Context and objectives
Nyiragongo and Nyamulagira volcanoes are amongst the most active in Africa. They are the sources of various hazards that threaten the region of Goma (N-Kivu, D.R. of Congo). The Nyiragongo eruption that occurred in January 2002 produced spectacular lava flows that destroyed about 10-15 % of the city of Goma and paralyzed ~80 % of the regional economy. Although the amount of casualties was limited, hundred thousands of inhabitants were forced to evacuate in difficult chaotic conditions. The long term socio-economic impact of the eruption is likely the most important; it has added more pressure on populations in an unstable and sensitive area. The main objectives of this initiative are to provide these three interconnected end-users working in the Nyiragongo – Nyamulagira volcanic context with appropriate products and services to assess the volcanic hazards and to mitigate the related risks. It follows three parallel axes: strengthening of the local capacity with new products and services, transversal pluri-disciplinary approach and capacity building including implication and training of the end users. GORISK is acting upstream of the division between direct and indirect volcanic risks. The direct risks are essentially related to short-term volcanic crisis and erupted material, whereas indirect risk deals with mid- to long-term effects on the environment or/and the population.
