In this file photo taken Thursday, January 24, 2002, a Congolese man pushes his bicycle across lava rock covered in steam, after a rain storm in the eastern Congolese town of Goma. Traumatized farmers are slowly returning to fields decimated by the 2002 eruption of Mount Nyiragongo in eastern Congo. Flowing lava flattened more than 30 percent of the city of Goma, 20 kilometers away. (Photo by Karel Prinsloo/AP Photo)
