The summit of the broad Nyamuragira shield volcano is seen here in 1990 from a vent on the upper SE flank. Lava flows from Nyamuragira cover 1,500 km² of the East African Rift. The summit is truncated by a small 2 x 2.3 km summit caldera. Historical eruptions have occurred within the summit caldera and from the numerous fissures and scoria cones on the flanks.
