Rwanda - December 10th, 2011

This orthorectified image shows Lake Kivu, one of the African Great Lakes. It lies on the border between the Democratic Republic of the Congo and Rwanda, and is in the Albertine (western) Rift, a part of the Great Rift Valley.

The lake covers a total surface area of some 2,700 km2 (1,040 sq mi) and stands at a height of 1,460 metres (4,790 ft) above sea level. Some 1 370 km2 or 58% of the lake’s waters lie within DRC borders. The lake bed sits upon a rift valley that is slowly being pulled apart, causing volcanic activity in the area, and making it particularly deep: its maximum depth of 480 m (1,575 ft) is ranked eighteenth in the world. The lake is surrounded by mountains.

Northeast of Lake Kivu are several volcanoes, all of which are part of the Virunga Mountains. Closest to the lake’s shores is Mount Nyiragongo, whose main crater is flanked by two other indentations. It is a stratovolcano that lies just west of the border with Rwanda.

Moving to the right, one can see the Mikeno Volcano, Mount Bisoke and Mount Karisimbi (clockwise from left) grouped together. In the upper right corner is Mount Sabyinyo, an extinct volcano. The summit of the mountain, at 3645 m, marks the intersection of the borders of the Democratic Republic of the Congo, Rwanda, and Uganda.

Volcanoes on border of Rwanda and the Democratic Republic of the Congo - January 13th, 2009

The Virunga Mountains are a chain of volcanoes in East Africa, along the northern border of Rwanda, the Democratic Republic of the Congo (DRC) and Uganda.

The mountain range is a branch of the Albertine Rift, a part of the Great Rift Valley. They are located between Lake Edward and Lake Kivu, partially visible at the bottom left.

The mountain range consists of eight major volcanoes. Most of them are dormant, except Mount Nyiragongo (3462 m) and Mount Nyamuragira (3063 m) in the Congo. Mount Karisimbi (4507 m) is the highest volcano. The oldest mountain is Mount Sabyinyo (3634 m).

The Virunga Mountains are home of the critically endangered mountain gorilla, listed on the IUCN Red List of Endangered Species due to habitat loss, poaching, disease, and war.

Mount Nyiragongo, visible at the top right, has been described as Africa’s most active volcano. Mount Nyamuragira can be identified by its twin craters; the main crater is 250 m deep, two km wide and sometimes contains a lava lake.

Together, these two volcanoes have been responsible for 40% of Africa’s historical volcanic eruptions. They erupted most recently in 2006.

Mount Karisimbi, the southernmost volcano in the image, is the highest of the eight major mountains, at 4507 m (14,787 ft). It is flanked by Mikeno to the north and Bisoke to the east.

The summit of Mount Sabyinyo (also Sabinyo, Sabinio), far right, marks the intersection of the borders of the Democratic Republic of the Congo, Rwanda, and Uganda.
