Nyamuragira (also spelled Nyamulagira) is a large shield volcano similar to Mauna Loa on Hawai'i and 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 traveling many kilometers into the scarcely populated area of tropical forest and farmland surrounding it.

Background

Nyamuragira is Africa's and one of the world's most active volcano. It erupts roughly every two years, producing large fluid lava flows.

Nyamuragira is is a massive high-potassium basaltic shield volcano located about 25 km north of Lake Kivu in the East African Rift Valley NW of Nyiragongo volcano. It has a volume of 500 cubic km, and extensive lava flows from the volcano blanket 1500 square km of the East African Rift, some lava flows having travelled more than 30 km from the summit. The broad shield volcano, 3058 m high, has a summit caldera, about 2 km wide and walls up to about 100 m high. During some eruptions, a lava lake is contained within the caldera. As typical for shield volcanoes, it has both eruptions inside the summit caldera and from extensive rift zones on the flanks, producing numerous fissures and cinder cones.

2011-2012 Kimanura flank eruption
A new flank eruption from started at Nyamuragira on 6 November 2011, from a series of E-W aligned fissures located about 10 km east of the summit caldera. The eruption started with intense ground fracturing (evidence of which was observed during our expedition) and tall lava fountains from several vents, that quickly started to built the western Kimanura cone complex.
Lava flows traveled many kilometers to the north, burning large areas of forest, but caused no damage to infrastructure, since the area is not populated. Tall fountaining lasted about 1 week, and moved to intense spattering from active lava-lake filled vents and strombolian explosions. Depending on the wind direction, areas surrounding the vents received up to about 1 meter of lapilli and scoria fallout. A second cluster of vents opened about 1 km down-slope on the same fissure system in early January and produced lava fountains our first expedition group in January was lucky to observe from close. Another, similar sized complex of vents built up quickly the so-called east Kimanura vent complex. Similar to the activity of the western complex, lava fountaining merged into a form of intense spattering from boiling lava lake activity and continued to fee large lava flows traveling to the north. As of 2 February, the eruption is still continuing.
It seems likely that this eruption ranks as one of the volcano´s largest during the past 100 years, both in duration and total lava volume erupted.
