periodic droughts in south; Congo River floods (seasonal); active volcanoes in the east along the Great Rift Valley volcanism: the active volcano Nyiragongo (3,470 m) poses a major threat to the city of Goma, home to a quarter of a million people; it produces unusually fast-moving lava, known to travel up to 100 km/hr; Nyiragongo has been deemed a Decade Volcano by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to its explosive history and close proximity to human populations; its neighbor Nyamuragira is Africa's most active volcano; Visoke is the only other historically active volcano

note 1: second-largest country in Africa (after Algeria) and largest country in sub-Saharan Africa; straddles the equator; dense tropical rainforest in central river basin and eastern highlands; the narrow strip of land that controls the lower Congo River is the DRC's only outlet to the South Atlantic Ocean note 2: the Congo River, most of which flows through the DRC, has never been accurately measured along much of its length because of its speed, cataracts, rapids, and turbulence; nonetheless, it is conceded to be the deepest river in the world, with estimates of the point of greatest depth varying between 220 and 250 meters

cobalt, copper, niobium, tantalum, petroleum, industrial and gem diamonds, gold, silver, zinc, manganese, tin, uranium, coal, hydropower, timber

note 1: coltan, the industrial name for a columbite–tantalite mineral from which niobium and tantalum are extracted, is mainly artisanal and small-scale; tantalum, tin, tungsten, and gold extracted from central Africa are considered "conflict minerals" and as such are subject to international monitoring

note 2: the DROC is the World's leading producer of cobalt, accounting for as much as 70% of the World's supply; between 20-30% of this cobalt is produced in artisanal and small-scale mining operations

slightly less than one-fourth the size of the US

urban clusters are spread throughout the country, particularly in the northeast along the border with Uganda, Rwanda, and Burundi; the largest city is the capital, Kinshasha, located in the west along the Congo River; the south is least densely populated, as shown in this population distribution map

Zaïre (Congo) river mouth (shared with Zambia [s], Angola, and Republic of Congo) - 2,920 km; Ubangi river mouth (shared with Central African Republic [s] and Republic of Congo) - 2,270 km note: [s] after country name indicates river source; [m] after country name indicates river mouth
