Volcanoes of Virunga Mountains and Lake Kivu, Rwanda

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.

DRC and Rwanda - July 27th, 2010

This orthorectified image shows several volcanoes near the border of the Democratic Republic of the Congo and Rwanda. All of the volcanoes are located in the Virunga Mountains.

Near the center left is Mount Nyamuragira, an active volcano that is only 13 km north-north-west of Nyiragongo, the volcano which caused extensive damage to the city of Goma in its 2002 eruption.

Mount Nyiragongo, whose main crater is flanked by two other indentations, is a stratovolcano just west of the border with Rwanda. The main crater is about two km wide and usually contains a lava lake.

Moving eastward, one comes to the Mikeno Volcano. Southeast of that peak is Mount Karisimbi, an inactive volcano on the border between Rwanda and the DRC. At 4507 m, Karisimbi is the highest of the eight major mountains of the mountain range.

Karisimbi is flanked to the east by Mount Bisoke, an extinct volcano that straddles the border of Rwanda and the Democratic Republic of the Congo, although the summit is located in Rwanda.

The peak furthest east, near the right edge of the image, is Mount Sabyinyo, an extinct volcano. The summit of the mountain, at 3645 m, marks the intersection of the borders of the DRC, Rwanda, and Uganda.

Volcanoes near Lake Kivu, Rwanda and Congo - January 29th, 2009

Volcanoes near Lake Kivu, Rwanda and Congo - January 29th, 2009

Lake Kivu (bottom) is one of the Great Lakes of Africa. It lies on the border between the Democratic Republic of the Congo and Rwanda.

The populated white area on the northern shore of Lake Kivu is actually two contiguous cities: Goma, in the Democratic Republic of the Congo (west) and Gisenyi, in Rwanda (east).

The lake and the two cities are in the western branch of the Great Rift Valley.

This area also features many volcanoes. In fact, Goma lies only 13 to 18 km (8-11 mi) due south of the crater of the active Nyiragongo Volcano.

Mount Nyiragongo (above Goma) is a volcano in the Virunga Mountains. The main crater is 250 m deep, two km wide and sometimes contains a lava lake.

To the northwest of Nyiragongo lies another volcano, Murara. Murara was a small, short-lived, volcano that began erupting on December 23, 1976. Eruptions from Murara reduced considerably after the eruption of Mount Nyiragongo on January 10, 1977 and ended completely in April 1977.

The other cluster of volcanoes to the northeast is part of the Volcanoes National Park  in northwestern Rwanda, bordering Virunga National Park in the Democratic Republic of Congo and Mgahinga Gorilla National Park in Uganda.

Also famous for its mountain gorillas, Volcanoes National Park is home to five of the eight volcanoes of the Virunga Mountains: (from south to north) Karisimbi, Bisoke, Sabyinyo, Gahinga and Muhabura. These volcanoes are covered in rainforest and bamboo.

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

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.

Democratic Republic of the Congo and Rwanda - January 9th, 2012

This wide-swath ASAR image shows volcanic features around 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 Rift, the western branch of the East African Rift.

Visible as a bright white area on the northern shores of the lake, are the cities of Goma, in the Democratic Republic of the Congo, and Gisenyi, in Rwandu. Goma lies only 18 km due south of the crater of the active Nyiragongo Volcano.

Mount Nyiragongo is a stratovolcano in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo. The main crater is about two km wide and usually contains a lava lake.
