Monte Nyamuragira

Nyamulagira

Volcán en escudo · DR Congo · 3058 m

The summit of Nyamuragira volcano is truncated by 2 x 2.3 km wide caldera whose floor is partially covered by unvegetated historical lava flows. This view from above the SW caldera rim shows a crater on the far side of the caldera (upper left) that was the site of a lava lake, active since at least 1921, which drained in 1938 at the time of a major flank eruption.

Resumen geológico

Africa's most active volcano, Nyamulagira (also known as Nyamuragira), is a massive high-potassium basaltic shield about 25 km N of Lake Kivu and 13 km NNW of the steep-sided Nyiragongo volcano. The summit is truncated by a small 2 x 2.3 km caldera that has walls up to about 100 m high. Documented eruptions have occurred within the summit caldera, as well as from the numerous flank fissures and cinder cones. A lava lake in the summit crater, active since at least 1921, drained in 1938, at the time of a major flank eruption. Recent lava flows extend down the flanks more than 30 km from the summit as far as Lake Kivu; extensive lava flows from this volcano have covered 1,500 km2 of the western branch of the East African Rift.
