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.

Nyamuragira volcano in the DR Congo might be forming a new lava lake in its summit caldera. ...mehr
The volcano's last eruption from the Kimanura fissure NE of the summit caldera seems to have ended by now. Until early to mid March, a lava lake was observed in the eastern vent and a strong heat source could be detected on satellite imagery, but has now disappeared. Seismic explosion signals from a source under the summit were noted on 24 February from the summit crater and overflights showed increased degassing from the central pit, which contained a lava lake until 1940. This activity increased in April and a strong SO2 odor from this area suggests the presence of near-surface magma. Scientists and the park rangers are speculating about the possibility that a new lava lake in the summit crater might be about to form. [less]

Während unserer letzten Expedition die, wir besuchten Nyamuragira\ die fortlaufenden Eruption während 22-25 Januar, und gefunden, dass die Eruption noch stark, aber etwas weniger intensiv als während der ersten 1-2 Wochen im Januar. ...mehr
Die zweite Vent Komplex, die sich schon NE Ende der eruptive Fissur in Ende Dezember oder Anfang Jan mit etwa einer Woche der Konstante konnten zu bilden, besteht wahrscheinlich 3 als coalescent Dolden-. Die mittleren und größte von ihnen enthalten einen Krater kochende Lava, d. h. eine kleine Lava Lake, der stark alle paar Sekunden Schlackenwurf war voller. Der Lavasee selbst war nicht sichtbar, aber von der starken Glühen und der zischenden Entgasung Lärm der explodierenden Gasblasen, die Flüssigkeit Spritzer Bomben in alle Richtungen ausgeworfen abgeleitet werden könnte.

Lava fountain from Nyamuragira during our tour on 8 Jan 2012
During expedition to Nyiragongo in Jan 2012, we undertook a side trip to see Nyamuragira still in eruption. Lorraine sent us the following impressions of impressive lava fountains from the new vent (taken 8 Jan).
As our group who just came back reports (see last post below), the eruption of Nyamuragira seems to have intensified again. ...mehr
We are planning an expedition to see this eruption in the next week. If you are interested, please get in touch with us as soon as possible! Planned tour date: 21 Jan (arrival in Kigali) - 25 Jan (back to Kigali) [less]

To the delight of our expedition group heading towards Nyamuragira and Nyiragongo tomorrow, the lava flows from Nyamuragira are still active. NASA Earth Observatory has released spectacular images from 3 January showing the vast lava flows from Nyamuragira volcano's current eruption. ...mehr
Nyamuragira (also spelled Nyamulagira), is a massive basaltic shield volcano located north of Goma (DR Congo) and near the other active volcano, Nyiragongo, famous for its permanent lava lake. Nyamuragira is one of Africa's largest and most active volcanoes. Its current eruption started in November 2012 from a flank vent located in an uninhabited area about 10 km ENE side of the volcano's summit. [less]

The flank eruption of Nyamuragira volcano north of Goma city, DRCongo, which had started in early November, is still going on, although at much smaller intensity than during the first weeks. ...mehr
A significant plume of sulfur dioxide and a thermal anomaly are visible on satellite images, indicating that there is still effusion of lava, probably accompanied by strombolian activity at the new vent. [less]
Der Ausbruch des Nyamuragira (9 Nov, Foto: Cai Tjeenk Willink-Virunga National Park)
Die Eruption am Nyamuragira, erklärt die "größte ein in 100 Jahre" in den Medien (wohl, vielleicht ist es eher eine der am meisten zugänglich und schön), weiterhin in der zweiten Woche. Der Virunga-Nationalpark in Goma bietet geführte Übernachtung Touren zu den Ausbruch des Vulkans aus der Nähe sehen.Es scheint, dass Lavafontänen immer noch aktiv sind und 200-300 m Höhe erreichen und bereits eine beträchtliche, wahrscheinlich aufgebaut haben ca. 100 m hohen Flanke Kegel.
Der neue Ausbruch des Vulkans Nyamuragira am Tag 2 setzt auf eine spektakuläre Show, Herstellung von hoch Lavafontänen (wenige 100 m hoch), die von den wichtigsten Abzug schießen und Fütterung ein Lavastrom gesehen werden können. Ein kleiner länglicher Kegel, hat schon so viel wie 50-100 m hohen, vielleicht bereits um den Abzug gebildet.Eine Video von der National Park kann man bei: YouTube.
The new fissure eruption of Nyamuragira on the evening of 6 Nov (photo: Virunga National Park)
Nyamuragira Vulkan in der DR Kongo begonnen, letzte Nacht als Parkwächter des Virunga National Park über facebook ausbrechen. Nyamuragira ist ein großer Schildvulkan nördlich des Vulkans Nyiragongo bei Goma Stadt und gehört zu den Virunga-Nationalpark. Seine Ausbrüche produzieren Vorhänge Feuer und große Lavaströme, die normalerweise keinen Schaden zu bewohnten Gebieten, wie der Vulkan ist sehr abgelegen. In den letzten Jahren hat es fast unmöglich, den Zugriff auf die Anwesenheit von bewaffneten Guerilla-Truppen versteckt in diesem Bereich.
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. ...mehr
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. ...mehr
Although working and living conditions in Goma are extremely difficult, to say the least, the scientist are still trying theri best to monitor both volcanoes. Head of the observatory, Kasereka Mahinda, is convinced that an eruption from Nyimuragira is going to happen soon - the volcano tends to erupt on average every 1-2 years and the last one was in late 2006, paired by increased seismicity. Also Nyiragongo volcano, which destroyed the centre of Goma in 2002 with a large flank eruption, is threatening to erupt. Mahinda points out that often both volcanoes are erupting at the same time. During the last visit of the scientists to Nyiragongo's crater in October a noticeable rise in the magma level of the lava lake was observed. Much of the observatory's monitoring equipment has been looted, Mahinda explains, making more detailed analyses impossible, and there seems to be no way to reinstall. [less]
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.

One of the world's largest volcanoes, mighty Nyamuragira (also spelled Nyamulagira) in eastern Congo, is in eruption again. The eruption began around 10 pm local time on Monday, 27 Nov. 2006 as press reports.Observation of the eruption is difficult because of the unrest in the region. The area around Nyamuragira is difficult to access and home to a number of armed rebel troops notoriously opposing the government army. The volcano, notorious for its fluid lava, last erupted in 2002 and 2004, sending lava flows into mostly uninhabited forest and farm land.
