A geothermal field is any thermally active area that is heated by hot groundwater coming to the surface. This can include areas around hot springs, fumaroles, geysers, hot pools, mudpots, hydrothermal explosion craters, as well as areas of ground that may not be very hot but emit steam or other hot gases that come from ground water that has been heated by underlying hot rocks. The heat source need not be volcanic in origin.

Common/Possible Tagging Mistakes
- natural=hot_spring - A place where natural hot water comes out of the ground.
- natural=geyser - A place where water is periodically ejected under pressure from the ground from a vent as a result of some of the ground water becoming superheated and turning into steam or a build up of a natural gas such as CO2.
