This pair of high-resolution images from the commercial Ikonos satellite shows the craters of Nyamuragira and Nyiragongo, both of which are located at the far eastern edge of Democratic Republic of Congo, north of Lake Kivu.
When the African volcano Nyiragongo erupted unusually fluid lava in January 2002, nearly 500,000 Congo citizens were displaced, and dozens were killed. The lava did not erupt from the central crater, but instead ran from fissures along the southern slopes, just north of the city of Goma.
