The January 17 2002 eruption of Nyiragongo volcano started suddenly at 8:25 local time. The eruption effectively involved a reopening and extension of the 1977 fault system and a renewed drainage of the lava lake, followed by the eruption of some magma from a deeper source.
Nyiragongo erupted last week, spewing some 250 million cubic metres of lava - the equivalent of about 125,000 Olympic-sized swimming pools - on Goma, the largest city in eastern Congo. No one knows how many people the volcano killed.
