Lardarello is a geyser in Southern Europe, in the central region of the Metalliferous Hills in Tuscany, Italy. They are hot springs and give off continuous bursts of steam.

Geothermal power production

This site is home to one of the largest and oldest geothermal power stations [1] and has been producing this power since 1904.

How the springs form

The heat source that drives power is located below the surface in metamorphic rocks. This turns the water to steam which is then trapped because of the impermeable shales and clay. These trap the steam as they are folded in a dome shape. The steam then escapes because of faults in the dome shape and the steam forces its way out in the hot spring we see.
