Geothermal Map of Switzerland 1:500000

The geothermal map shows the thermal energy that is produced in the subsurface and traverses the Earth's surface within an area of 1 m2 (mW/m2). The heat flow data is calculated from the temperature gradient (average value approx. 30 K/km) and heat conductivity of the rock (average value approx. 3 W/(m·K). The heat itself is released in the Earth's crust (ca. 30 km thick) generally by radioactive decay processes. On average, the heat flow in Switzerland is around 90 mW/m2. The highest figures are found in northern Switzerland and the lowest in the Alps/Jura. Differences are caused by deep groundwater circulating in permeable rock strata. - Source: F. MEDICI & L.
