Context: The Virunga Mountains (also known as Mufumbiro) 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 Mountains, which border the western branch of the East African Rift. They are located between Lake Edward and Lake Kivu. The name "Virunga" is an English version of the Kinyarwanda word "ibirunga", which means "volcanoes"., The Democratic Republic of the Congo , also known as DR Congo, DRC, DROC, East Congo, Congo-Kinshasa, or simply the Congo is a country located in Central Africa. From 1971 to 1997 it was named, and is sometimes still called Zaire, and from 1908 to 1960 it was called the Belgian Congo. The DRC borders the Central African Republic, and South Sudan to the north; Uganda, Rwanda, Burundi and Tanzania to the east; Zambia and Angola to the south; the Republic of the Congo to the west and the Atlantic Ocean to the southwest. It is the second-largest country in Africa by area and eleventh largest in the world. With a population of over 80 million, the Democratic Republic of the Congo is the most populated officially Francophone country, the fourth most-populated nation in Africa and the eighteenth most populated country in the world., Nyamuragira (Derived from the Kinyarwanda verb 'Kuragira inka', meaning to "herd cows"; Inka means "cow" or "cows") is an active volcano in the Virunga Mountains of the Democratic Republic of the Congo, situated about 25 km north of Lake Kivu., The Virunga National Park, formerly named Albert National Park, is a National Park that stretches from the Virunga Mountains in the south, to the Rwenzori Mountains in the north, in the eastern Democratic Republic of the Congo, bordering Volcanoes National Park in Rwanda and Rwenzori Mountains National Park and Queen Elizabeth National Park in Uganda., Lake Kivu is 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. Lake Kivu empties into the Ruzizi River, which flows southwards into Lake Tanganyika., Rwanda (or ), officially the Republic of Rwanda, is a sovereign state in central and east Africa and one of the smallest countries on the African mainland. Located a few degrees south of the Equator, Rwanda is bordered by Uganda, Tanzania, Burundi and the Democratic Republic of the Congo. Rwanda is in the African Great Lakes region and is highly elevated; its geography is dominated by mountains in the west and savanna to the east, with numerous lakes throughout the country. The climate is temperate to subtropical, with two rainy seasons and two dry seasons each year., Mount Nyiragongo is an active stratovolcano with an elevation of in the Virunga Mountains associated with the Albertine Rift. It is located inside Virunga National Park, in the Democratic Republic of the Congo, about north of the town of Goma and Lake Kivu and just west of the border with Rwanda. The main crater is about two kilometres wide and usually contains a lava lake. The crater presently has two distinct cooled lava benches within the crater walls - one at about and a lower one at about . Nyiragongo's lava lake has at times been the most voluminous known lava lake in recent history. The depth of the lava lake varies considerably. A maximum elevation of the lava lake was recorded at about prior to the January 1977 eruption - a lake depth of about . A recent very low elevation of the lava lake was recorded at about . Nyiragongo and nearby Nyamuragira are together responsible for 40% of Africa's historical volcanic eruptions., Goma is a city in the eastern Democratic Republic of the Congo. It is located on the northern shore of Lake Kivu, next to the Rwandan city of Gisenyi. The lake and the two cities are in the Albertine Rift, the western branch of the East African Rift system. Goma lies only 13 to 18 km due south of the crater of the active Nyiragongo Volcano. The recent history of Goma has been dominated by the volcano and the Rwandan Genocide of 1994, which in turn fuelled the First and Second Congo Wars. The aftermath of these events was still having effects on the city and its surroundings in 2010. The city was captured by rebels during the M23 rebellion in late 2012, but has since been retaken by government forces., Africa is the world's second-largest and second-most-populous continent. At about 30.3 million km² (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4 % of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two "de facto" independent states with limited or no recognition., Murara was a small , short - lived , cinder cone on the flank of Mount Nyamuragira , 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 Albertine Rift is the western branch of the East African Rift, covering parts of Uganda, the Democratic Republic of the Congo (DRC), Rwanda, Burundi and Tanzania.
It extends from the northern end of Lake Albert to the southern end of Lake Tanganyika.
