Volcano Type: Stratovolcano
Volcano Status: Potassium-Argon
Last Known Eruption: 8050 BC (?)
Summit Elevation: 4507 m 14,787 feet
Latitude: 1.50°S 1°30’0″S
Longitude: 29.45°E 29°27’0″E
Karisimbi, the highest of the Virunga volcanoes, is a complex volcano with a symmetrical sharp-peaked summit. The 2-km-wide Branca caldera, located SE of the 4507-m-high summit, is filled by viscous lava flows and two explosion craters. The large, 1.2-km-wide Muntango pit crater is located south of the summit of the basanitic-to-trachytic volcano. A broad lava plain, formed from lava flows erupted within the caldera and along a chain of parasitic cones, extends SW. More than 100 parasitic cones erupted along a NNE-SSW zone that extends to the shores of Lake Kivu. The youngest Potassium-Argon date obtained is about 10,000 years before present (de Mulder, 1985). The youngest eruptions from Karisimbi produced a group of dome-shaped parasitic vents east of the caldera, which fed viscous lava flows that traveled as far as 12 km to the east, and lava flows from the SW-flank satellitic lava vents.

Volcano Type: Stratovolcano
Volcano Status: Historical
Last Known Eruption: 1957

The symmetrical Visoke volcano is the NE-most of a cluster of large stratovolcanoes at the southern end of the Virunga Range on the border of the Democratic Republic of Congo and Rwanda. The 3711-m-high stratovolcano contains a 450-m-wide lake in its summit crater. A NE-SW-trending fissure zone has produced many cinder cones NE of the trachyandesitic volcano. An eruption in 1957 formed two small cones on the north flank, 11 km from the summit.
 Visoke Volcano in Virunga National Park The symmetrical Visoke volcano is the NE-most of a cluster of large stratovolcanoes at the southern end of the Virunga Range. The 3711-m-high stratovolcano contains a 450-m-wide lake in its summit crater (left center). Lobate lava flows descend the flanks of the volcano. A NE-SW-trending fissure zone has produced many cinder cones NE of the volcano (top). An eruption in 1957 formed two small cones on the north flank, 11 km from the summit.

Nyamuragira, a large shield volcano similar to Mauna Loa on Hawai’i, is one of Africa’s most active volcanoes. Every few years, it produces eruptions often from radial fissures emitting lava fountains and large, fluid lava flows travelling many kilometers into the scarsely populated area of tropical forest and farmland surrounding it.

One of Africa’s most notable volcanoes, Nyiragongo contained a lava lake in its deep summit crater that was active for half a century before draining catastrophically through its outer flanks in 1977. In contrast to the low profile of its neighboring shield volcano, Nyamuragira, 3470-m-high Nyiragongo displays the steep slopes of a stratovolcano. Benches in the steep-walled, 1.2-km-wide summit crater mark levels of former lava lakes, which have been observed since the late-19th century. Two older stratovolcanoes, Baruta and Shaheru, are partially overlapped by Nyiragongo on the north and south. About 100 parasitic cones are located primarily along radial fissures south of Shaheru, east of the summit, and along a NE-SW zone extending as far as Lake Kivu. Many cones are buried by voluminous lava flows that extend long distances down the flanks of the volcano, which is characterized by the eruption of foiditic rocks. The extremely fluid 1977 lava flows caused many fatalities, as did lava flows that inundated portions of the major city of Goma in January 2002.
