7. Nyamuragira, DR Congo (50)
One of the top most active volcanoes in Africa (along with its nearby neighbor Nyiragongo) saw its biggest explosive eruption in decades when a new flank fissure vent opened in November on the volcano. The Congolese government saw the eruption as a chance to lure tourists, offering camping trips with armed guards to visit the eruption, which was producing some spectacular fire fountains (see above).
