Nyiragongo Volcano Engulfs Goma

In January 2002, Mount Nyiragongo, a volcano in the east of the Democratic Republic of the Congo, erupted and sent streams of lava through the city of Goma on the northern shore of Lake Kivu. The eruption destroyed a large part of the city's center and left hundreds of thousands of people homeless, at a time when the region was already strained by war and poverty. It remains one of the most damaging volcanic events in recent African history and a lasting example of the risks facing cities built beside active volcanoes.

Nyiragongo is a steep stratovolcano in the Virunga range, notable for its deep crater, which has often held a lake of unusually fluid lava. Fluid lava can drain quickly and travel fast once the crater wall or flanks fracture. This had happened in 1977, when lava poured down the slopes within an hour or so and killed a number of villagers, though estimates of the toll vary. Goma, meanwhile, had grown rapidly. The Rwandan genocide of 1994 and the conflicts that followed drove huge numbers of refugees and displaced people into the area, and the city expanded in the shadow of the volcano. Local scientists monitored it, but funding and equipment were limited, and the surrounding conflict made fieldwork difficult.

The eruption began in mid-January 2002, when fissures opened on the volcano's southern flank. Lava flowed toward Goma in several streams, and one cut through the city, crossing the main streets and reaching the edge of Lake Kivu. It also covered part of the runway at Goma's airport. Most residents were able to flee on foot, many crossing into neighboring Rwanda, so the death toll was far lower than the scale of destruction might suggest. Reported figures were in the low hundreds, with some deaths caused by fires and explosions at fuel stores and others by toxic gases. Estimates of the number displaced run to several hundred thousand, and the damage left many people without shelter, work or markets.

In the aftermath, most residents returned and rebuilt, often directly on top of the cooled lava, since land and housing options were limited. Humanitarian agencies provided water, food and shelter, while scientists warned that the volcano remained dangerous. Lake Kivu adds a further concern, as its deep waters contain dissolved carbon dioxide and methane, and researchers have studied whether lava or earthquakes could disturb them.

Nyiragongo erupted again in May 2021, prompting another evacuation of Goma. The 2002 disaster helped strengthen international attention on volcano monitoring in the Virunga region, though the challenges of funding, instability and urban growth remain.
