Mount Nyiragongo

Mount Nyiragongo is a volcano in the Virunga Mountains associated with the Great Rift Valley. It is located in the Democratic Republic of the Congo, about 19 km north of the town of Goma and the Lake Kivu and just west of the border with Rwanda. The main crater is 250 m deep, two km wide and sometimes contains a lava lake. Nyiragongo and nearby Nyamuragira are together responsible for 40% of Africa's historical volcanic eruptions.
