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's last major eruption was in 1977, when lava flows killed almost 2,000 people in less than half an hour when fast flowing lava drained from a lava lake. More on Nyiragongo Volcano.
