Nyamuragira, Democratic Republic of Congo : presence  of a lava lake in Nyamuragira crater.

Confirmation of the presence in February 2016 of a lava lake in Nyamuragira / RDC.

We had one last chance to fly with the U.N. up to the second volcano (Nyamuragira)… The weather didn’t look good at first, it was raining and visibility was not good.
We had a South African crew, flying an Oryx helicopter, and they managed to get us up to the volcano and land. We spent about 4 hours there, observing the rarely-seen lava lake inside the deep crater.

The best part was the flight back, when the pilot let us do several spins around the crater with the doors open…. Then, we dashed back to Goma, flying extremely low and FAST, to avoid any rebel camps that have been spotted in the area. What a thrill. Here’s a pic from the chopper. More to come.”

Africa’s most active volcano, Nyamuragira, is a massive high-potassium basaltic shield about 25 km north of Lake Kivu. Also known as Nyamulagira, it has a volume of 500 cu km, and extensive lava flows blanket 1500 sq km of the western branch of the East African Rift. The broad low-angle shield volcano contrasts dramatically with its steep-sided neighbor Nyiragongo to the SW.

The 3058-m-high summit is truncated by a small 2 x 2.3 km caldera that has walls up to about 100 m high. Historical eruptions have occurred within the summit caldera, as well as from the numerous fissures and cinder cones on the flanks. A lava lake in the summit crater, active since at least 1921, drained in 1938, at the time of a major flank eruption. Historical lava flows extend down the flanks more than 30 km from the summit, reaching as far as Lake Kivu.
