US Agency for International Development Report.
Total Affected: Approximately 350,000 (U.N.)
Deaths: Approximately 147 (U.N. and USAID/OFDA field reports)
Displaced People: Approximately 250,000 (USAID/OFDA field reports)
A survey by relief agencies determined that there were approximately 229,000 people in Goma on January 23. Approximately one-third of the group moved west in DRC toward Sake. Approximately two-thirds moved east to Gisenyi in Rwanda.
Nyiragongo is one of Africa's most notable volcanoes. A previous lava lake in the deep summit crater of Nyiragongo, first reported by G.A. Von Gotzen on 11 June 1894, drained suddenly through radial fissures on 10 January 1977, killing about 70 people. Lava lake activity resumed at Nyiragongo in June 1982, but had ceased by early 1983. The lava lake at Nyiragongo was again activated after an eruption that began in June 1994.(GVP). Nyiragongo will continue to hold fascination for volcanologists.
