  Mount Nyiragongo - Wikipedia, the free encyclopedia
Nyiragongo and nearby Nyamuragira are together responsible for 40% of Africa's historical volcanic eruptions.
Volcanism at Nyiragongo is caused by the rifting of the Earth's crust where two parts of the African Plate are breaking apart.
Lava lakes reformed in the crater in eruptions in 1982-1983 and 1994.

The town of Goma is 11 miles (18 km) south of the summit of Nyiragongo and on the shore of Lake Kivu.
From June 1982 to early 1982 the volcano was active with a lava lake in the crater and phreatic explosions and lava fountaining.

The volcano is quiet." Although no new lava flows were threatening the city, some scientists feared that lava entering the lake or seismic activity could perturb the lake sufficiently to release significant amounts of carbon dioxide and methane gas lying at the bottom of the lake.
During a visit to the volcano during 6 and 7 May scientists saw that the lava pool in the crater was very active, with violent gas outbursts, projection of spatter and surges, and lava splashing the walls of the pit.
The Toulouse VAAC reported that satellite imagery showed a weak eruption of Nyiragongo on 21 May. Activity intensified during the evening of 24 May. By the evening of 25 May, the volcano was no longer visible on satellite imagery due to meteorological clouds in the area.

 EO Natural Hazards: Nyiragongo Volcano Erupts in the Congo
Mount Nyiragongo, located in the Democratic Republic of the Congo, erupted today (January 17, 2002), ejecting a large cloud of smoke and ash high into the sky and spewing lava down three sides of the volcano.
Mount Nyiragongo is located roughly 10 km (6 miles) north of the town of Goma, near the Congo?s border with Rwanda.
Nyiragongo eruptions are extremely hazardous because the lava tends to be very fluid and travels down the slopes of the volcano quickly.

 Guardian Unlimited | Special reports | City fears return of 50mph river of fire
Mount Nyiragongo is undergoing a "feeding episode" which appears to have started on November 10, according to the Goma Volcano Observatory, an international monitoring group based in the city.
It is the sixth time since 1972 that Mount Nyiragongo has been recorded feeding from its 15 mile-deep magma core, a phenomenon which results in important rises in the lava lake but do not systematically trigger eruptions, the observatory says.
Host to the biggest of the world's three lava lakes, Mount Nyiragongo sits in the Virunga mountains, which are on the border between Rwanda and the North Kivu province of the Democratic Republic of Congo.

Nyiragongo razed much of Goma in January in Africa's most destructive volcanic eruption for 25 years.
Vulcanologists said the current danger was that rising lava inside Nyiragongo would force a breach in its flanks, not that the lava would overflow the rim of the 0.75-mile-wide crater.
They said the molten rock had risen rapidly inside Nyiragongo in the last two weeks, but it was difficult to assess the risk in the notoriously unpredictable mountain.

Nyiragongo is one of eight volcanoes on the borders of Rwanda, the Democratic Republic of Congo and Uganda, a region dense with tropical forests and famously home to rare mountain gorillas.
However the gorillas inhabit only the slopes of the six dormant volcanoes, and experts said they should be safe from direct impact from the destruction inflicted by Nyiragongo on the town of Goma and nearby forest.
When Nyiragongo last erupted in 1977, killing scores of people and gutting the town, there were reports of elephants being found in the rubble alongside the human debris of cars and houses.
