A blue-tinged pall completely obscures Nyiragongo Volcano on July 24, 2010. The blue hue suggests the plume is rich in sulfur dioxide, a toxic gas frequently associated with the emissions of Nyiragongo. Although there are no current reports of an eruption at Nyiragongo, there is a persistent lava lake within the summit caldera. Nyiragongo is located on eastern edge of the Democratic Republic of the Congo, near the border with Rwanda.
