Lake Kivu in the context of "Mount Nyiragongo"

Goma is a city in the eastern Democratic Republic of the Congo. It is the capital and largest city of the North Kivu Province; it is located on the northern shore of Lake Kivu and shares borders with the Bukumu Chiefdom to the north, Rwanda to the east and the Masisi Territory to the west. The city lies in the Albertine Rift, the western branch of the East African Rift, and is only 13–18 km (8.1–11.2 mi) south of the active volcano Mount Nyiragongo. With an approximate area of 75.72 km (29.24 sq mi), the city had a population of 782,000 people in 2024,with an additional 500,000 displaced people.

Goma is administratively divided into two urban municipalities: Goma and Karisimbi, which are further subdivided into 18 quarters, colloquially recognized as "neighborhoods" in the English lexicon. The city is home to several notable landmarks, including Goma International Airport, the UNESCO World Heritage Site Virunga National Park, the private Christian co-educational school Adventist University of Goma, the University of Goma, and is also surrounded by the active Virunga volcanic range, which includes volcanoes Nyamulagira, Nyiragongo, Mikeno, Visoke, Gahinga, Karisimbi, and Sabinyo. Goma also hosts the annual Amani Festival, the Free University of the Great Lakes Countries, which supports local development initiatives, as well as the regional cultural center and art school, Foyer Culturel de Goma.

North Kivu (Swahili: Jimbo la Kivu Kaskazini) is a province bordering Lake Kivu in the eastern Democratic Republic of the Congo. The capital city is Goma. Spanning approximately 59,483 square kilometers with a population estimate of 8,985,711 as of 2020, it is bordered by Ituri Province to the north, Tshopo Province to the northwest, Maniema Province to the southwest, and South Kivu Province to the south, as well as Uganda and Rwanda to the east.

North Kivu's administrative history traces back to the colonial era when it was initially part of the Stanley Falls District within the Congo Free State. Following a series of territorial reorganizations, North Kivu became incorporated into Orientale Province, with Stanleyville (modern-day Kisangani) as the provincial capital. The area gained provincial status in 1962 but was demoted to a district under Mobutu Sese Seko's regime in 1965. It was formally reinstated in 1988 under Ordinance-Law No. 88/1976 and Ordinance-Law No. 88-031, which redefined the previous Kivu Province into tripartite separate provinces: North Kivu, South Kivu, and Maniema. Presently, North Kivu comprises three cities—Goma, Butembo, and Beni—and six territories: Beni, Lubero, Masisi, Rutshuru, Nyiragongo, and Walikale. A 2013 decree also proposed city status for Kasindi, Oicha, and Luholu. The province's eastern border is home to the Rwenzori Mountains, part of the Albertine Rift, which serves as a key freshwater source and supports a diverse ecosystem. North Kivu also hosts Virunga National Park, a UNESCO World Heritage Site home to endangered mountain gorillas.

South Kivu (Swahili: Jimbo la Kivu Kusini; French: Sud-Kivu) is one of 26 provinces of the Democratic Republic of the Congo. Its capital is Bukavu. Located within the East African Rift's western branch Albertine Rift, it is bordered to the east by Lake Kivu, Rwanda, Burundi, and Tanzania; to the west by Maniema Province; to the north by North Kivu Province; and the south by Tanganyika Province. The province covers an area of approximately 69,130 square kilometers and has an estimated population of 8,147,400 as of 2024.

The region has historically been inhabited by various Bantu-speaking ethnic groups, including the Bamushi, Bafuliiru, Bahavu, Banyindu, Babembe, Babuyu, Balega, Babwari, Baholoholo, Banyanga, Bavira, Bakusu, Batembo, Barongeronge, and Baswaga, as well as Pygmy communities. During the colonial period, the borders of the Congo Free State were established by the 1885 Berlin Conference, placing all of Lake Kivu and both banks of the Ruzizi River within the Free State. The region's boundaries were later subject to disputes, including the Kivu frontier incident of 1909, which was resolved in 1910 when the eastern portion of Kivu was allocated to Uganda Protectorate and German East Africa. Kivu District was formally created in 1912 and later divided into Sud-Kivu and Nord-Kivu Districts in 1951. After a series of administrative reorganizations, South Kivu became a separate province in 1988, alongside North Kivu and Maniema.

The Virunga Mountains (also known as Mufumbiro) are a chain of volcanoes in East Africa, in the area where Rwanda, the Democratic Republic of the Congo (DRC), and Uganda meet. 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 mountain range consists of eight major volcanoes. Most of them are dormant, except Mount Nyiragongo 3,462 metres (11,358 ft) and Mount Nyamuragira 3,063 metres (10,049 ft), both in the DRC. Recent eruptions occurred in 2006, 2010 and May 2021. Mount Karisimbi is the highest volcano at 4,507 metres (14,787 ft). The oldest mountain is Mount Sabyinyo, which rises 3,634 metres (11,923 ft) above sea level.

Lake Nyos (/ˈniːoʊs/ NEE-ohs) is a crater lake in the Northwest Region of Cameroon, located about 315 km (196 mi) northwest of Yaoundé, the capital. Nyos is a deep lake high on the flank of an inactive volcano in the Oku volcanic plain along the Cameroon line of volcanic activity. A volcanic dam impounds the lake waters.

A pocket of magma lies beneath the lake and leaks carbon dioxide (CO₂) into the water, changing it into carbonic acid. Nyos is one of only three lakes known to be saturated with carbon dioxide in this way, and therefore prone to limnic eruptions (the others being Lake Monoun, also in Cameroon, and Lake Kivu in the Democratic Republic of Congo and Rwanda).

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.The geographical term includes the valley and the surrounding mountains.

Nyamuragira, also known as Nyamulagira, is an active shield volcano in the Virunga Mountains of the Democratic Republic of the Congo, situated about 25 kilometres (16 mi) north of Lake Kivu. The name is derived from Mashi language.

It has been described as Africa's most active volcano and has erupted over 40 times since 1885. As well as eruptions from the summit, there have been numerous eruptions from the flanks of the volcano, creating new smaller volcanoes that have lasted only for a short time (e.g. Murara from late 1976 to 1977).

Tchegera Island (French: Île de Tchegera) is a U-shaped caved-in volcanic caldera island located northwest of Lake Kivu and southwest of Goma, within the Virunga National Park in the eastern region of the Democratic Republic of the Congo. The island forms the park's southwestern boundary and is the only portion of Virunga located in the South Kivu Province, specifically in the Kalehe Territory. Administered by the Institut Congolais pour la Conservation de la Nature (ICCN), the island is a significant center for ecotourism, featuring tourist reception facilities such as safari-style tented camps that provide an ideal environment for relaxation and restoration.
