Basic Information

Terrestrial heat flow density (or heat flow in short) is a measure of the surface energy flux from the interior of the Earth. Heat flow study is one of the fundamental geophysical disciplines. It plays an important role in understanding the Earth’s origin, internal constitution, and geodynamic processes. The International Heat Flow Commission (IHFC) is a commission of, and operates generally under guidelines set by the International Association of Seismology and Physics of the Earth's Interior. The International Association of Volcanology and Chemistry of the Earth's Interior, the International Association of the Physical Sciences of the Ocean, and the International Association of the Hydrological Sciences are co-sponsors of the Committee. The scopes of heat flow study are related with the mission of the International Geothermal Association, the International Association of Meteorology and Atmospheric Sciences, and the International Association of Geomagnetism and Aeronomy.
