The Nyamulagira volcano in the Democratic Republic of Congo is spewing out lava in what volcanologists say may be its biggest eruption in 100 years.
Experts say the volcano in the Virunga National Park does not currently threaten the town of Goma.
Park rangers have set up a camp from which visitors can view the fireworks.
