The Volcano Adventure Guide: Excellent information and background for anyone wishing to visit active volcanoes safely and enjoyably. The book presents guidelines to visiting 42 different volcanoes around the world.
Nyamuragira, a large shield volcano similar to Mauna Loa on Hawai'i, 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 travelling many kilometers into the scarsely populated area of tropical forest and farmland surrounding it.
The new eruption of Nyamuragira volcano on day 2 is putting on a spectacular show, producing tall lava fountains (a few 100 m high) that can be seen shooting out of the main vent and feeding a lava flow. A small elongated cone, perhaps already as much as 50-100 m high, has already formed around the vent. A video posted by the National Park can be seen at: YouTube.
Nyamuragira volcano (DRCongo): new flank eruption on 6 Nov

Nyamuragira volcano in the DRCongo started to erupt last night as park rangers of the Virunga National Park report on facebook. Nyamuragira is a large shield volcano north of Nyiragongo volcano near Goma town and belongs to the Virunga National Park. Its eruptions produce curtains of fire and large lava flows, which normally are no harm to inhabited areas as the volcano is very remote. In recent years, it has been almost impossible to access due to the presence of armed guerrilla troops hiding in this area.
Nyamuragira's eruption continues, but the lava output seems to decline. After 5 days, the new lava flows have traveled 21 kilometers and approached the road from Goma to Sae within 7 km. If the eruption continues, the flows may be able to cut the road. ...
Nyamuragira volcano (often also spelled Nyamulariga) erupted on Saturday 2nd January. The eruption was located on a fissure on the E flank where violent lava fountains from 4 vents along a new fissure were feeding a new large lava flow advancing towards the Goma-Sake road. Due to armed rebels hiding in the area, access to the eruption is not safely possible.
Africa's two most active volcanoes might erupt soon, adding to the conflict in the East Kivu region. In an interview reported in the German newspaper "Die Welt" scientist from Goma's volcano observatory are warning about possible impending eruptions of both Nyiamuragira and Nyiragongo. ...
As the Goma Volcano Observatory reports, the eruption at Nyiamuragira that had started on 27 November is probably close to its end. Lava emission from the eruptive fissure has been decreasing to a very low level. Due to the difficulty to access the eruption site because of hostile militant groups in the area, exact observations other than by overflights are near impossible.
The eruption at Nyamuragira volcano continues. Protected by military from the OCHA and MONUC missions, scientist from OVG could overfly and visit the eruption area on 29 Nov. Their report (kindly provided by Kasereka Mahinda, director of OVG, and other staff at OVG), is summarized: The location of the eruptive fissure is between the vents of Nyamuragira's eruptions in 1986 (Kitazungurwa: KT) and 2001 (Amani: AM). During the first day of the eruption, lava flows have already travelled 10 km (!) towards the west. If the eruption continues, the flow is likely to cut the major E-W artery road from Sake to Goma lifeline. Because of the important production of toxic ash from the lava fountains, GVO warns the population of the possibility of acid rain, ash-contaminated water and crops. During its eruption in 2000, 17 people were reported killed because of drinking from ash-continaminated water sources, as well as a large number of failed pregnancies. In addition, large damage was afflicted to crops and lifestock.
