The global impact of the June 1991 Mount Pinatubo eruption in the Philippines can be seen in this particle model. Immediately following the eruption large amounts of sulfur dioxide and dust spread through the earth's atmosphere. The colors in this animation reflect the atmospheric height of the particles. Red is high and blue is closer to the earth's surface.
