About Ol doinyo Lengai

Ol Doinyo Lengai & Lake Natron – 4 Days

Oldoinyo Lengai is an active volcano located in Tanzania, East Africa. Its name means “Mountain of God” in the Maasai language.

Oldoinyo Lengai is unique because it is one of the few volcanoes in the world that produces natrocarbonatite lava, which is very different from the more common basaltic lava. The lava is very fluid and has a low viscosity, meaning that it can flow much more easily than other types of lava. It is also much cooler than other types of lava, with temperatures ranging from 500 to 600 degrees Celsius, compared to the 1,000 to 1,200 degrees Celsius of basaltic lava.

Due to its unique composition, Oldoinyo Lengai’s eruptions are not very explosive and do not produce large ash clouds or pyroclastic flows. Instead, the lava flows down the volcano’s steep slopes and spreads out in a thin layer, creating a flat and often hard surface.

Oldoinyo Lengai is considered to be an active volcano, with regular eruptions occurring every few years. While it is not as well-known as other famous volcanoes like Mount Fuji or Mount Vesuvius, it is still an important geological and cultural landmark in Tanzania.
