The Nyamuragira-volcano, also called Nyamlagira, is the most active volcano in Africa.

It is a 3,058 metre high basaltic shield volcano north of Lake Kivu and NW of Nyiragongo, a neighbouring volcano.

Lava from Nyamuragira covers 1,500 square km of the East African Rift.
The crater top is formed as a small 2 x 2.3 km caldera with walls up to 100 m height.
Activity from cracks on the slopes has been known from the previous 30 eruptions since 1882.
A lava lake was active from 1921 but dried out in 1938.
Lava has come as far as 30 km from the volcano, even down to Lake Kivu in the past century.

The volcano is located in the Virunga National Park.
