This photo-like image from August 4, 2010, shows intense fires burning across central Russia and a thick plume of smoke stretching about 3,000 kilometers (1,860 miles).
A river of smoke several hundred kilometers wide flowed off the southeast coast of Africa in early September 2008. The smoke was coming from hundreds, probably thousands, of fires burning in Mozambique, South Africa, and Swaziland.
Though fires across Russia appeared to be less intense than previously, these photo-like images show thick smoke rising from two regions in western Russia on August 15, 2010.
