Definitions

 
"Blood Pond" hot spring in Beppu, Japan

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 human body temperature – which is normally between 36.5和37.5 °C（97.7和99.5 °F）[3]
  • a natural spring with warm water above body temperature[4]
 
Hammam Maskhoutine（英语：Hammam Maskhoutine） in Algeria
  • 地熱泉 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]
 
Hot spring in Lassen Volcanic National Park

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和50 °C（68和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.

 
Steam Crepuscular rays at Mammoth Hot Springs（英语：Mammoth Hot Springs）

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（英语：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（英语：paraplegic） U.S. President Franklin D. Roosevelt, who built the Little White House there).

Flow rates

 
Deildartunguhver（英语：Deildartunguhver）, Iceland: the highest flow hot spring in Europe

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. 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（英语：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（英语：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 °F（31 °C） 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（英语：Saturnia）, Italy with around 500 liters a second[17]
  • The combined flow of the hot springs complex in Truth or Consequences, New Mexico（英语：Truth or Consequences, New Mexico） is estimated at 99 liters/second.[18]
  • Lava Hot Springs（英语：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（英语：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.[來源請求]
  • 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.
  • Ōita 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（英语：Tamagawa Hot Spring） in Akita Prefecture, which has a flow rate of 150 liters/second. The Tamagawa Hot Spring feeds a 3米（9.8英尺） wide stream with a temperature of 98 °C（208 °F）.
  • There are at least three hot springs in the Nage（英语：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（英语：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（英语：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]

Therapeutic uses

 
Japanese open air hot spring (onsen) in Nachikatsuura, Wakayama
 
Hammam Essalihine（英语：Hammam Essalihine）, Roman hot spring in Algeria

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

主条目：Thermophile

A thermophile is an organism — a type of extremophile — that thrives at high temperatures, between 45、80 °C（113、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.

主条目：List of hot springs

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:

 
Chaudes-Aigues-Lavoir
  • The springs in Europe with the highest temperatures are located in France, in a small village named Chaudes-Aigues.[來源請求] Located at the heart of the French volcanic region Auvergne, the thirty natural hot springs of Chaudes-Aigues have temperatures ranging from 45° C (113° F) to more than 80° C (176° F). The hottest one, the "Source du Par", has a temperature of 82° C (179.6° F). The hot waters running under the village have provided heat for the houses and for the church since the 14th Century. Chaudes-Aigues (Cantal, France) is a spa town known since the Roman Empire for the treatment of rheumatism.
  • One of the highly potential geothermal energy reservoirs in India is the Tattapani thermal springs of Madhya Pradesh.[34][35]

Etiquette

The customs and practices observed differ depending on the hot spring. It is common practice that bathers should wash before entering the water so as not to contaminate the water (with/without soap).[36] In many countries, like Japan, it is required to 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.[來源請求]
