Scores of fires were smoking across Sumatra (center) on June 8, 2003, trailing smoke across the Strait of Malacca, which separates Sumatra from Malaysia to the north, and also over the the Indian Ocean (bottom left). This image of active fire locations (red dots) was captured by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Terra satellite.
