The fastest lava flow ever recorded occurred when Nyiragongo, in the Democratic Republic of Congo, erupted on 10 January 1977. The lava, which burst through fissures on the volcano's flank, travelled at speeds of up to 60 km/h (40 mph). Up to 2,000 people were killed when the flow inundated the nearby city of Goma.
