Multi-centered volcanic field covering 240 km². More than 80 volcanic centres can be distinguished, the products of which are dominantly comenditic with some pantellerite, trachyte and basalt.

A 45 MW power station is operating based on steam produced from the Olkaria Geothermal Field, which is located towards the centre of the complex.
