Mikeno volcano (center) and Karisimbi volcano (right) are seen here from the E on the flanks of Nyamuragira volcano. Mikeno is an eroded Pleistocene volcano; Karisimbi is younger. The 2-km-wide Branca caldera is located SE of the summit of Karisimbi and is filled by viscous lava flows and has two craters. More than 100 parasitic cones extend along a NNE-SSW zone to the shores of Lake Kivu.
