Slide 10: Nyiragongo volcano in Zaire near a fumerole, a volcanic vent where gases are escaping. Note the charred vegetation in the area as well as volcanic pyroclasts and ash deposits. This photo was taken during the late 1980s after one of the many episodes of active volcanism in the Virunga chain. Image credit: photo by Robert E.
