The world's coolest volcano

Ol Doinyo Lengai, active volcano in Arusha, Tanzania, is located at an altitude of 2,890m, with lava eruptions with temperatures lower than half normal.

Lava eruption with less than half the normal heat causes Ol Doinyo Lengai to be the coolest volcano in the world.

Most volcanic ranges on earth produce basalt lava, but Ol Doinyo Lengai produces natrocarbonatite lava - nyerereite-rich lava and gregoryite.

Under the sun, this lava layer appears black instead of the usual red color like other volcanoes.

The temperature of the volcano Ol Doinyo Lengai is only 500 - 600 degrees C.

Two types of minerals in volcanic lava Ol Doinyo Lengai react quickly when exposed to air.

Black or dark brown lava and ash here will turn white after a few hours of volcanic eruptions and quickly become minerals capable of absorbing water.

Also because this lava layer contains less silicon, it has no viscosity and is easily melted.

The colors change.

Small cone tips at the crater often create small, harmless eruptions, accompanied by tiny lava layers that fire around looking quite nice.

This volcano is located at an altitude of 2,890m and is interpreted by the natives as 'The Mountain of God'.
