The Rwanda Red Cross on May 26, 2009 updated the risk-reduction plan for the communities that lie in the shadow of the volcano amid signs that it is showing increased activity again. Nyiragongo erupted in 2002, sending a river of lava through the city, destroying thousands of homes and killing dozens of people. Picture taken April 29, 2009.  (Xinhua/Reuters Photo)
