere and another hot springs site. The Yakut language word "oymyakon" means "river doesn't freeze" after the local tributary of the Indigirka River fed by the hot springs which continues to flow year round in this permafrost region.
- Bela-Bela (formerly Warmbaths) in Limpopo Province, South Africa.
- Sirch (Kerman), Sar'eyn (Ardabil), Geno (Bandar Abbas) and gheinarjeh (Ardabil) with 86 °C (187 °F) are notable hot springs in Iran.
- Hot Springs National Park has 47 hot springs at Hot Springs Mountain in the town of Hot Springs, Arkansas USA.
- Lake Hévíz is close to the city of Hévíz, Hungary. Is the second largest thermal lake in the world. The lake water temperatures range between 23-25 °C in winter and 33-36 °C in summer.
- Takhini Hot Springs is the only developed hot spring in the Yukon, Canada. Its water flows from deep within the earth with a temperature of around 47 °C.
- El Pandeño in Julimes, Chihuahua, Mexico, harbors the entire known population of Julimes pupfish (Cyprinodon julimes) which shares its habitat with other rare micro-endemic species. The Julimes pupfish is considered to be the freshwater teleost that lives at the highest temperatures on the planet,[38] and possibly also the vertebrate with the smallest known distribution range.[39]
Etiquette
Depending on the hot spring you attend will depend on the customs and practices you must observe. It is common practice that bathers should wash before entering the water so as not to contaminate the water (with/without soap). In many countries, like Taiwan, it is required that you enter the hot spring with no clothes on, including swimwear. Typically in these circumstances, there are different facilities or times for men and women. In some countries, if it is a public hot spring, swimwear is required.[citation needed]
